Re: Exhaust Manifold Heat Riser Spring

Still futzing with this $&#* spring. When the engine is running it bounces between partially open and closed making the engine erratic, of course.

The spring is from Max, wondering if it is not getting enough heat transfer from the shaft of the valve. I have the radiator out now as I work on the cleaning up the front clip to soon reunite with the rest. SO I can't try out any options but clearance to this valve will never be better so want to get your opinions to take my best shot at it. I all can think of is to better crimp the shaft around the spring tang to get more heat transfer, but wondering if anyone else has had challenges getting these to work? Seems like it should be easy, assuming I got the right spring from Max.

Any suggestions?

thx
