Contaminated Engine Oil - Milky shade to Crankcase oil

[andyfresno]

Mike,

The milky oil is caused by water in the oil, which obviously you already know.

I had this problem once when I didn't go back and re- torque the head nuts.

Did you take a really good look at the top of the block? Put a straight edge on it?

The next things to consider aren't good - -cracked block, etc.

I always put a can of stop leak in the radiator when I have the head off - -some guys think this can clog things up - -but I haven't had a problem. - -I'd try that before you consider what's next.

Oh - -by the way - -if the stop leak fixes the problem, your oil will still be milky from the small amount of old oil left the engine, but it shouldn't be as bad
