Engine overheated in sub zero weather. Think the radiatior froze. Now there's fuel in the oil. Where do I start to find the leaking fuel?

don't think that a solenoid stuck, but could have. Surely a warped head wouldn't have leaked that much fuel into oil? No, have not removed head yet. Removed radiator and looling at fuel injectors and heads. No water in oil.

If you ran the vehicle for a long time with a warped head and it wasn't firing, the raw fuel could have made its way into the oil. Also, in cold weather, if you are making short trips, it never warms up which can cause it.

I would recommend making sure the injectors are not leaking. Pressurize the system and see if it loses pressure quickly.

Let me know what you find.
