Lets start this off with good old reminder. . . . Everybody go get oil changes. I finally did mine for the first time since I bougth my "metzersmit" and I have no skipping in my high RPM's the car is running great.

Exhaust is an issue when you running a header. Do i need to hurt someone at kings muffler in OKC for my 14 mm nuts falling off my racing beat muffler to pipe flange five months after my exhaust was built. . . or is this a constant issue with the angle of the 1980 muffler because it hangs?

 

Never had the nuts fall off the final flange. I'd say someone forgot to torque them properly.

Only case of spontaneous nut ejection I've ever had on my '80 is the nuts that hold the ACV on the intake; seems that the valved air pulsations can work them loose over time.

 

when i had a T2, the turbo would loosen up, it turned out that the lock tab it came with was there for a reason....

or you could use the FD locknuts, JE10-40-355, they are oblong at the top so they wont come off, ever

 

someone just forgot to tighten the bolts back there, sometimes you get a mechanic with string bean arms.....
