    Question MK4 1.7 Diesel Isuzu Oil Cooler Bypass

    What exactly do I need to do to bypass the oil cooler? I've got oil in my coolant header tank.

    Hey John,

    Nobody replied to this at all? I guess you saw the recent posts about leaky oil coolers and possibly bypass. What did you do about yours in the end?

    Cheers, Paul

    No I didn't see the recent posts. Because I have bigger problems with the car right now I'm not as worried about this. I just had a new head gasket fitted so I'll see if that sorts it, if not I guess it has to be the cooler.

    yeah, sorry to hear about the head gasket - fingers crossed the one on the diesel doesn't blow. I had one go once on a 1.6L Astra and it was rather expensive to get fixed down here...
