Please Help, Stumped Everybody

O.K. I still have oil spraying from the breather to the airbox. It is a chocolate milk color but the oil in the motor is not.(dipstick and oil pan have regular colored oil.) I did a compression test-rings are fine. I replaced the pcv valve, still happening. I've tried everything. Is there anything I can put in it to try and stop this?(i.e. engine restore, seafoam, lucasoil) This has been going on forever and nobody can figure it out.

Your rings are probably bad, and your shooting oil and its mixing with the gasoline. Only real fix is to tear her apart.... Most of those cleaning additives IMO would make it worse. Try a thicker oil. How much oil are you consuming if you are? A half a quart a week?

I tried switching to 20w-50 and it didn't do any good. I don't think the rings are bad, the compression was around 140 on all cyllinders. I'm using up about a quart a month

A cylinder leak down test would find any cylinders that have excess leakage into the crankcase.
The coloration is a combination of oil, moisture combustion blowby and possibly gas that condenses on the colder Pcv and intake areas.
If the engine is using oil by the rings into the combustion then the resulting combustion gases can get back by the rings.
Worn valve guides, coolant leaks can contribute to all this.
Often short drive times make this worse

Sounds like your motor needs to be rebuilt.
