Oil in my air intake

[Silverback17]

I recently got a 2017 ram 1500 with 121k miles, I’ve had it less than two months and it’s left me stranded twice. I got the v6 for the “reliability” and I’m second guessing my choice. Started out with a misfire and then another one. Now we’re replacing the plugs and coils again and found oil in my air intake. I can’t find a reason why through google so I’m hoping somebody here knows why it’s happening and what I gotta do to fix it. Please help me out

Do you have pics of this? How much oil?

Could dat be blowing from the PVC setup where they dump it back in there???

@Wild one

Chime in?

It's coming from the PCV system which is recirculating oil laden air back to the intake for emissions re-burn.

Adding a catch-can will stop that oil from getting to the intake.

I should’ve taken a picture when I had everything out but it’s like a puddle sitting in the air intake when we took the resonator off. I’ll look into a catch can. Thank you!!!

Search YouTube to learn how to test and clean the PCV.

The following video is a bit long but very detailed.

Where is the PCV valve on a Chrysler 3.2 and 3.6 engine?

A catch can will take care of most of the blow-by oil, but the PCV can likely be cleaned or replaced while you wait for a new catch can to arrive.


The following video about catch cans is more about direct-injection engines, but it still covers the basics in great detail. For more Ram-specific related info on catch cans, try using the search utility in the upper-right corner. There are many threads on this topic.

If you are getting that much blo-by, you may have something else going on. Yoy might check compression/blead down to see if you have a ring problem on one or more cylinders.

• Failed PCV Valve/System: The most common cause, where excess crankcase pressure forces oil vapors into the intake.
• Worn Piston Rings/Engine Wear:
  High blow-by gases force oil mist up through the breather system.

Please narrow down exactly where this puddle is located. It sounds more like you're talking about the air filter box here when you mentioned a resonator. If that's the case a catch can won't do anything for you. A catch can can reduce the amount of crud that comes through the PCV system, which gets piped in near the throttle body. So anything from that point in can benefit from a catch can.

Just as an FYI, the intake includes everything from the filter box to the intake manifold. So simply saying you have oil in your intake isn't descriptive enough.

A Catch-Can is an unnecessary aftermarket idea. Millions (with an M) of vehicles operate Daily and for thousands of miles without a catch-can and don’t puddle oil in the intakes.
The problem and solution is much deeper than simply adding a gimmick catch-can.

This isn’t my photo but the oil puddle is here in the throttle body, when I took the air intake resonator off is when I discovered it. To answer your questions, and if you have any new advice for how to solve this

Your PCV valve is probably original and wouldn't waste my time testing it.

It is in the worst place possible on a Pentastar 3.6. The backside of the passenger side head.

If you go to the massive effort of taking it off just replace it with an OEM one.

Do NOT use an aftermarket one or you will be doing again.

Ask me how I know.

A little oil residue in the intake is normal.

The coils should be OK they last for a long time but what plugs did you use?

To do the plugs you need to remove the intake. What gaskets did you use and it was torqued back on properly?
