Valve Leakage Check?

[CraigG]

Hey Everybody,

I have E-heads with swirl polished valve, solid roller springs and multi-angle seats.

I tried windshield washer fluid and the inner springs installed without the spring pocket shims - the valves wept after a couple hours and puddled in the ports overnight.

Valid test? or is there a better way to check for leaks with the heads off?

Thanks Again, Craig
