head lifting?
 

I have a b18b and I think the head is lifting off the block underboost. I'm only running 7psi, but when I rebuilt the motor I reused the headbolts with a new head gasket. I'm swaping a b16 head, new head gasket and arp head studs onto it soon so i'm not too worried. But everytime I drive the car, I noticed there's oil all over the block comming from just under where the turbo manifold bolts to the head and it's running all down the front of the block.

Would this be for sure sign that the head is lifting? I couldn't think of any other explainations.

if you have pressurized coolant (if its getting bubbles) then youre head is lifting.

How do I tell, take the car for a drive and look in the resevoir?

check to see if your overflow tank is completely filling up...this is a good sign that something may be wrong with your headgasket.

I checked the tank and it's bone dry. Lots of coolent in the rad though.

hmmm doesn't really sound like a headgasket to me if your overflow isn't filling up.

Re: head lifting?
 

if its a leaky headgasket, your car will overheat if in boost.

There's oil spraying out around where the head meets the block in the front. It's comming up under the head flange for the manifold and I can see it around the top. It looks like a lot of oil, but the level on the dip stick hasn't moved.

Any ideas?

if oil is actually seeping out of the seam between the head and the block, definitely pull the head.

Have the surface checked for flatness, and throw on a new HG.

could be blowby too tho, owned rings.

my bet is the head bolts are stretched and they arent holding the head down enough..

do u ls/vtec head swap and clean the block, see if the problem continues.

also, is the head area around the valve cover dry of oil?
