Catch can oil under hood

[Olikestrains]

Hey so I’m new to the world of catch cans. Today I just completed a 600 mile mountain drive with a lot of time spent at high boost and when I completed it and went to plug in the block heater for overnight the underside of the hood and all components around the catch can were coated in a film of oil. I’m using the Buschur pro vented catch can and have 8000 miles on this truck. Just wondering is there a way to prevent this or maybe a modification so it vents outside the hood.
thank you.

Don't use a vented catch can. Problem solved.

I'm not convinced that these do anything in real testing - i.e. long term can vs no can. Not "hey look what crap my catch can caught" - just "catching" stuff isn't necessarily solving a problem.
Its a mod that aftermarket loves to sell though.

Sounds like the can was full, you periodically drain it, correct?

Ignorant here. What is the purpose of the catch can? I know they use them on high horsepower professional drag racing cars but this is a four-cylinder engine. If this was an issue wouldn't ford have provided one from the factory?

Yes I do empty it every oil change so every 3500 miles. Ill keep doing it more often now and see how that affects things.

So the main reason I added one is to prevent carbon build up on the valves and keep oil out of the intercooler. Not totally necessary but should help longevity

I’m also thinking the oil mist was due to the vented can - I’m not sure in theory why they make a vented can when most systems are sealed - anyways I started by adding a universal kit oil
Catch can on the clean side of the PCV side (rear of the engine valve to intake tube) it’s the east side to install - I remove it every 4k miles when I change the oil and it holds about the lower 1/4 of a 4 ounce catch can - I find oil water moisture stuff that has a orangy hue - that stuff would normally hit the intake valves - I recently added the UPR Maverick specific catch can - it goes on the front side of the engine from the lower intake manifold to the block - it’s a tougher install because you have to reach down deep under the intake, manifold blindly disconnecting, two PCV hoses to install the kit - i’ll be changing the oil probably in about three more weeks since I did the install into an oil change cycle - I anticipate it’s going to do even a better job because ,
at 9000 miles on my Maverick I found oil in that little U-shaped PCV line I removed under the intake manifold- I work in the service industry around GDI gas motors every day and see the heavy deposits left on intake valves causing driveability problems at higher miles - the cans are cheap maintenance to prevent heavy repairs bills later involving cylinder head removal to service gunked up valves - hope this helps - heres my install - BTW I also decided to do this because I am running a panda module that increases the turbo boost a little bit therefore increasing crank case pressures, so I want to play it safe. Here’s a couple of pictures of my install. hope this helps others.

With a carburetor the gas would wash the oil off the valves. Now with direct injection the oil from the crankcase could stay on the valves and carbon them up. So, the oil from the crankcase goes into the can instead of the intake.
And yes, or maybe.

Yup that’s pretty much correct - with the carb sitting on top of the intake manifold air and wet fuel mist was always hitting the intake valves keeping them clean and sealing the cylinder like they are supposed to - when multi port injection came along each intake runner had an injector - same thing keeping that valve clean - with direct injection the fuel injector fires directly into the cylinder bypassing the intake valve - the normal crankcase vapors that carry oil mist are introduced into the intake manifold through the PCV system for emissions, but that oil mist ends up on your intake valves and turns into carbon overtime not allowing the valve to seal properly creating different drivability problems- oil catch cans act like a oil mist filter so to say -the heavy oil particulates collect at the bottom of the can with minimal oil vapors, making it to the intake, manifold, and your intake valves - company’s like BG offer a strong intake valve cleaner that is ingested through the intake with special equipment while the engine is running to try and keep those GDI motor valves clean / I can only assume research goes into that so it probably helps and then in conjunction with a catch can set up I expect a lot of trouble free miles out my my ecoboost 2.0 - you can’t hurt anything by installing an oil catch can if installed correctly ….

Ford would not provide one from the factory. Instead, Ford provides Multi-port Fuel Injection (MFI) standard on the the V6 and V8 engines. Maverick EB2.0 has only DFI, somewhat justified by the relatively low price of this truck. I don't believe that the Maverick EB2.0 need one, much less two of them. Then again, I don't plan on having the Maverick for long...

They do provide one from the factory. Check the bolt-on panel where the PCV line exits the side, and you will be looking at a factory oil separator. That's why all these guys installing extra catch cans are not getting anything in them except a small amount of water.

@RedRider... Do you have a picture of that? Thx...

I think I'd prefer the port injection. The small benefits with direct injection might be outweighed by the drawbacks-- very high pressure fuel system, dirty injectors, difficulty of changing injectors, etc.
