my 300ex has an oil leak between the cam cover and the head and when i checked it out i found 3 bolts that hold the cam cover on were stripped out.:icon_cussing: could i use a helicoil kit to fix them or should i just replace the head? thanks in advance.

The stuff that I have--made by Permatex--says that it will repair and hold in spark plug threads, so it must supposedly be suitable for that kind of heat. But I have not had much success with it at all. Best use helicoils and the job is done right. OTOH, in places where you can step up a bolt size-say from 7 mm to 8 mm, you could try to redrill to the proper size for an 8 mm tap and tap the hole to fit the 8 mm bolt.
