Hoping someone can suggest a good idea here. As posted in another forum here I have had the pcv valve replaced twice already and when it failed again a third time I swapped it myself. Now I followed all instructions and was HAND tightening the screws before i even got to put on the torque wrench, and the rear left screw appeared stripped. Hoped it would hold but I had an oil leak. So back to the dealer, since I am out of warranty. But to my shock the dealer said if its a stripped thread in the head, they can't fix it. WHAT!!! A Chevy dealer can't fix their own engine? One service guy suggested a machine shop before the manager berated him for saying it cant be fixed. Now I'm worried. They'll have some guy who's worke don these look at it tommorrow, they've given me a loaner, but I'm worried if a **** stupid stripped thread might be reason for them to say swap the whole head. This thing was swapped twice, so I'm sure one of the techs prior must have stripped it by over-torquing it. I'm man enough to say i screwed it up, if I had, but I was extra careful. In case Chevy says they can't fix, what options do I have. The car despite having 105,000 mile son it is in prefect shape. Any ideas? Anyone in the Orlando area?
