edelbrock water pump ??

[scotts4]

I have a edelbrock waterpump on my truck . it was put on when i did the motor about 3000 miles ago . I got the pump new . It keeps blowing out the gasket for the rear plate on the pump . when i replaced it last i cleaned the old gasket off with a scraper and put some gasket sealer on the new one . now when i hit high rpms it leaks . any one have any problems like this or any ideas . The pump is still under warrenty but i have to send it back to them and they will send me a new one . I hate to send it back for just a gasket . anyone ?

Put a straight edge on pump and cover and check to make sure it is flat.

Yeh, I've got one on my Ty and I haven't seen any leaks. Can't see why it would leak unless it's warped, or the surface is not smooth.

when i put the new gasket on it i put a straight edge on the cover and the pump and they looked good . I just ordered a new pump and when i get it i will send the old one back for a refund so i hope it was a pump problem ? thanks for the help

Yeh, I guess the other possibility is that the block surfaces are warped or rough. But they're such small surfaces ? Maybe there's a crack somewhere ?

i have the same pump... polished aluminum. never a problem.

try a system pressure test.

its not leacking at the gasket from the block to the pump . its leacking at the gasket on the back of the pump at the plate .I have done a pressure test and it does not leack only at high rpms ? If i pressure test it and rev the motor it will start leacking .
