Head Retorque

SnoMan is correct... a good example is on the 4cyl.engines on the
pontiac sunbird and Cavalier,every one of them had problems with head
gaskets.

Yes and also with a aluminum head it is basically a must do on a
rebluid if you want maximum possible headgasket life. Also with a
luminum head it deos not hurt to recheck them again after several
thousand miles. If they are found to be okay still than do not bother
further but if they are a bit loose you should check them again after
several thousand more miles. Aluminum has a different expansion rate
than cast iron engine block and can sometimes loosen a bit with time.

What you're saying (in our above example) is that you'd re-torque
torque to yield bolts.

Not I am not because the torque values are below the point at which
bolt steel will yeild. SOmetimes afe a few heat/cool cycles, the
gaskets settle a bit and require retorquing. It is better to be safe
than sorry.

That wasn't the question.

Every one had problems? I'm on my third Cavalier with no problems at all
from the engine.

Yes it was, you implied that retorquing them would yeild bolts and it
will not unless you over torque them.

You crack me up.

No, SnoMan is not correct, and neither are you! Whether or not you
retorque the head bolts on these engines (by the way, which 4 cylinder
engine/which year/etc) will have nothing to do with why the head gaskets
fail on these engines. Obviously, you haven't had many (if any) of these
engines apart.
