It's been a while since I mentioned the moisture/foam on the engine dip stick. Don't have a clue why, but it went away after I cleaned the dip stick and the tube it slides in. Maybe high humidity was the cause ??

 

Its probably condensation some engines get it when they are drove only short trips.

 

As long as it isn't foamy milkshake you find on your dipstick, or coolant, don't worry about it
