Replacing a water pump on a 454	John	3-12-06
New to me 85 Itasca w/454. I replaced the waterpump and shortly after developed a small leak at one of the gaskets. Had a mechanic replace the gaskets and pressure test and figured it was fixed professionally. Drove it about 25 miles and a gasket failed again. Should I wonder about the pump not being square or just keep replacing gaskets? A real pain to do by the way. Thanks. JB

Thanks for the story. Chevy dealer is trying to put the fear in me that maybe it can't be fixed-gimme a break. By the way, I'd figure out a way to get off the 666 mileage. A buddy and I were taking our kids cubscout camping last summer. I happened to notice that his odometer was at 66,666.6 when we pulled out. Within 10 minutes we had a flat tire. But get this: Later that night our camp site was hit by the tail end of a tornado that layed a 40 pine tree over our tent-thankfully we were gone by that time. JB
