Found out that tstat that was in was nowwhere near the right one the new one was a 2 - 3 piece if you count the gasket on top of the tstat. basicly missing the brass base and upper gasket. the bypass was allways open and when under load or high rpms the water flowed to fast to pickup any heat like no tstat at all. that is my assumption. Now on with the front crank seal started  leaking oil will it heal itself?  if it is cork will it swell back up and seal? it doesent seem to be leaking as much as when I first started it up.  been setting for several years.
