I MAY have to pull the engine for some valve work on my 82 5 speed with 85K miles. I am almost sure I have a stuck exhaust valve but am trying additional chemical treatments to ensure the problem is not carbon build up. Does anyone have or know of anyone with a set of used headers or a y pipe for sale. May of well do this while the motor is out. There is not a lot left to go wrong, knock on wood LOL!
