Water in oil?

[Gary H NC]

I was taking the boat out today and was doing my usual checks.The oil was about a half quart low.<br />It looked fine on the dipstick but when i removed the fill cap i noticed the inside of the cap was milky brown.<br />Is it normal for these 4.3 motors to have enough condensation in them to cause this?<br />I recently had new head gaskets put on and complete tune up and oil change.The engine seems to run great.Temp stays around 150.<br />I also noticed some condesation coming out of the hoses from the valve covers that go to the spark arrestor....it just got me wondering..

How hard did you run it?<br /><br />150* is low. Should be around 165*.

I just had the same problem, but after posting pics on i-boats have been assured that it will cook out.

I run it pretty hard yesterday,At wot the temp gets to about 160.I checked this morning and the milky stuff was back on the inside of the fill cap..<br />i just put in a new 160 thermostat.<br />Oil still looks normal on the stick.

I have been down this road also. Change the oil, water won't show up on the stick, it goes to the bottom of the pan. Does the oil seem to be reproducing on its own? Figure this out quick it could ruin the motor.

I think i'll change it before running it anymore.<br />No reproducing..thats a good sign..actually it was a half quart low.<br />Thanks Dave!
