This engine has and does run great, but after sitting over this past winter it slowly leaked enough water into the pan to make everything a light gray after running for awhile at about a 7-800 rpm idle.


Had an elderly gentleman who is pretty well schooled on flatheads look at it this morning, he concurred that it is BARELY leaking from between the sleeve and block. Block sealer was his suggestion...


We're gonna spin it right side up on the engine stand, install some tall hoses and fill it with water to top of radiator level and see if or where it leaks while in a static position. Kinda like it would be if sitting over the winter. Put some dry cardboard under it and keep an eye on it.



Should know in a few days if that's where my intrusion is I hope!
