where's the lt1 engine guys?
motor spun one rod bearing. Bought remanufactured crank, New main and rod bearings, had the rod reconditioned, New oil pump, and installed motor and has very little oil pressure. Could get none cranking it to prime it so I started it and it jumped to 20 at idle and then faded away to nothing. Zero! Put different oil pressure sender in and same thing. Put mechanical gauge.....same thing. Took the motor back out inspected cam gear....looks good. Drive gear on shaft.....looks good. Oil pump moves oil when I spin it by hand. No broken plastic sleeve. The only thing I have not looked at its cam bearings. Could it be that? 93k and wiped out can bearings to the point of no oil pressure. I'm stumped. Ain't my first rodeo with doing this but first time with lt1. What am I over looking?

Spun cam bearings usually starve the top end with out much effect on the gauge. Either the pump is crap or its sucking air...or there is trash in the gally to the sender. Pull a valve cover to see if oil is making it up top.

Been rebuilding engines for over 20 years and have never seen such a thing. Guess the only thing left its cam bearings.I just can't imagine it being that. Send like oil is flowing good just don't build pressure.

I experienced this scenario once a long time ago. did you by chance replace the cam galley plugs without grinding the factory burr from being staked in. I did that once and had the same scenario you have. pulled the motor, tapped and installed pipe plugs and all was well.

That is correct. When I bought the car, with the rod bearing spun, the car held oil pressure. Not that I ran it that long but it did not drop to zero. Yeah I know....crazy ****. I don't know what I was thinking trying to take a short cut, personally I have never seen a cam bearing do this. I'll be looking from now on, that's for sure.
