I have heard of some problem. Is there any reason not to use lock nuts on these.....

It is annodized which is a very tough insulator. Take a bolt out and use knife or file to cut through the annodized layer, then run a ground wire to a good ground.

Just the way the guages were moving back and forth in relatation to each other, I'm going to take a closer look at the grounding situation up at the manifold. Maybe the lower temperatures are contracting something enough to lose a good ground. Thanks, John Brunke >
