Running Alky? Check this out...........

[TurboBuRick]

Just installed a pcv catch can and discovered something very interesting. Alky can push into the pcv system and get into the motor oil. I have a check valve but its not working 100%. More alky in the catch than anything.
Everyone running alky you better make sure your pcv checks are up to par.

As it turns out the catch is serving another pourpose. It will also catch alky contamination that would otherwise end up in the motor oil.

What up Rick?

I got to check your catch can out on your car and get one on mine when I get the kit hooked up. I think I read somewhere that you need to change the oil more often when using alky.

Mike, what up dawg?

Ya, I wonder if thats the reason. If the damn check valve did its job it should'nt be a problem. If this is the case alky kit makers should include pcv check valve in the kits. No?

AC Delco

AIR, there has been an ongoing problem with the "control" of the PVC valves that are on the mkt.. Some leak, some don't. I am thinking that the use of a gennie AC Delco piece, turned out to work better than the cheapies..

That does seem to be a big problem Chuck. I have found even with Ac Delco they don't seal 100%. Splash a little oil on them and they get lazy making a bad situation worse. I'm going to order some industrial grade stainless checks for me and a few buddies. I'll take some pics of the set up when I'm done.

Kirban's has a pcv check valve that i've used for years & they seem to work pretty good. It Might help?

To be a 100% sure just get rid of the check valve. I did.

And run what in its place?

I hope you like the tech tips

You can run a nice small K&N filter connected to a hose that is slid over a gutted pvc valve to give the crankcase additional breathing.

OR

You could plug the hole in the manifold like I did. There a various ways to do that but I ran a pipe tap through the pvc hole in the manifold when I had it off the engine and used a pipe plug, no oil leaks with a plug. You can remove the pipe plug and put the grommet back in anytime and go back to stock.

no pcv valve here either, and no problems :smile:

my pcv is still there but i shoved a 3/8 plug (an old rear axle bearing from when i did the eliminators) down into the hose and reconnected , so no pcv operation and no issues
kn vent on billet oil fill and at pass valve cover , and amazingly im about the only one ive seen with those and no oil blowing out of them

Interesting, the only thing I don't like is smelling the emissions. So I like what the pcv is suppose to do. How often do you guys change your oil. I was under the impression the pcv helps to keep oil clean. Whats your thoughts on that?

over 12month period never get enough miles to require a change ,

i change before it goes to sleep , when it gets out of hibernation and then mid summer i'll change again , new filter each time

Liquid/Gas Check Valves - US Plastic Corporation i posted this plenty of times before these hold 150 psi and are available in 3/8 and 1/4 inch and are only a few bucks i replaced all 4 of my factory ones lets go guys get with the program!!!

I noticed in the Summit catalog that Billet Specialties makes a valve cover breather with a built in pcv valve and a removeable, cleanable filter element. Would a pair of these possibly do the trick? They are a bit pricey at $25 a piece.
