I received enough good advice on troubleshooting my oil pressure problem searching old threads, I figure I may as well join. Regarding the oil pressure, it suddenly went to "0" on a 40k RB that has always maintained excellent OP. No Oil from the pressure sensor port. No knocking, but valve noise. longer story abridged, Pulled the right side valve cover and then see #4 pushrods (both) bent to hell, one with a near 20deg angle on one end. Both lifters out of the bores and laying in the valley. tried to pull them out with a magnet but no luck, so I guess I'm pulling the intake next weekend. Here's the remaining question(s).
-- Assuming i lost oil pressure when the lifters left the bores and no longer maintained pressurized oil routing through the Rt gallery to the crossover correct?
-- I'm guessing a stuck/sticky lifter(s) bent the pushrods, valve springs look good, haven't been able to get a compressor on the valves to test they open, but they look ok, rockers look fine. Should i be suspicious of that diagnosis and continue looking? engine was idling when I think I heard pushrods bend (hindsight), drove 1/2m home with good oil pressure but a miss. changed plugs in hopes of fixing the miss and after startup, noticed valve noise and then saw the pressure gauge, shut right down
-- I'm thinking about just ordering a new set of lifters and pushrods and pressing on unless I find anything else, but I'd like to be more confident, any place I should look at specifically? I'd rather not pull the heads, but if necessary...
Thanks in advance
