    I already shook the rods by hand, no noticeable play. I took the valve cover off also and nothing appeared out of the ordinary.

    I am a huge proponent of rebuilding the spring section of the oil pump anytime the motors apart. Just the spring and cup is all that's needed if the pump passes the factory inspection protocol.

    Re: Low Oil Pressure at Hot Idle

    So, looking back at my build thread from when I was going through this engine after I bought it. I DID replace 1 rod bearing because it had some scratches in it, although the crank journal was fine. Anyway, guess which rod bearing failed? Yup, the one I had replaced. #3. Not sure why, all proper procedures were followed. Maybe this engine was just toast from the get go. Who knows. Not sure on what I am going to do at this point.....

    Oddly enough, I held on to the original bearing/the one I replaced. It was still in my tool box:

    I've got the original engine for this car sitting on an engine stand right now, I can just re-build that and swap it in. Or, there is a local guy selling a "25 year" collection of Turbo Dodge parts. I may call him up and see if he as a T2 or 2.5T common block in his stash and just start with that.

    A bit late to the party but for a new motor, sure looks dirty in there. I'd hazzard a guess the motor wasn't cleaned properly when rebuilt. The bearing you took out isn't bad, just show's debris damage.

    Yeah, I'm tearing down my spare engine now and putting a plan together, it's an 86 T1 engine. I am currently debating whether to keep the "light weight" rods or upgrade...

    How fast do you plan to go? If you're keeping the log i don't see any real reason to upgrade.

    I'm going to go T2 conversion this time around. Reliable weekend driver, may never see a drag strip. 200 hp would make me happy. I've just ready horror stories of light weight rods failing on even stock engines.

    Re: Low Oil Pressure at Hot Idle

    Well, to my knowledge they fail from detonation and over-rev (misshifts). I just ran 96mph in my caravan on LW rods which calculates to ~230hp. I rev to 6200. These rods have ~240k non-turbo miles on them before i turbo'd it (tbi bottom end).
