Oil, Water, and Steam Oh My!
OK this may turn into a long post but want you to know all the details. Once again, son's '98 bought last year with 6000 miles on it, now at about 15,000. Thought low mileage was good but didn't think about dry hard seals etc.
Have had over heating issues before. Blew a hose, had a bad fan and replaced thermostat. After that, blew head gaskets, had water in the cylinders. Replaced those and it ran for a month or so and bent a valve, replaced rear head. Since then been running fine. A week or so back he had hot water and steam come out of overflow bottle. Refilled radiator seemed ok. Yesterday went to Daytona, I saw steam coming out from overflow bottle but he said temp was normal. When we got home I saw steam coming out of oil breather filter and after a while condensation on the filter. We check oil and added water but seemed ok. About 10 min later he called me to say that oil was blowing out the breather filter (it was after dark). Had him come back and I saw it was oil and water. Site glass was fogged up, when I drained oil it was a dark gray with a little whitish marbling thru it, but not brown.
No oil in the water that I can see.
1. If impeller seal was bad will water get in oil or oil get into the water?
2. Compression is good, don't have a leak down gauge but hook air up to cylinder and could not hear or see escaping air.
3. Engine runs fine, starts right up and has power.
4. Once it's warm I get it to throw water out of filler cap when I rev engine and spin the water pump.
Maybe when it got low on water it built up steam that pushed itself thru somewhere and out the breather.
Any Ideas? Hopefully something simple I missed.
