    I JUST REPLACED MY HEAD GASKET ON MY 6.2 DIESEL AND AFTER I HAD FINISHED I CHECKED THE OIL AND NOTICED IT WAS LOW SO I GO TO ADD OIL AND I SEE GREEN ANTI-FREEZE IN THE FILLER NECK.

    DO I HAVE TO REBUILD THE WHOLE ENGINE NOW OR SHOULD I JUST CHANGE THE OIL / COOLANT AND JUST RUN TILL IT DIES?

    IS THERE ANYTHING ELSE I CAN DO FOR IT?

    Take the capslock off. Have you run the motor after you replaced the gasket? If you haven't, I would think that is from when your gasket needed to be replaced. If that were the case, I would drain everything out, add oil and let it run for a little while, drain that out (I know it's expensive on diesels) until you don't have any coolant in the oil. If after a couple of times it doesn't get better, then your new gasket is leaking.

    If the coolant is there after you have run the motor, then the gasket is leaking. Did you have the heads machined?

    Turn the caps off....What was the reason for changing the head gasket? Should be able to dump the oil and filter and run it for a while and then do another oil change. If you don't have a cracked head or block a little won't hurt. If it continueas to have coolant in the oil, then you have a problem.

    Sorry about the CAPS, anyway I haven't run it yet so I am assuming that it was there before I put the new gasket on.

    We had this problem in our auto shop's late 70's Gm pickup. It turned out to be a cracked head, but hopefully this isn't your case.
