I went to change oil on my new 468 for the first time I have one good weekend on it. I went to pull the disributor and it was "milky" at the collar. Pulled the valve covers and found water and the the front rockers on both sides were pretty gummy. I could see down on the cam and could see milky oil in there also. I pumped the oil pan out but found little evidence of water down below. Oil was a little hazy but not milky or frothy. I run injected headers and also evacs to the valve covers. Anybody have any problem with water or steam getting back in the engine through the evacs? I'm not getting any reversion with the injection system (i don't think). They run nice and dry below 2000 RPM.
