musclecar neal - (your quote) "Sounds like they are legit or ????" Well, after you read through some of the horror stories at www.realoldspower.com and check out the other links I've listed above, you may see differently.

(Your quote) "They tell me that olds has been using cast iron cores on roller cams since 1980. They offered to send me a cast iron roller cam free of charge for me to inspect. I have never seen a cast iron roller and think I will take them up on the offer to see what the heck it is."

Here, I'll give you a little preview of what they look like after only 7000 miles.

This is supposed to be a hydraulic roller camshaft, it was installed with their spacer and thrust button/bolt, and was centered properly when motor was built. Now, no matter if it's cast or not, it only looks like a flat tappet camshaft, because that's what it really is.

Here is link that will show you my copy of the invoice:

musclecar neal - I sure would like to hear back from ya...

Thanks!
Robin

I see you have caught on to Joe Schubeck.
His ideas sound really good.
The best part is that his lifters are lighter than stockers and you'll only need to buy ONE set for the life of your engine,no matter how many times you change cams or rebuild the sucker.
That's sweet.:D
 
Radius Kid - I agree 110%, UDHarold is the man for camshafts, hands down, a wealth full of knowledge. That man, eats, sleeps, and breaths camshafts. I've never heard a bad word about Ultradyne. It's all been good.
Wow! I just noticed the Social Distortion skeleton, and Suicidal Tendencies lyrics under your name. That's the true blue old school punk rock stuff I grew up listening to, as well as T.S.O.L., Black Flag, Circle Jerks, DK's, and much, much more. Gotta love it!

musclecar neal - Yes, it is totally unreal what has become of Mondello, that Lynn dude is a low down dirty lying, scam artist, trying to get over on everyone. Gotta run for now, but I will be e-mailing you soon with more.

Thanks a million!!
Robin

Huh?Me?
I'll agree on the Ultradyne stuff as well.:)
Later.
 
Ooops!! Sorry bro, I'd meant WFO, not Radius Kid, ..my bad. (lol!)
Geesh, I think I've prolly got too many irons in the fire at once. (ha!ha!ha!!) =)

Robin
 
WOW!!

I just spent the last 25 min talking to Joe Mondello about the cams in question. As always Joe is the consumate proffesional. He was very busy but took time out to go over the issues at hand.

I have to say Joe has a very good explanation of the possible cause of this cams failure. I also went over the problems with the CompCams budget roller we had for our engines.
The cam core used for the bugget roller were regular cast iron cores. The same material used in flat tappet cams. The material used in his Hyd rollers is Nodular iron with a deep heat treat.


We spoke about the R&D work he did to create the cams he sells. And the R&D work he does for Comp. He said that the cores Comp used were just not up to the task from a materials standpoint. He said that all the factory rollers used by the big 3 are using the same material he is using. He also went on to say that the over the nose spring pressures are in the 280 lb range in the performance applications in the OEM. He has used 370 pound pressures and never had a problem. I must sit back and think who I am talking to. The man is a Legend. He is a expert. He was very straight forward and pulled no punches. He made no excuses. He offered to have the cam and lifters sent to him personally and he would make things right. Lynn is sending me 2 cams to compare and let me make my own decisons. Joe stated thet there are only 2 billet cam cores availble for the Olds. Both are made by Crane. He cannot make the profiles needed with these cores. The lobes on those cores are too big. That is why they use the cast Nodular iron cores for these small street cams.

Joe told me many things I dont think would be right saying here. I trust the man and always have. I will report on the cams when they arrive and hope I can help Robin get things sorted out.

Robin. Please email me so I can help.

Neal
 
so you're telling me that lobe in the picture is supposed to be a roller profile?doesn't look like any roller cam i've ever had my hands on.what's the point of running a regular cam lobe with a roller lifter?even if it was billet all you'll gain is some reduced friction.it's my understanding that the advantage of a roller is the more aggressive lobes...:confused:

Sorry 'bout the delay with my response, as I was out of town for two days.

