  • While water in the oil is always a problem, oil in an N radiator is not usually a problem.

    Some anti-freeze has water pump lubricant in it. Or someone might have put stop leak in there. That's oil. Because it's a flathead, no oil lines are above the head gasket. But, you could have a leak in the head gasket which will produce a sheen on the coolant thanks to combustion gases. Or, if you have a leaky head gasket & the engine is burning oil, you will get more than just a sheen of oil in the radiator.

    Any performance problems?

    While a compression check can tell you that you have a gasket problem, itís not a sure thing. A leak-down test will tell you if itís leaking for sure.

    Meanwhile, re-torque the head to specs: 50-55 ft lbs for nuts, 65-70 ft lbs for bolts. Torque it in the proper sequence.

  • Bruce gives you good advice.
    I would guess head gasket leak, or someone may have dumped some oil in there long ago.
    When was the last time you changed the coolant?
    Or when was the last time you did not see oil in there?
    Torque head is a good idea.
