Milky Oil

[X5 Owner]

I've got some milky oil but engine runs strong and doesn't overheat. Any suggestions?

Don't run the motor anymore with milky oil.

Find the water leak, change out the oil a few times within a few hours.

Where should I look for the water leak? I took it to a mechanic and he said there wasn't a cracked head. I'm thinking worse case is a head gasket.

How would he know if the heads aren't cracked, without disassembling it? That's impossible.

Sounds like a cracked head to me.....

Warped head or bad gasket. I don't think off season condinsation would be enough to have the oil get milky but that would be best case.

Where are you located? Did you winterize?

I'm located I'n Houston. I actually just purchased the boat and found this out later. It's a 2000 X5 and has been sitting up for 2 years. I don't know much about marine engines but this thing runs great and has oil pressure and doesn't get hot.

Did it get below freezing during those 2 years?

And welcome to TT. Lots of really smart, friendly people here who love to help out.

Thanks. Glad to be a MC owner.

Yea more than likely but no really hard freezes. The lowest is usually around 29-30F.
