I never heard of that. I change my own oil every time. So you are saying I need to pour it in more slowly? Confused.

 

Rob, you might want to have a look at your throttle body. If you decide it needs cleaning, be careful to use a compatible cleaner, folks have ruined the sensor using carb cleaner, etc.

 

I have a 2017 JKU Rubicon I purchased new and currently have 45,000 miles on it. I've had oil on the air filter problem for a while. I had every service preformed by a Jeep/Chrysler Dealership. I've ask about this a couple times and was told this isn't unusual. Funny how I've never had a Dealership say I needed to replace my air filter. I do replace it myself regularly. A week or so ago I had a check engine light on P0016 [code is something like camshaft out of sync]. I have an intermittent miss at idle, seems to be running fine. Not using any oil. I'm still under the 6 year 60,000 mile warranty plus I have an extended Chrysler Warranty in effect. The dealership says the engine code is because my air intake, between air filter and engine, is dirty. Actually it is oily and dirty, because of this my engine is shot. I would imagine oil residue in the air intake might have something to do with the dirty intake. I didn't see oil in the air box so I didn't think to check the intake. But I'm not a mechanic and I've been paying for the dealership to maintain my vehicle. Dealer says my compression is 60 to 65 psi. I'm not a mechanic so I may not understand, but if the camshaft is out of sync can you get a proper compression test? The Dealer and Chrysler say I need a new engine. Chrysler and dealership say this my fault. Remember every service has been preform by a Chrysler/Jeep dealer they have never suggested I need a new air filter. The inspection sheet they provide after a oil change shows worse case for air filter is yellow. I think red means should replace, purple is must replace. I actually have receipts from Amazon for 7 air filters I've replaced. I've done more filter changes on the road. Unfortunately I never realize I needed to inspect and clean the air intake. It is a Jeep and I have driven on dirt roads. When I'm in a dust dirty area I do change the filter more often. Seems to me if I was supposed clean the air intake it should be mentioned somewhere. According to the Magnuson Moss Warranty Act Chrysler must prove I caused the failure. I have finally been able to talk to Jeep Cares. No discussion just a young lady who repeatedly told me Chrysler won't honor their warranty. Chrysler's idea of proving it was my fault is because they say so. My Mom use to say that too. Oh the Jeep Dealership actually offered a good deal on a Mopar remanufactured engine, it comes with a WARRANTY! Guess what I told them? Hope the Bronco is a good vehicle I've had it with Fiat/Chrysler.

 

This is kinda silly, a small amount of blow back pushing oil through the pcv and into the intake isn’t going to cause any issues. Filling oil too fast isn’t going to do anything either since the oil fil port goes straight to the sump.

 

I once had oil in my filter on my 2012. I took it to the dealer. They said I filled it too high.

 

That makes sense. Too high oil pressure, the pcv is doing its job by releasing excess pressure.

Your cylinders eating oil, burning it up and spitting it out of the exhaust beats the heck out of blowing seals (or worse) in the bottom end of the engine.

 

I just used to dump 6qts in without checking. I guess it was just a little too full. In this rare case, I think the dealer was correct. It cost me $120 for them to tell me that.

 

Thats not too bad, I can beat the $120 by a long shot.

In my early days of bending wrenches, I rebuilt a 22RE engine from an 80’s 4-runner. I was super anal about all the work I did and followed the book, talked to reputable performance shops, etc. I built a beautiful engine and was proud of the first engine I built.

I also found oil in my filter and I take. I wasn’t very smart on engines yet at the time and I let someone convince me that my piston rings weren’t seated properly and that was causing my
blow by. So, I ripped the engine apart again and had the cylinders honed... again. I replaced the piston rings and put it back together.

Still... oil on the filter and intake. It wasn’t much. Later I learned that it’s normal on some engines and if your exhaust isn’t blowing any white smoke then I have nothing to worry about.

That lesson cost me about $500 and a lot of time.

 

This may be true if the PCV valve was on the same side as the oil fill was; the PCV valve is on the passenger side valve cover.

 

Check to make sure the silencer on your hood isn't falling into your air box choking it's only air source and causing it to suck out the valve cover
