I've seen FAR too many ruined engines over the past 40+ years from the use of that stuff. Leave it for the domestic engines.  |
Couldn't agree more with this, from a materials science perspective. While some RTV silicones can withstand the temperature rigors of an engine application, those tend to be pretty expensive (they use a platinum cure system). But, more importantly, RTV is not compatible, as a rule, with hydrocarbon based fluids (oils, gasoline, etc.) unless it has been modified with fluorine (flourosilicone). I really don't know of any room temperature cure system that includes this modification. I sure wouldn't want to risk it. But I'm a polymer junkie, so maybe I over-think this stuff. Good luck.
