I've actually had motors stop weeping, doing this on the dyno. Right or wrong....works for me.

On my sbc I didn't spray coating as I was informed by many not to. If you had good luck spraying then I will on next rebuild for piece of mind as I run alot of nitrous and feel leary of not coating them. Thanks for the info.
