Well, took my truck in because of a dang noise what sounded like an exhaust leak on the passenger side of the engine. Changed out my plugs along with a new header gasket. Well, upon removing the bolts the end bolt toward the back of the engine is stripped. The person that had the truck before me must of stripped it putting in the headers. The mechanic stated they got the bolt in as tight as it will go, but it will need to be fixed, either to take it to a machine shop or replace the cylinder head. Any ideas out there, or has anybody had the same problem and how did you fix it?