Neal - I would like to thank you for taking the time to help me with this, your efforts are very much appreciated. There aren't too many people these days that would go way out of their way to help with a situation such as this.
I had tried to call Joe too, but the lady said that he was not in at the time. (Your quote) "The material used in his Hyd rollers is Nodular iron with a deep heat treat.", over a week ago when I had called Engle Performance Cams to ask about what type of core was supposed to be used for this particular grind cam that was for Mondello, he said that they use both cast iron and 8620 billet. I told him what had happened with my camshaft and he asked me what the casting numbers were on my cam, I had said that it is "EP-28", so he then told me that EP-28 means it is a cast iron core and was never intended for hydraulic roller lifters with those kinds of spring pressures, and that it surely would fail if used that way. I asked him if he was aware that Mondello recommends a spring pressure max of 140lbs at the seat, and 340lbs open, he said that he was not aware of that, and that an EP-28 would surely fail if used with roller lifters at these pressures. With that being said, I would have to say that Joe does not quite fully understand that the failed cam in question here, in fact, was NOT ever intended for hydraulic roller lifters (especially at their recommended spring pressures!), and is clearly NOT what I'd ordered, and it is NOT what I was billed nearly for $400 for! It clearly says "HYDRAULIC ROLLER CAMSHAFT" on my invoice. Furthermore, Mark Engle himself says, EP-28 casting is NOT hard enough for hyd roller lifters.
Here's something VERY interesting too!!! Take a look at the picture here: http://im1.shutterfly.com/procserv/47b3dc38b3127cce94fcab4aeab10000001610 This is of my failed camshaft, please notice the "RH6-14HYD" stamped into it.
NOW, look at this picture that was sent to me from a member of the realoldspower forum: http://im1.shutterfly.com/procserv/47b3dc38b3127cce94fc98102b5a0000001610
...this pic is of his billet steel hyd roller, and is exactly what I was supposed to get. Notice the same "RH6-14HYD", here's what it looks like: http://im1.shutterfly.com/procserv/47b3dc38b3127cce94fc989baae10000001610
(Your quote) "Joe stated thet there are only 2 billet cam cores availble for the Olds. Both are made by Crane. He cannot make the profiles needed with these cores. The lobes on those cores are too big. That is why they use the cast Nodular iron cores for these small street cams."
Clearly in the picture (link above) of the small street cam, it IS billet steel, and also a Mondello/Engle camshaft, so what's up with that???

Also, it is my understanding that Mondello does nothing of the sort to further heat treat any of the cams he gets from Engle, they are already finished and ready for use. Lynn had once told me something similar too, that they order pistons, and cams from a couple different mfgr's, then once received, they then do some Mondello's special machining work to mod them to their own specs, then sell them. Maybe on some items this might be true, but certainly not for his cams and pistons.
I agree that Joe Mondello himself has always been a respectable, reputable guy, who really knows his ****. However, these days, he spends all of his time teaching classes on engine rebuilds at the Mondello engine tech school, and has no part of anything to do with the product sales. Lynn has been fully in charge of that category of Mondello, and it is quite evident that Joe Mondello is not aware of just how many people have had nothing but problem after problem with the products part of his buisiness. Then again, for being 62 years old, he might not even be that concerned about it, who knows.
I did talk to Lynn about this cam with no reasonable resolution, he told me to send him the cam (at my expense), and he'd check it out, and IF it appears to have failed from being a bad core, he'd replace it free of charge. Well, that is NOT any reasonable resolution at all, I shouldn't have to pay for LYNNS INCOMPETENT, NEGLEGENT, and CARELESS MISTAKES, and his CONTINUAL BAD BUISINESS PRACTICES??? What about all the damage that was done to my engine from all of the shreds of cast iron material of that cam that trashed out the $1500 in machine work that was done just weeks before that cam was ever installed? What about all of the cam, rod, and crank bearings that were trashed from it? What about the 16 hyd roller lifters that I'd paid over $300 for? The list goes on, I'm NOT even asking for any compensation for any time or labor. I have all receipts to prove what was spent for the mentioned items, as well as pictures of these said items after only 7000 miles of mild usage, and as a direct result of the camshaft failure, NEED TO BE REPLACED!!!

I think it's very reasonable for Mondello Performance Products to pay for mainly the following items:

price of new camshaft
price of new hyd roller lifters
price of all bearings
price of all gaskets and seals
price of having crankshaft turned and polished

The term, "price of", means cash, does NOT mean, in house credit for Mondellos' products only. I do not ever want their products used in my engine again. Been there, done that.

Does this sound pretty reasonable and fair to you guys???

