Well, I finished putting my ls/vtec together, and after starting for a few minutes, there's an oil leak. The leak seems to come from the back of the head, kinda under the vtec oil line, where the head meets the block.

After realizing this, I took the head off, and check the head gasket (which was new OEM), and didn't find anything. Then after putting everything back together, it still leaks from the same place! Any ideas?

The only think I can think of is that I was using GSR ARP head bolts torqued to 70 ft lbs with moly lube. Should I try torquing to 85 ft lbs with 10W-30?

 

Head gasket incorrectly installed? Usually an oil leak at the rear of the head is due to an improperly installed head gasket. You can tell without taking the head off. There is a silver tab on the gasket, it should be visible on the tranny side of the engine, towards the front.

 

Ja you put it on upside down.

 

what head gasket is it made for, LS?
