Hi, Looking for any thoughts on the engine issues with my 861 gas tractor. It smokes quite a bit with blow-by coming out the valve cover vent and the oil filler tube. I ran the engine to operating temp for a while with both valve cover vent filter and the oil filler cap removed. Smoke coming out of both. After running a while, I noticed the oil in the inner sides of the oil filler tube collected some oil that was tan colored.... as if it were water contaminated. I changed the oil and the old oil looked okay, it was not discolored and did not appear to contain water. The compression (cold engine; dry) ranged from 110 to 125. I tried looking for oil in the radiator, but did not notice any. I would have to do that again to be sure.
Does this sound like a blown head gasket or worse? Local mechanic thinks its a good engine and just needs a valve job, but they did not spend much time looking at it. I can get a good used engine for 20% less than the valve job cost, and worried my engine will have more issues that will escalate the cost.
Thanks.