Thanks!
Robin
 

now that's a roller cam!look at the base circle and the shape of the lobes.

yes,it's reasonable but unfortunately it'll never happen.just my opinion,but i think they know exactly what they're doing and if you press the issue you'll get the old "no warranty on race parts" crap:mad: .

i think your only hope might be to prove that you paid for a billet roller cam and got a friggin cast hydraulic flat tappet.did you get a cam card with your "roller"?if you did i'd have a reputable shop measure all the specs and prove that you didn't get what you paid for and you might at least get a real roller out of the deal.i doubt they'll give you any $$.:( :mad:

good luck.

From another perspective - Mondello had extended me an Expressed Warranty - that they were selling me a Widget. They violated this by instead sending me a Thingamabob. This means that I am entitled to either a Widget, or my money. However, any other limiting warranties (Example: we are not responsible for damage incurred by our Widget . . . .) are also void, as they never sold me a Widget, they'd sold me a Thingamabob. Even if the written warranty is generalized (PRODUCT, instead of specifically a Widget), the reciept I have, as well as the telephone conversations, and email records, all state that it is a Widget they'd sold me, and as this is the "product" they refer to, if it is not a Widget, the warranties do not apply. Therefore, I may be entitled to the money for all damage incurred to my engine, because the fact I am not a well known profesional engine builder like Joe Mondello is completely moot - they'd never sold me the right parts, so there was no possible way to have installed them correctly. Therefore, they could not be installed incorrectly, either.
I know that I have a very strong case, but may or may not be rewarded a settlement for the sum off all damaged engine parts, but I'm NOT gonna just chalk it up to a loss and take it in the ass. THAT, quite simply ain't gonna happen.

Thanks a million!!!
Robin
 
Sounds like you may have a case for fraud.
I'd look into it and see if it's possible[Postmaster general?]
Then have a chat with Mondelo after you've got all your ducks in a row.:)
 
I'm a little unsure of what you mean by the following: [postmaster general?]
Please go further, (lol!) you kinda threw me for a loop with that one.

Thanks!
Robin

Isn't that who handles fraud cases in the States[mail fraud anyway]?
I would check with their office and see if they can help.
 
Oh ok, I see what you was trying to say now, just had wondering a little bit. (lol!)
Yeah, I'll check it out.

Thanks!!!

Well, I've been looking everywhere for some information that is more geared towards the question of; What really determines when it is acceptable to use hyd. roller lifters on a cast iron hydraulic roller camshaft? If this is acceptable at all, with what valve spring pressures? From what I have gathered from several people here, and abroad, is that it should never happen, hyd roller lifters on cast iron will not work, however, I am trying to prepare for if I ever have to present my case in an extremely potential small claim lawsuit. I'm looking for pertinent information on the subject.
Even a written, signed statement from any individuals and/or buisinesses that are experienced and/or educated in the field, either an experienced professional engine builder, an experienced machinist, or metalurgist. The statement would only need to be in short, and addressing reason(s) as to why hydraulic roller lifters shouldn't be used on a cast iron camshaft, and maybe also add what has been known (from your perspective) to happen in the past when Comp Cams had tried this same combination of parts, which had resulted in countless camshaft failures (re: econo budget roller problems).
If anyone can possibly help me out with this, it'd be very much appreciated. Please let me know, either reply or private message me.

Thanks a million!!!
Robin

P.S. I really need some help with this part of the process guys. Any and all help given would be very appreciated. Thanks again!!
 
the best thing you could do would be to get some kind of documentation from engle stating that their cast cams are for flat tappets,not rollers.

if engle states clear-cut intended useage for their product and mondello sells it as something it's not he is clearly liable.

good luck:( .keep us updated.

later,sean

p.s.:i wonder if this is the mopar version:confused:

http://www.hughesengines.com/www/hughesengines/cams/bhydroller.asp

hughes gets their cams from engle.i was kinda wondering why they'd make roller cams with such sissy lobes...
 
