RJC Biggie. Anyone use it?

[Mr. T-Type]

I'm currently having an oil pressure problem at idle. This claims to increase the idle oil pressure. I just wanted some opinions before throwing money at my car.

I put the biggie adapter on the same time I installed KB booster plate. Went from 10# idle hot to 18#. So one of them works. Or a combination of both.

I would say the Kenne-Bell plate got you the 18lbs. Mine did.

Got the biggy RJC on the GN, works fine but the filter discussion always gets me cornfused.

Do a search on "biggy" oil filters.

If you want to find out if the biggie gizmo will help you, before you send in your $45, just install a purolator L30001 oil filter on your engine. This filter is larger than what the "biggie" will accomodate. If it improves your oil pressure, by all means, let us know. I've been using the L30001 on my car for 30,000 miles with no problems.

John.

Someone was using a larger filter a while back. I don't know if it was the L30001. Some guys said you had to cross-thread the filter??? Do the threads match on yours?

Thanks

The L30001 has english system threads, 3/4"-16.

The stock buick filter adapter base is METRIC, M18-1.5.

Threads might be similar enough to "sort-of" fit or cross thread, but use it at your own peril.

The RJC Biggie adapter is really the "right" way to install a larger filter. It adapts to filters with an english 13/16"-16 thread. Although most people use the RJC with a Delco PF24 (or equivalent filter), Baldwin's B9 filter has the correct threads and is 25% longer than the PF24 .

The Baldwin B9 is about the same size as the Purolator L30001.

IMO, the $35 or so it costs to buy the RJC adapter is cheap, and is the "right", safe, and reliable way to install larger filters.

I just want to know if it does what they claim before I drop the $35 on it. I know its cheap, but if it doesn't do what I expect it to, I would rather have just spent the money on the Kenne Bell plate.

You will probably get more psi increase from a K-B plate, or equivalent. Larger filter (more filter area) will yield less pressure drop across the filter, and less liklihood of the bypass valve in the adapter base opening and bypassing debris, but the net increase in oil pressure won't be as much as with a booster plate.

is there a link to where I can buy this booster plate?

is there a supplier somewhere to purchase the baldwin B-9 oil filters? thanks

I bought mine years ago direct from Kenne-Belle (909- 941-6646), who I guess originated it. I suspect you can get the equivalent from the 'regular' buick vendors like ATR or Cottons, but I don't have any specifics.

Search at Baldwin's site ( http://www.baldwinfilter.com/vendor/index.html ) for a distributor near you. They sell through thru industrial & commercial distrbtors, not thru consumer retail stores.

Blow Test on the Baldwins

I bot a biggie adaptor from Cottons about three years ago. Since the discontinuation of the PureOne filter, I've been searching for a comparable filter that has an effective anti-drainback feature. The Purolator L20033 is the closest I've found that passes the blow test for the anti-drainback. Does the Baldwin have the anti-drainback, and if so, does it pass the blow test?

Kind of off the subject, but if you are having a problem with low oil pressure, it is probably your bearings and not your oil pump or filter. pull the pan and change the bearings and be done with it, you should never put parts on your car to increase the oil pressure, fix what is really wrong!!!


Flame suit on.

I'm planning a rebuild in late january (assuming the finances are there). I just want something to get me buy for the time being.

As noted somewhere above, the threads are a little different on the L30001. To use the 30001, it does not damage the nipple on the oil pump. Just turn it on and tighten normally. I've been using it for at least 15 oil changes with ZERO problems. The filter is larger than the one the "biggie" accomodates. I wouldn't expect you guys to do something that wasn't "correct".

By the way, the booster plate will probably be much more helpful in increasing your oil pressure. Also, if you're using a light oil, you could mix in a qt. or two of a heavier weight oil when you change your oil. I use 10 40 and mix in 1 to 2 qts of straight 50 wt. Works for me!

Make your own "Biggie" adapter. I went out and pulled a oil filter adapter off of a small block Chevy. Then cut the the aluminum base off of the adapter. So the only thing that you have left are the threads. Then I ran a M18 tap into the center of the treaded piece. Then red Loctite it on to your your factory adapter. It will take the same oil filter that a Buick 455 will take.

Since the Baldwin B9 is intended as a larger cross-reference to the Delco PF24, yes, it does have an anti-drainback valve.

I've actually found the ADV on Baldwin's to be more consistent than AC Delco filters -- out of about 10 Baldwin filters purchased, they are all extremely tight when I try to blow air into the center air (with my mouth, not compressed air, which could damage the filter).

For me, ACDelco filters have an occasionally "weak" ADV, at the rate of about 2 or 3 out every 10 filters. It had gotten to where I would blow into the filters before picking it off the shelf. Must have been an odd sight.

I now use only Baldwin filters on my chevy Blazer, too.
Note: Baldwin B35S is the exact size replacement for the Delco PF52.
