Ricko the valve covers were replaced after the rebuild because the aluminum ones put on during the rebuild cracked around the bolt holes. I made the mistake of trusting my 22 year old grandson to swap them out when I had a bunch of other stuff going on. My mistake, Will be using it as a teaching/Learning opportunity.

Makes me question the quality of the valve seals...

Glad to give you all something to Laugh at! As far as the leaves this time of year come to north Florida there everywhere (no snow) windy and 72 degrees today.
I hope you haven't taken any of this personally,we spent weeks once arguing about what happens if you tie buttered toast to a cats back.Watch we are about to 3 pages of cats and buttered toast comments.

White is usually coolant entering the combustion chamber.Pull all the plugs and check for coolant. Use a pressure tester and check to make sure the system will hold pressure.Its possible coolant could be leaking from the intake and drawn into one of the ports.
