Default Oil Leak Passenger Side Replaced Oil Cooler Ring

So I have a leak coming from the oil filter area and I thought it was the oil cooler gasket. I did replace it and it is still leaking. It is slight and seems to be only when there is a good amount of pressure. I looked at the oil pressure switch and it seems to be dry. I wanted to know if the oil pressure relief valve would also cause this or where else I could look.

I would check the hoses/ aluminium coolant lines in that are. Also, the rear valve cover might be leaking or drive axle is seeping through the clamp in the boot and spraying forward.

Right on Im going to check the valve cover to see if I can spot the source of the leak.

Is there a way to check the rear valve cover without removing the upper intake? I tried looking for a leak from the top and couldn't see much but the oil splattered on the filter, control arm and wheel well

Oil travels down due to gravity, your best bet would be looking from the bottom.

Default Re: Oil Leak Passenger Side Replaced Oil Cooler Ring

Ok I'll try to look from under maybe tmrw morning and see. Let's say it is the rear cover. Is it better to replace the gasket or just use RTV? I heard RTV might last longer. Also u don't have to replace the cover itself right?

This is all I can see. Cant really spot the source of leak. I can only assume it is the top left corner of the rear valve cover that I cant see since I don't see any leaks from any where else.

Default Re: Oil Leak Passenger Side Replaced Oil Cooler Ring

The driver side had a tear before and the grease from the axle is dark grey. This is definitely dark brown and looks like oil.

Im pretty much ready to buy the parts for this job I just don't know if I need anything else besides the valve cover and seal. I answered my own question I guess those spark plug seals come with the new valve cover.

So the main help I need is to know if using only RTV is a good idea or should I just replace it with the normal gasket and just do this every 100K or however it takes.

Hate to say it but I don't think the rear valve cover was the issue. The gasket was still good and I am really lost on what this could be. The only other thing I can think of is to have the car up on ramps and have some one rev the engine up to hopefully spot the leak. But besides that I am completely lost.

Your oil cooler mat be cracked or warped. But....
That could very well be old axle lube.

Clean the area thoroughly, Make sure you get all of the fresh oil.
See if oil could be leaking onto the axle and getting flung around.
Check Have someone run the car at 2000 rpm for 5-10 sec. while you observe the area.
If you don't see any oil spray out then the look for oil seepage and/or squish the CV boot to see if anything comes out.
If you see the spray coming from the cooler then its likely cracked or warped

PS, there is a slight chance the Oring got twisted upon installation and/or you did not clean the reassess for the Oring thoroughly and so the Oring is not seated properly.

When I got some exhaust work done I had the shop replace the O ring for the oil cooler and then I did the job myself again thinking they didnt do it right. I took my time and made sure that O ring was in there and cleaned the mating surfaces thoroughly.

So I'll try observing the parts you mentioned next day off hopefully I can find it.

Its always hard to comment because you never know how mechanically savvy someone is. I was thinking about this and structurally speaking, the line fittings on the cooler itself could be the culprit. Personally, oil leaks drive me bananas. I am a firm believer in the "if oil is getting out, dirt is getting in" principal.

Default Re: Oil Leak Passenger Side Replaced Oil Cooler Ring

Hey guys I know it has been a while but I thought I would update to see if it helped anyone else. Last time I thought it wasn't the rear valve cover because I kept seeing small amounts of oil landing on the control arm and filter. It was reduced but I just assumed my issue was still there and just hadn't leaked a lot yet.

Well anyways after my kind of giving up for a little bit and then checking it again I noticed there were no new oil drops and the little bit of oil from before had dried up. So what I'm thinking is that the oil I must have seen was a little bit of left over from splattering everywhere and it happened to make its way down.

So long story short Im sure this issue is solved and the leak was more than likely the little bit of RTV at the corners of the valve cover that broke down due to too much heat.