Well It looks like the guys that you spoke to at Engle are clueless. Mr. Engle's sons might need to check what they are making. I have the 2 cams Joe sent me at the shop. I have carefully inspected them and the cams are both from Engle. One is a hyd flat tappet one is a hyd roller. the lobes are very different as they should be. The core for the Hyd roller is the EP-28. The cam is ground correctly as a hyd roller and the cam boxed and marked hyd roller from engle. Looks like the guys at Engle really need to make sure what they are saying. The hyd roller looks very nice. I would like better pics of your cam from a few angles so I can look at the lobes. I think you were shipped a flat tappt cam by mistake. I agree that you paid way too much for and iron roller cam. I would like to see exactly what you have as Joe wants to hear back from me on this to try and make it right. On getting what you want. I think that will never happen as I have never seen any company have to pay for damage done to other parts from failures of the parts they sell. That's just from my 25 years in the business. Your results may vary but I would place a large bet on getting this made right but not as you want.

Please send me the pics of you cam from a few angles so i can really see the lobe profiles.

Thanks

I am really trying to help you make it as right as I can.

Neal - I'll be e-mailing you some pictures either tonight (2-24), or by morning at the latest. I sincerely appreciate what you are doing on this. I have taken this cam to three different machine shops, and two professional engine builders, and after looking at it they all had said the same thing, there is no doubt that this was, in fact, is hyd flat tappet camshaft. These lobes were cut at a slight angle, as flat tappets do, to offset the cam thrust movement. This is also why this cam was being pulled back hard and wearing further into the block. Keep in mind, the Olds distributor rotates counter-clockwise, opposite of Buicks and many others. The camshaft was centered in the block when it was built, we checked for any excess travel, and was within the amount allowed. We also turned the crank with a breaker bar and watched through a lifter bore all appeared to be good. Over time, the cam eventially was moving further into the block due to the way the flat tappet lobes are slightly angled.
I really don't want to drag this through small claims, but Lynn was a complete azzhole to me on the phone, as he always is to most of his customers, and then by dancing around the truth and turning it back around saying it was because of this or that, but nothing to do with his cam, ..it really pushes me further into going through the courts. Joe should first make one thing right for himself, by removing Lynn Welfringer from his position, as his record shows that he has many complaints about his dishonesty, carelessness, and bad buisiness practices. The bad word travels twice as far, and twice as fast as the good word.
After going over all of this with an attorney, there is a very solid case, with very high potential in my favor. This matter is thoroughly covered by the Federal Consumer Protection laws, as well as the Uniform Commercial Code (Article 2). Read the following.

Mondello Performance Products, Inc, had extended me an Expressed Warranty - that they were selling me a Widget. They violated this by instead sending me a Thingamabob. This means that I am entitled to a Widget, or my money. However, any other limiting warranties (such as "we are not responsible for damage incurred by our Widget . . . .") are also void, as they never sold me a Widget, they sold me a Thingamabob. Even if the written warranty is generalized (PRODUCT, instead of specifically a Widget), the reciept I have, as well as telephone conversations and e-mail records, all state clearly that it is a Widget they'd sold me, and as this is the "product" they refer to, if it is not a Widget, the warranties simply do not apply. Therefore, I may be entitled to the money for all damage incurred to my engine, any question regarding qualifications, education, or experience of the installers, and/or engine builder(s), is moot, ...they never sold me the right parts, so there was no possible way to have installed them correctly. Furthmore, they could not be installed incorrectly, either.

I am being very reasonable and extremely down to earth about this entire thing. Of coarse I don't wanna take anyone to court, that CAN be avoided. It sucks that we live in such a "lawsuit driven society" these days, and it's far too often that someone will file a lawsuit, when it very easily could've been avoided and settled otherwise. It is sad, but too true. It would only be fair for Joe to cover the very few things that I have mentioned. I'm simply asking for a very small fraction, which is nothing near what I am otherwise entitled to. FAIR is FAIR, bottom line.

Neal - Check your mailbox in the morning, I'll have the pics to you by then. Thanks again!!!
 
Cam Design..

If the cam has tapered lobes, it is CLEARLY not a roller grind. I'm curious, though. Didn't it have some kind of bearing to keep it from moving back and forth, damaging the block? Except for Fords and Mopars, that's pretty standard, and part of the reason that the costs go up for rollers. You can take it to the nearest good tech school or college, and get someone to do an ID on the material for you. They can check for surface hardening, as well as identify it as to type of iron/steel, and probably do it for free. Some grinders are using hardened iron shafts, so they can avoid having to put on a separate distributor drive gear, like they would use with a billet steel shaft. It costs more than an unhardened iron shaft, but less than the total for the billet plus the drive gear.
