Stop in for a cup of coffee

Got the hi-rise intake off and the streetmaster installed. It leaked. Coolant port on left front has a significant gouge in it. I loosened and retightened it,owner insisted we dump in rad sealer. Seems to have worked. My concern is collant in the oil.
All said and done, he leaves intake, air cleaner, and a pair of chrome valve covers on my bench.
And sold him my dealership ramp. Difficult day. Im hurtin. Bad.
