Albert is correct, we won't know until we take the pan off and see whats going on.. i'm going on based on the jz started life as front sump and jordan bought only the rear sump pans and had the machine shop install it. unless they bought a new one and installed or modified the original pick up line in there to work witht he new set up, i believe this is where our problem lies. I almost want to have the Machine shop take it apart and install so we don't void an "warranty" their labor may have.
as much as we cranked it to try to prime the system and not getting a single drop out of the turbo feed line or at the oil filter, it's either not lubed up or no pick up line. currently these are (plausible) speculations until confirmed
