SilenceboneSupra · 01-14-2008, 07:55 PM

hi, i noticed that the engine had milky oil so we dissambled the engine and found the BHG, the engineblock looked allright no cracks at all! we cleaned the engine inside and out completely and retorqued the engine

.....
after done with the engine after a few days again it had milky oil

.......
anyone have any idea why i still get milky oil in the engine
we are sure there is no cracks on the block and i dont think the new HG could of let go in just a few days ....
any tips would help(i think)

If your head wasnt resurfaced i could still be leaking

My thoughts also.

You never mentioned the head.
You have to have it machined because the alluminum
expands, contracts and warps.

This would be my gues as to why you still have a bhg.

See the block is cast iron and the head is alluminum.
They both have different stress levels.
The cast iron will never warp enough for your eyes to see.
THe alluminum will but you'll have no way of knowing how much till its machined.

I would also incorporate ARP hardware and HKS mhg.
Probably a stopper. But none of that matters if you don't have atleast the head machined.
