equeen said: (quoted from post at 11:53:40 09/25/12) Years ago had oil in radiator of an 8N. Took tractor to mechanic who repaired - said cause was a blown head gasket.
Have a '50 8N with oil in radiator and low compression on cyls 2 & 3. Decided to tinker myself.
Photo (I hope) shows gasket still on head. Bits left on block. I don't see anything "blown".
What am I missing?
If gasket wasn't "blown", then what are other possibilities for oil in water?
Thanks.
This is only spot that I see that might look suspicious. Need to look at other side of gasket, too. Don't see any evidence of steam cleaning in combustion chamber, which suggest to me that you have no water to cylinder leak.....were you needing to add coolant often? No? Then probably no leak. I will never understand why people just "have to" jerk an engine apart BEFORE diagnostics! Just waste of time/money & destroys evidence that might help diagnose the problem, if one exists. There is no direct path for oil to be pushed into the water jacket in this engine.......no oil passages in head or head to block interface/gasket. IF, if you had a compromised head gasket connecting cylinder to water jacket, then at best some combustion products could find their way into the radiator, but that would NOT be a lot of oil & if observant, one would see the bubbles in the radiator. IF you had a cracked block between water jacket & crankcase, that would yield water in oil pan, not oil in radiator. What you probably HAD, was a perfectly well operating engine, with an oil-sheen in radiator resulting from lubricants in coolant.......probably only thousandths of an inch thick, on top of water/anti-freeze mix.....nothing to be concerned about. If you are good & lucky, I will be as good as it WAS before when you put it all back together.

Today's Featured Article - Product Review: Electronic Ignition - by Staff. Oil, for example has come a long way in the last 50 years and I don't use anything but the latest API grade available. I've heard the arguments for non-detergent oils but would never trade it for today's formulations. Paint is another, the modern acrylic enamels are great for resistance to grease and fuel stains, retaining their shine and they last forever; unlike enamels and lacquers . Still another is the alternator. No doubt using the original generator keeps the tractor pure, but for thos
