Head Studs, how to be sure??
 

Is there a test methode to see if the studs are not slowly pulling out?

I thought like this: put a strong small pipe over the head stud, washer and head nut - and apply torque. So how much can I go?

The studs look fine right now but when I disassembled the engine the head nuts where all diffferently and not so tight.

Thanks, harold

If it is a magnesium case I would just timesert all the headstuds.

If it's a magnesium 2.7 case, then they are pulling. 99.9%

no so tight head nuts is probably what caused the base gaskets to get squeezed out.

Sorry John, I disagree. I don't see the base gaskets as being squeezed out as much as I see them being beat to death by loose cylinders (and loose head studs).

Wayne I think you and John are saying the same thing. And I agree that the loose head studs caused the damage to the base gaskets.

squeezed, beat, pounded, whatever.

Oooh, I love it when you talk dirty! :)
