I had a fresh engine that lost oil pressure all of a sudden,one of rocker arms broke an adjuster screw and it threw the lifter out of its bore,not a good feeling when your engine is running and there is no oil pressure.
Your right. I don't like this at all, this 340 has been a pain in my *** since day 1. Today the passenger side valve cover is coming of for inspection, but so far everything else is good. It did have low oil pressure from the first fire, but it had about 20 psi during breaking.
