Was this the professional edition or the Harry Homeowner version?

If you assemble without measuring and ciphering, you are taking a big gamble.

Edge,
You are correct, the oil pump on the late model 3.8L is a georotor style, driven directly off of the crankshaft. Therefore, it is not possible to prime the pump in the normal fashion, with an electric drill motor.

I am still concerned about the shape of the main bearing housings in the case, if there was a spun bearing. Once the bearing begins to spin it erodes material in the housing and the bearing shells will not crush properly (if at all). Even if the crank is reground and new bearings are installed, the case itself can be bad, wherein it would need to be align bored.

Regardless of whether you are installing all new components or reground crank, etc., all of the bearings should be checked - at least with plastigauge.

Your rebuilt engine should carry at least 40# oil pressure at idle. My 2001 3.8L holds a steady 50# at all times. Good luck.

What I meant was did he pack the gears with petroleum jelly so that it would insure initial oil pickup?

On this type, one could pull the plugs (disable spark and fuel delivery) and spin the engine until primed. It would at least insure initial oil flow, right?

Well I dont have any pressure. The gauge I found didnt fit so I just cranked it w/o the sending unit on and nothing came out. So I guess I am breaking back into the front cover. Better do it before It decides to snow on me I guess...Thanks for all the help guys...
