Hey guys,

i was just doing an oil change, and i noticed a leak..... it appears to be coming down from the head area and collecting on the oil filter/oil cooler lines.....

I did a cam/headstud install about 3 weeks ago, but im not sure that caused it? i have resealed the valve cover gasket very well, and it's still leaking

Here is a picture of the oil drained, if it is indeed coming from the head gasket, it might have coolent in it... can you tell?

Thanks

Did you use hi-temp silcone around the cam seal? If not, your oil leak is probably coming from the cam seals. I had the exact same problem as you.

 

No i did not, i didnt know where to place it........... what was the path of the leak? because i just had the cam gear cover removed, and it was 100% oil free ........ so im guessing a cam seal leak would run down the that side of the engine.... correct?

 

compression test in..... 154 155 157 150 (using a harbor freight comp tester) ...... Could it be the head gasket?

 

spark plugs... if it helps?

 

Pull the upper timing belt cover ( cam gear cover) an see if you can see any oil around the the cam seals.

 

I just had the cover off, i didnt inspect the cam seals, (can you see them with the gears installed?) , but i also didn't note any leakage in that area...... I assume it would leak straight down.....

 

i just found this:


could this be the issue......... Is the threaded area of the block have a passage way directly to high pressure oil?

 

What you have hear is a common problem, but that seems to be quite abit of oil depending on the time it took to leak that much. Replacing headstuds one by one seems to be the problem most of the time and it usually causes the oil to leak out the back of the head more so than the front. The advice I can give you is recheck the headstud torque values and make sure they are good. If they are all at the same value you will probably need to pull the head off check the flatness , clean it up and replace the head gasket. If you do replace the head gasket I recommend purcasing a good aftermarket gasket (Greedy, PowerEnter, HKS, ect.). I am not a big fan of the stock head gasket becaues of this, just my opinion.

Don't get to worried yet, keep an eye on your oil and keep off the boost until you truly determine if things are mixing. Usually they don't get mixed but that is quite a bit of oil even if it was for a couple of days sitting there becuase under boost it would leak alot more.

As for above, you can hand tighten the stud into the block but use a allen wrench and get it tight. This is where most people get mislead, it has to be tight (not finger tight) otherwise they have a good chance in loosening. I recommend 85ft lbs as well on the nut with cycling.

 

This is your anwer here .
