Thanks Oly,

I have the same thoughts, other than this the engine runs great. I have a 12 volt battery and alt in the truck and she starts every time in 2 turns or less. The idle is very smooth and temps and pressure are right where they should be. I am thinking someone tightened that valve too much, or at least I hope it is that simple

Thanks again, grin
