Where is this oil leak coming from? (pictures)

Pbforlife254 · 01-25-2016, 05:12 PM

Wondering where this leak is coming from. I recently changed my valve cover and cant see what gasket would be looking for this. If you look between the intake ports is where you can see it. I cleaned the oil off then took the pictures. It wasn't much but just cleaned it off to see if it comes back.

Blow-back from oil filter housing gasket?

Pbforlife254 · 01-26-2016, 07:38 AM

When I changed the valve cover gasket I changed the housing filter gasket as well

Then maybe it's just old staining from a previous leak...

Pbforlife254 · 01-26-2016, 12:55 PM

I cleaned it off so I'll report back in a couple days or so.

Did you also changed the gasket for the oil cooler? Mine was in bad condition when i took it off.

Not sure if I have the oil cooler on my car? Any easy way I could check

Pbforlife254 · 01-27-2016, 03:41 PM

I take that back I do have the oil cooler. Anyway I can check to see if that is leaking?

Its the front part of the Oil Filter Housing.

Pbforlife254 · 01-28-2016, 08:33 PM

I don't think that would cause oil to be all the way by the Intake valve s

Check your PCV valve for blow by coming from the valve near cylinder 6. The o-ring could have set causing a leak. Mine had the same issue. Replace o-ring, and no more leaks.
