    Flywheel bolts gave me more crap, 5 came off no problem with an air impact, 1 nope, stripped the head a little, Wound up drilling the head off....


    First thing that jumped out at me when I popped the oil pan off was a destroyed bearing, looked around and it was for the "rear" balance shaft, the oil shaft.



    The front balance shaft was seized.

    Oil pump ate chunks but nowhere near as bad as I thought.




    Rod journals for the most part are okay, 1 or 2 spots I can feel a problem with my finger nail. the mains are much worse, I can feel the scratches with my finger nail but not the pad of my finger.
    I am hoping I only need a polish




    Flywheel bolts for this thing are not standard 6 bolt DSM, I had to order ones for a Toyota 3SGTE m12 with a UHL of 1"


    I have noticed what I've been calling the flex plate is actually the starter plate, and flywheel = flex plate. Shows just how much I know about automatics.

    So after a week of dealing with flaky people and shops that don't answer their phones I have accomplished nothing but receiving a big shipment of parts.

    OEM Mitsu:
    BS delete spacer
    oil filter
    brake rotors
    front case plug seal

    Aftermarket:
    Gates upper and lower radiator hoses and thermostat
    ARP flywheel bolts 203-2801
    exhaust gasket
    magnetic drain plug
    fuel filter and crush washers

    Also I'm playing with trying to bring the group 51 starting battery and a group 27 marine battery(from a TT) back to life. I am trying to do it without draining the acid but I did pick up a bag of epsom salt at the dollar shore just as a last resort.

    4G6x guys, check out the front case plug, not a "castle nut" like is typically found on 4G63 and 4G64s.

    I would assume it's original to the van's G64B since all the other parts were OEM inside.
