+1.. head gaskets are fairly cheap and you could do all the work in a day...

if your planning on going with a cam or something later.. then yes i would go ahead and upgrade to a better head.... if nothing else buy some stock ls6 heads or something.. if you have the money go for some ported ls6s or 5.3s... and if you are looking to get some nice heads, go for some AFRs or TFPs

Damn i hate it ... the last 8tkm i drove with the Mobil1 0W-40, i hope the oil wasnt to runny. Is somewhere in the world wide web a guide "how to remove the cylinderhead" ?
I restore my old buick.... and when i see the LS1 engine in the camaro.. damn is this tight

I agree. Clean the area really good and drive for a few miles. Could also be a rear main gasket. When it is running do you smell burning oil? Can you see smoke coming of the exhaust manifolds?

I'd make damn sure of where it's coming from before I pull the head.

Hey thanks to everbody who helps me! really friendly this Board. Today i try to clean the head. Than i will watch with a mirror behind the corners from the head to see where the oil comes.
Can anyway the Mobil 1 0w-40 the cause to be?

I have a problem with my dipstick tube leaking on an LT1 on that same side as your leak. Is the LS1's dip stick on the same side? I bought a new TB and decided to not run the pcv hose to the TB and just put a small breather on the valve cover. Now because I am not sucking the crank case air out of the motor, pressure builds and the dip stick tube is one of the spots mine tries to vent from and it gets all over the block and starter. I need to put a bigger breather on it but some food for thought anyway.

i have heard of people actually running too thin oil..

try some pennzoil plat. 0-30 or 5-30..

**0verkill** · 02-01-2009, 09:59 PM

just put 10-30 i have sean seal start leaking with thin oil also. i would bet the cover.

The rule of thumb is start from the top of the motor and work your way down. Valvecover gasket are extremely easy to do and cheap at that. Also take a look around the cam sensor and the oil pressure sending unit, chances are its not coming from there, but it is possible. Clean everything up and go drive and I would run a little thicker oil, 5-30 should do the trick.
