    Looks good! I just hope you've gotten all of the metal shavings out of the engine. It takes a very small amount of them to get ground up and start causing damage to bearings/surfaces, pistons/walls, etc. Unfortunately, I have a Nissan engine that suffered this fate...

    We left a single metal shaving inside because we're using the homeopathic approach to engine health.

    Just kidding. But seriously, sorry about your Nissan.

    I laughed a surprising amount at this. Thank you

    Congrats on the progress!

    Okay, it did sound pretty distasteful.

    (This is a car forum, so I hope I don't have to explain that one.)

    a/c compressor

    The oil filler got in the way of the a/c lines, so spacers have been installed - and, as a result, a slightly longer serpentine belt has also been installed.

    Bill informs me that the engine runs fine, but has a slight vibration and pulls less vacuum than expected.

    As far as I can remember, #2613's engine always made a vibration. At idle speeds I could feel it in my seat and the steering wheel. I kept asking people about it, and they kept telling me "It's an odd-fire engine, so it does that." I eventually just gave up looking for the reason and accepted it as a fact of DeLorean ownership. But perhaps a previous owner swapped in some "performance" camshafts and I didn't know about them.

    Anyway, Bill was able to get the engine to pull 13 inches of vacuum at idle by advancing base timing up to 18 degrees. We won't know until a test drive is made if there may be any problems with detonation due to the timing advance.

    Yikes, that is a lot of timing. My 3.0 pulled 19 at idle at 10deg btcd

    Is the compression good on the motor? perhaps an issue with the timing?

    Compression test results:

    Cylinder 1: 150+ PSI (needle just to right of hashmark)
    Cylinder 2: 150+ PSI (needle just to right of hashmark)
    Cylinder 3: 155 PSI
    Cylinder 4: 160 PSI
    Cylinder 5: 160 PSI
    Cylinder 6: 160- PSI (needle just to left of hashmark)
