Water pump leaks

[Bruce B.]

I have a 62 Corvette with a Ramjet 350 crate engine with a T10 4 speed and use a stock GM water pump. I have replaced the 4 water pump gaskets a number of times but after a few hundred miles I get water seeping at the pump gasgets and have to retighten the bolts. I use FelPro gaskets, Permatex #2 and torque the 4 bolts and it still developes leaks.
Any remidies for this situation?
I'm heading to CA from Ohio and need to eliminate this situation.
Thanks,
Bruce B.

Re: Water pump leaks

The motor mount surface where the gaskets line up is a prime area of leakage.. On mine it was quite pitted. Also try using a high temp. RTV on the gasket surfaces and the bolts.

Bruce, Use an appropriate thread sealer on the mounting bolts. They pass through into the water jacket and that is a likely source for your leak. Regards, B. Myers
