I beleive GM has a known service bulletin for head gasket leaks on the 3400 and it is 'hush hush'.

They also have problems with their LS1 and piston slap and again, 'hush hush'. You have to bring the car in repeatedly before they will do anything.

Or go to another dealership and hope for an honest and fair inspection.

:ninja:
Head and intake gaskets have been a problem in the 3.4L's I've seen it lots. The die will help thr tech to find your leak.

A porus engine would be a drain though
