oil leak in a unexpected place?

xreaction122 · 10-11-2008, 01:44 AM

ive been losing bits of oil and i was looking around the engine bay for possible leaks.

and i see oil saturated in the middle of my exhaust manifold

somewhere between cylinder #2 and #3.

i checked the valve cover but its sealed tight and no sign of leaks at all.

any ideas?

The most center exhaust stud on the bottom row actually acts as a plug to an oil galley in the head. If you are missing this stud or it is not sealing correctly, you could get a leak towards the bottom center of your manifold.

I have this problem also. I have asked in the past about any studs entering the oil gallery and no response and the service manuals do no mention this. Are we sure of the center studs entering a oil gallery? If this is so I did not seal the studs with sealant before install and that could be my leak also. Thanks

Does anyone else have a answer to the question if the exhaust manifold studs are backing into a oil or water jackets. Thanks

Don't bump a thread.

update on the oil leak.

i picked up a set of OEM studs for the exhaust manifold and some sealant.

so i cleaned off the oil traces on the exhaust manifold and drove around for about 10 mins..no good. its still leaking..i had to fill about another 1/2 quart today.
time to get it checked out?

aaronspeed · 10-14-2008, 11:32 PM

No I did not miss the post but the answer seems not to be correct so I was checking for another response. I pulled a head out of my stock and none of the studs enter a oil gallery that I could see. Thinking about it instead of asking would have made more since. That was my mistake. Why would a manufacture have 60psi+ pushing against a exhaust stud.

DsmJapSpyder · 10-14-2008, 11:42 PM

i would say time to take it to a repair shop...

I think it's time you took a picture for us. There is absolutely nothing that would leak that far up unless it's the valve cover, freak accident with oil feed line, or that stud.

Those threads and stud can definitely withstand the amount of pressure going through it.

xreaction122 · 10-15-2008, 04:18 PM

here ya go.

if you look closely,there's oil above the exhaust manifold gasket also

xreaction122 · 10-17-2008, 08:34 AM

i apologize for bumping the thread but any comments on the update?(picture)

it feels like im losing more and more oil everyday

TurboT91 · 10-17-2008, 08:57 AM

Have you checked your PCV valve lately? I know you said the valve cover gasket is good and completely sealed, but maybe you are building crank case pressure while driving and that is causing oil to leak past the valve cover seal. Were there any nicks in the valve cover/head mating surfaces when you installed the gasket? If so, did you use a little RTV?
