the rear hoggs head on my toyota has one broken stud and another about to go. its leaking badley. the housing itself is not damaged assuming the broken stud can be extracted. i know this is a common problem for these trucks im just curious if anybody had any idea of how much money its going to take to replace that gasket and fix that broken stud if a shop did the work?? i also need the drivers side valve cover gasket replaced its a 3.0 v6. just curious any mechanics out thare maybe you could give me a ballpark figure so i know what to expect when i go to the shop? thanx!!
