Oil Filter Leak/Too Much Oil Pressure
« on: June 22, 2019 - 05:58:40 pm »
I just had my 74 360 rebuilt. I installed the engine, it runs great. At idle, it has about 80 psi oil pressure (new Autometer mech gauge). I noticed that my oil filter leaks. I changed the filter twice. The filter is hand tightened, gasket lubed. When I look at where the filter is attached, it doesn't look right. It doesn't look like I have the right filter. I'm using a Fram Ph 43. Before that I had a Wix filter. Is the oil pressure too high? Could this be causing the filter to leak? I have some pics of the oil filter.  Thanks

what oil you using.
I use 5 30 full synthetic.
Fram are crummy filters.
Try a K&N Gold. They also filter at 10 microns.
Walmart sell them.

Ok, looking at the pictures (after getting them sorted out  :bigsmile:) nothing jumps out as to why should be leaking. As far as the pressure, 80 should not make them leak, both my 440 and my 416 put at least 80 when cold. I use WIX filters usually, however I used Fram for years without a problem. I've read a lot about filters and while Fram may not be great, they are not detrimental to the engine.

I cannot tell from the pics exactly where its leaking, look at the adapter plate closely for any dings, burrs or damage. Also, make sure it is leaking from the filter and not the adapter plate which is gasketed and can leak.

I am reposting your pics for others to look at and perhaps provide some advice

I think it's the filter. There is oil below the filter and nothing around the adaptor plate. I hand tighten the filters when I replaced them. When I removed the filters I had to use a wrench. May be I'll try replacing the filter again and give it a small twist with a wrench. How difficult is it to replace the adaptor plate gasket?
Thanks for fixing the pics. I was having a heck of a time posting them.  Thanks again.

its possible that the filter is defective, unlikely but possible. Its more possible that either the plate has some type of deformity (scratch, burr, gouge) or that you got a piece of debris under the rubber gasket when installing it (been there done that).

As to tightness, hand tight should be all it needs. I do know guys who would put the wrench on and give them a "slight" tweak but nothing more.

remove the filter (if not already off), wipe the plate down really well and inspect it specifically where the rubber gasket makes contact, assuming you dont find anything wrong, install a new filter ensuring to lube the gasket with clean oil, carefully stick it up there and screw it on. I think your problem will go away, however if it doesn't, you have eliminated the filter and perhaps the sealing surface.

as to putting a new gasket behind the adapter plate, it isn't super difficult, hardest thing is cleaning off the old gasket from the engine side and many times the gasket comes off clean (other times you are up there with a scrapper)..

Don't overthink it, start simple and work through it one thing at a time.

The surface of the adaptor plate that the oil filter gaskets mates up with, is that supposed to be flat? If you look at the photo, it's rounded instead of flat. May be I'm over thinking this. Nothing but problems with this installation. Water leaks, now oil leaks, and brake problems.  Thanks for all your advise. I'll let you know what I find.

That surface is rounded with a very slight peak. I had similar problems on my 416 but instead of an oil filter I have an adapter for a remote oil filter. I ended up replacing that plate with an aluminum flat plate (Canton Racing), but in my case I believe my problems revolved around the think O ring on the adapter.

This is what I used

If the plate continues to leak, I may consider changing to the Canton adaptor plate. Thanks very much. As always you always have the answers.
