no the timing cover is spray bomb so is the block and heads. i had just put that motor in at the time. the spray can was fresh. the intake, valve covers and water pump are urathane and 3 years old...
where is it falling off? everywhere it was spray bombed. yes i cleaned the hell out of it. no i didn't prime it. it was only going to be in there a year or i would have painted it with urathane..
if you want it to hold up and last. look 5 years down the road like the day you sprayed it go get the epoxy primer and the urathane paint and spray it.. not much else to say about it really.
