Reply To: My EVAPO RUST experience

[Jim Follis]

Thank You both Ed and Greg for your reply

The head is already at machine shop . The water passages that are visible look dark , not rusty. The gasket was free and the stud was tight all the way up.

I have always used soft or distilled water with Napa cool or no rosion or similar rust inhibitor since the complete rebuild 6 years ago 650 miles. I did not re torque after heating up at Napa. Which surely would have been good to do. Will carry torque wrench in future.

I have removed broken studs and cleaned all threads by running tap all the way in on all 21 holes. Will be sure to use anti seize which I think I used before?

Thanks Again, Jim
