Water oil separator

I keep getting water up the breather tube for my valve cover and into my oil, y'all think a in line oil water separator for a air compressor would help?

Probably not. Water separators are basically designed for pumped flow like removing water from a diesel fuel line.

I would be more concerned about where this water is coming from. If you live in a very damp area you might see a little water in the tube from condensation.. however you state you see in in your oil?

I doubt a water separator from an air compressor would work. Different pressures and air flows.

The stock breather takes air from the intake tube after the air filter. Is your air filter getting wet or do you have the breather tube rerouted. You could always move it somewhere dry. It's just a source of fresh air for the CCV system.

Moving it is easy. Just buy a few feet of 1/2" PCV hose from your local parts store, a 1/2" barbed union, and a cheap universal breather filter. Then you can put it wherever you want. IMS there is enough of a gap near the hinges to let you stick the breather in the cowl but I'm not 100% on that.

You can use 1/2" heater hose temporarily but eventually the hot oil vapor from the engine will make it soft and it'll fail.

Look into the Ford Windstar cowl intake swap. It’s a paper cone filter that moves a lot of air. Lots of TJ guys go that route.

I’m sure you could also reroute the pcv at the same time.

Since the stock (I assume yours) breather takes it from the air cleaner, perhaps you should consider a snorkel or other modification. You want to be careful what goes through the throttle as well

I've been trying to avoid going to a snorkel, though with all the rain we've been getting I may not have a choice theres parts of the pit that are close to 5ft deep though by that deep everything else would be full of water as well ask me how I know

At that depth I think you need to be more concerned about the electrical system.

Follow the build!

Grease every single electrical connector you have in your Jeep, protect electrical components the best you can, block the transmission breather located in the fluid pump and relocate it to top of transmission housing with an a tube all the way to cabin roof.


Hope for the best, and be prepared for plenty of issues in the near future. These things aren't built for deep mud..
