I havn't figured out why the loss of oil pressure yet, but here's the history:
1/ oil light came on
2/ driver continued on for a few miles until engine seized when he idled down
3/ pics show 2nd rod bearing babbit seized to crank (I can polish it !!!...maybe....). Bearings had spun...tangs gone
4/ oil pan was full of oil
5/ oil pump tested by hand and pumps fine
6/ oil pump driveshaft intact
7/ installed oil pump drive shaft from underneath. Would not turn, so cam sensor seems OK. Turned engine by hand, and oil pump driveshaft turned properly
8/ oil filter was last part removed....comletely empty...no oil.....not a drop....very weird.
I'm wondering if there are any press-in plugs in the oil galleries between the oil pump and the filter, but I still suspect the cam position sensor as my only test on it so far was pretty Mickey Mouse.
Any ideas what caused the loss of oil pressure?
