condensation on plugs?
I just finished firing my BBC 496, ran great! set the timing checked all the usual thingsevery thing seemed fine till the next day, I pulled a plug and it looked like it had water on it, I retorqued the intake (which I had milled to fit) checked the oil for water, it was fine (drained and changed filter) Started it up ran fine, next day water on the plugs again? Presurized rad, no leak down. Is this condensation? or a bigger problem?
:? thanks for any advice in advance.

It could be condensation. How long are you running it? Are you running it long enough to bring the oil and coolant temps up to 180-200 degrees, if not that can cause condensation. I've had it happen before when taking off valve covers to check lash.

I did bring it up to temp in the morning to set timing. But started it up later that night for a short time. Should i try bring it up to temp, let it cool then check the plugs? Then check them them again the next day. By the way its on all the plugs.

Just curious what is the ambient air temp in your area?
Cool moisture ladden air will condensate on metal, especially this time of year.
It might be what your seeing.
Run the motor till you get it good and warm 180/200ish, let it cool till you can work on it without getting burned - then check the plugs.
That's what I do.
