Hi Bill
In the 'Whatever works Tradition':
After a 'required' thermostat replacement change, I once had a
thermostat housing bolt refuse to tighten on an E-Type Jag I had in the
70's. I also discovered the threads in the head were stripped. As a
temporary measure I used a plastic sliver from a soda bottle (used as a
shim), with a fine coating of aviation gasket cement. Since I never had
a problem again with it-that was the solution- I crossed the country (MD
to Calif) twice with that car, once in winter, once in summer.
As far as procedure, I cleaned the thread hole with alcohol and Q-tips.
Applied the gasket cement with a Q-Tip (any cotton intentionally
remaining acting like 'fiber reinforcement'. Slid in the plastic sliver
(and I mean sliver). Started the bolt- the sliver acting like a
heli-coil. Certainly would prevent metal drilling. Also uggest 'drying
time' for the aviation gasket cement. When we use this stuff on cork
valve cover gaskets on the airplanes, we've found 24 hrs before use of
the engine makes a much better seal. Valve covers on aircraft are in the
veritical position, most weeps are thus, not suprisingly, at the bottom,
as would the water pump application.
