Oil Filter Adapter problem

[Jeffyboy]

Hey guys,

A little background first: For a long time (maybe since buying the truck - not sure, though), when I floor the gas, the oil pressure drops from 50-55 psi to 30-40 psi and works it's way back up slowly. Some people on here have thought it's due to the bypass spring being too weak and they suggested trying a non-bypass oil filter adapter.

I just got done installing the Jeg's non-bypass oil filter adapter, but I have a problem. I also have an oil cooler and with the bolt torqued down, there is space between the oil filter adapter and the sandwich adapter for the oil cooler. I can actually push it up and down a tiny bit. This is obviously not a good thing. Any suggestions?

I've heard you can tap the stock adapter out and put a 1/4" pipe plug in to accomplish the same thing. Is this true? Can I leave the bypass spring and everything in place, install the plug, try it out, and then just remove the plug if it didn't make a difference? Or is there a way to install a stiffer spring in the adapter?

Thanks,

Jeff

Well, I took it all apart to see if I had something in wrong or something like that. When I took out the sandwich adapter bolt, the threaded insert in the oil filter adapter came out with it. I put it back together and compared the two on the bench top and the Jeg's one has a much longer threaded insert than the stocker.

I cleaned the bypass port really well thinking maybe something was gummed up. Maybe I'll just put it all back together and see what happens. Won't be able to test it until Spring, though.

Also, is there any kind of gasket for the filter adapter? Mine didn't have one and my SBC rebuilding book didn't mention it, but the Jeg's adapter came with an O-ring, so it made me wonder.

Thanks,

Jeff

In case anyone cares, I called my buddy at the local Chevy dealership and he could have a new adapter to me in a day, so I went ahead and took apart my stock one and plugged the bypass. I got everything put back together tonight, so we'll see how it works come spring.

Well, some of us care. Too bad we have to wait for the results in Spring. I was continplating the same set-up. I have a Lt1 and wanted to put a remote filter and a cooler in the system. I am sceptical in doing so. I think I may use a sandwich adapter with a temp switch for the cooler. Can you talk to your buddy on which would be the best adapter for a LT1? If you would, get a part # for me. Thanks and wish you well on your adventure.

Sorry Jeff, we do care. I would have posted earlier but this thread didn't come up when I hit " new posts". I think the old site way for new posts worked better. Anyways...Sorry for rambling...
The adapter you got from jegs that fits too loose I would not use. I would be afraid that it will leak and burn up your motor. there are supposed to be gaskets for the filter adapter. THe piece that fits in the block I believe has a paper gasket and the pieces tat go on the outside have rubber o-ring like gaskets.
Once you get it together make sure its correct and don't leak. Can't see you toast a motor for the price of a 50cent gasket.

On my filter relocater I had one of the Summit ones. It had red rubber hose that transported the oil to and from the filter. They swelled soooo much that I was afraid they would burst. I ended up haveing Napa make me some hydrolic hose to replace the rubber hose. 2500psi hose w/hydrolic ends worked great. Never had a leak. Never swelled at all - had no issues. The only thing I noticed was that my Oil pressure seemed to increase- at least by my pressure gauge.

I miss a lot of new post also.

I think there's a little confusion with which adapter I'm talking about. The part that bolts to the block is what I plugged the bypass in - it's what your oil filter screws onto when you don't have an oil cooler in place. It was the Jeg's version of this piece that comes without the bypass valve, but was too long so I couldn't use my oil cooler sandwich adapter that goes between the oil filter adapter and the oil filter.

My buddy at the dealership said his computer told him it goes on without a gasket. The oil filter would seal around it anyway, so I can see why this is the case. The oil cooler sandwich adapter does have an o-ring on it so it will seal to the block.

I'll keep you posted with what happens. This has been going on pretty much forever and was fixed temporarily when I put a K&N oil filter on. Then I got the oil cooler and the problem came back even though I'm still using the same filter. The theory has been that the stab of the throttle is moving a bunch of oil really fast and opening the pressure bypass on the oil filter mount. So we'll see if plugging the bypass will help or not. If it doesn't, I might try taking the oil cooler off and running it to see if the problem goes away again. If not, other research is pointing toward excessive windage being the problem and running only 4 quarts of oil might help. So we'll see.

Thanks for the replies.

The threaded nipple (that your filter would screw onto) on the Jegs adapter is to long to work with your oil cooler adapter? If this is the case, you can cut that nipple off shorter. It is a standard pipe nipple. If it is bottoming out in your cooler adapter, just cut some of it off. It won't hurt anything.

If this is the problem

I just click on New Posts under user cp on the upper left hand corner and read all the new posts. Every time I log on that is.

[grimpuppy]

But if you happen to leave that page for some reason before you read all the new post, I haven't found a way to get back to it without using the back button several times. If you click on new post again, I lose all of them I didn't read yet.

Keep us updated on the oil problem. Your right the piece that goes inside tht hole in the block doesn't have a seal. The oil filter seals it. I thought the oe filter/cooler asembly has gasket in it but I could be wrong.


As for the posts, Grimm is right if you leave without hitting the back button there gone. Frequently I will log on to the site for 4-10 minutes. Not long enough to read more than 1 or 2 posts. When that happens all other new posts are no longer new next time I logg on even if I didn't read them yet.

Yeah that is true so I open the new post page then every new post I open in a new tab or a new window and keep that new post one open. But it is a pain.

[grimpuppy]

That's what I do also. I end up with 10 tabs open sometimes. Like when I search past threads for an answer for someone.

Thanks for the replies - I thought about cutting some of the length off the Jeg's adapter, but didn't have a nut that size to clean the threads up with, so I went the route of plugging my stock one. I'll let you know how it works out.

By the way, it's amazing how thick 15w40 oil is in a 35-40 degree garage! I'm really surprised it even moves through the engine.
