Hey Scotty, thanks for the awesome you tube videos. my 88 chevy s10 2.8 L v6 has a leaking valve cover. 8 years ago as a newbie mechanic I changed gasket to try to stop the oil leak and in doing so I over-tightened some of the stud bolts. few them stripped in the bolt holes i think--or maybe they were already stripped from prior owner and that why was leaking in first place. So some of the bolts just keep turning without tightening and it stripped in the holds. Truck leaks about 1 quart oil every 600 miles - messy looking engine on both sides and all around - smokes sometimes too. Is there a way to rethread or get the bolts to be tight? Also what about trying more expensive thicker rubber coated steel gasket plate instead of standard gasket? OR trying high temp gasket sealer instead of a gasket or with a gasket? Some people say put lock tight red on the stripped holes and studs? i see only one Thread Repair Kit on the market product. Reviews are mixed some warn the stuff sets fast so act fast. mixed reviews on that stuff. should i try longer valve cover clamps to help distribute pressure. Please help and share any advice you have on leaky valve covers in general? I guess I'm still a newbie still learning. What i thought was an easy project turned out to be a mess.
drilling and tapping the threads is the only real fix. But you could leave em alone and use permatex the right stuff gasket maker in a can and that often will stop leaks
