I figured it out on myself that the loss of oil pressure was due to a secondary timing chain tensioner that came lose. So I tightend it down and oil pressure is back. I runs fine now except for knocking for one second at startup. This only happens if set over night. After the engine is just shut off it start back up normal with no noise.
I suspect the primary chain tensioner o ring is bad causing the oil pocket to slowly drain back down.
Do you think that is it, if not then what? Jared
