I'm hearing a tapping noise and only when the motor is fully warmed up or driven 4-5 miles. Sounds like it's coming from the right side valve cover to me. I've tried all the oil additives but no joy so far. Any way to check the exhaust gaskets without pulling the manifolds off?
Exhaust leak no idea other than if you can see a lack of gasket in A part of the sandwiched pieces of metal. Or can feel hot air coming through it or throw some powder in the area suspected and look for an area of the cloud that obviously being pushed by a leak. Also be warned according to ATF 70% of powders are flammable, even confectioner sugar and flower. But a little flower isnt flammable by a lighter, just checked but exhaust is around 1400 and lighter only 1200 and everything has specific flash point ranges so idk. Honestly not that hard to swap gasket. Do what was suggested to break them free easily. Keep your hand in a safe location so if they do break u dont bust your hand!
