  • My 48 8N had water in the oil when I got it and I suspected the head gasket which is just what it turned out to be.

  • Like stated, a little is normal but if you have coolant in the engine oil, that's a serious problem. Could indicate a cracked head or cracked block.

  • 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.
