    Default 4JB1T - Overheating / repair / diagnosis?

    Hi guys,

    Need some help here please. FIL seems to have cooked the engine of his Isuzu. What I have so far is that he had a leaking waterpump and somewhere over the past weekend, he had managed to overheat the engine. He checked the water in the radiator prior to leaving the house, but didn't check the expansion bottle. Drove the bakkie hard as he was running a bit late and on way home it seems something has popped. Pulled off and had the bakkie towed home and hasn't started it since.

    Any ideas on where we can start looking to assess possible damage? He is a pensioner, so replacement engine should be the very last option (prior to complete rebuild) oh and because of said pensioner status, him and I will DIY the repair as much as possible (will check in on the forum for advice on the DIY part as well )

    T.I.A.

    I’ll check tomorrow afternoon if it swings. He can’t seem to remember if he tried starting it again or not.

    If it starts and the engine runs, I suppose I can assume he got lucky and that damage might be limited to the head and head gasket?

    Sorry to hear about the troubles.

    Been there done that.
    A compression test on all 4 cylinders is a good place to start.
    I'd do that before trying to start it.
    If you do start it, check for excessive breathing/smoking at the oil filler cap.

    Hoping for the best.

    Thanks guys. Busy having the battery charged up and then have a look Saturday morning. If the engine is shot, he’ll probably sell it as is.

    UPDATE:

    F.I.L. decided to tow it to the mechanic. Opened up the engine and somehow the one piston sleeve dropped out of the block / in to the block.

    He's sold it as is.

    More a case of finances in this instance. When you’re a pensioner, 25k can be a lot of money

    Want to cry some more?

    The cause was a leaking water pump which I offered to replace numerous times
