So, today was the day to wake Jaws up from hibernation.
There was good news...no evidence of mice for months now. I vacuumed up the stink bugs that had made their way in, and took care of some little chores, including replacing the turn-signal cam (which gave me a chance to play with my recently bought steering lock plate compression tool) and mounting the Ragusa cruise controller on the old stalk. Then, I pulled off the air cleaner to check for mouse remains and to install new spark-plug-wire spacers as a preventative against spark induction. I replaced all the vacuum hoses with expensive orange silicone hoses that are never supposed to get hard and brittle. Everything looked fine...
...except...
...for that little green puddle on the top of the intake just to the left of the thermostat housing. GRRR! I've had that housing on and off several times, over the last coupla years, and each time I have installed it with the typical fiber gasket with a layer of high-temp silicone gasket sealant.
I recall reading some advice from Matt Colie (I think) that suggested silicone on both sides is a mistake, because it causes the gasket to shear with thermal stress and then leak. Is this my problem? It was never a problem before, but it was always an iron housing on an iron manifold before.
What have you guys done to seal your thermostat housing? I do NOT want to tighten it down much, and risk stripping the threads in the manifold. I'm strongly tempted to install studs as it is.
