Fuel Injectors, allowable leakage??
Just popped up the fuel rail set it on a tray and preformed a pressure/leakage test. The pressure started at 42psi and an hour later it was at 20psi. Number 8 had one drip and number 4 had two drips in that hour.
Is this allowable? If not then I'll send them off for cleaning/flow testing.
Thanks, :flag

As I recall, it should hold pressure for about 30 minutes. Sounds like yours is in the ballpark.
Are you getting symptoms or just checking?

Just checking, I just installed long tube headers and it's running rich at idle. I'm sure I need heated o2 sensors but wanted to make sure I didn't have an injector problem to.
I did find in my How to Modify Chevy Fuel Injection book that one drip from the injector in not a problem.
