This engine has only 175 hours, bought 1 year ago from my uncle. Had mechanic rebuild 4 carbs and replaced water pump impeller. I changed Engine oil, looked fine, no water.
I've used motor about 5 times,10 hours.
Hadn't used motor in 2 months so I checked oil prior to running in driveway and it is white/cream color.
Drained oil, changed filter and ran with hose water to put new oil through motor. New oil also has water but I kinda expected it, not sure if its new water or existing water/oil. Engine starts easily, idles a little rough.
Removed spark plugs, #1 has brown colored buildup, #2 slight black, #3&4 very little buildup/discoloration. I have pics of plugs. Trying to get compression tester to perform test. Ordered Yahama service manual.
Asked around and was told don't waste time/money and some say head gasket failure.
I know this motor is 16 yrs. old but it has very low hours and looks showroom clean.
Can water contaminate oil if water pump replacement damaged something?
THANKS for any guidance.
