Recently I performed an engine flush on my 216CI 6 installed in my 51 Chevy 3100. Now I have noticed after running the engine up to temp I get a small ammount of water slinging off of the spinning clutch/flywheel assembly and exiting out of the timing pointer hole in the bell housing. I suspect expansion (freeze) plug failure (yikes). Can anyone tell me how many are on the back of the block? Sizes? and a jobber that stocks them?
Thanks in advance


Best Regards
Will
