As I grumbled about in the "What did you do to your truck today" thread, my new water pump came with a torn gasket in the bag. I have to wait until tomorrow afternoon for a new one. The old one was super-hard, really stuck to the front cover, and had RTV red smeared on the pump side of it. It occurred to me that RTV, Hylomar, Permatex Aviation Sealant, Form-A-Gasket, etc. could be used to seal the machined surfaces and eliminate the gasket entirely. Has anyone done this successfully (i.e. no coolant leaks)? I've decided to wait for the replacement gasket, but still wondering about other options.
