Oil getting on air filter

In Dec. 2014, I discovered the air filter in my 2012 GC with 34,000 miles was soaked in oil. The technician at the dealership determined that the PCV valve was partially clogged and when warm, the PVC hose would collapse. These two parts were replaced and I installed a new air filter. Fast forward 6 months and 4,700 miles later and the same thing happens. The same technician checks things out and the PVC valve and hose are good. He said he could not find anything in their reference material about what could be causing this to happen. He said the next step is to order a new intake manifold which will be covered by the powertrain warranty. Anybody have any thoughts on whether replacing the intake manifold will correct the problem? And I say they should replace the air filter. Is it worth the effort to try?

5.7 hemi. They just replaced the intake and see if it corrects the problem. Oh yeah, they are replacing the air filter at no charge. 👍

Re: Oil getting on air filter

If you pour the oil in took quick during an oil change, it can back up and go through the hose that's connected to the airbox.

Too many mods to list for each, so let's just say a lot was done over the years.

The oil was changed on 4-21-15. Would this happen immediately or could it take over a month? I checked the air filter 2 weeks after the oil change and the air filter was good to go, no oil on it.

It's something that happens right away. In your case then, something is causing pressure to build up in the crankcase.

Re: Oil getting on air filter

Well, the intake manifold and the air filter have been replaced. Now there is a strong smell of gas in the garage. It seems to be diminishing as time goes by. We'll see how it goes from here. Thanks for all of your comments.

Hmmm, I'd be concerned about a strong fuel smell after a manifold replacement.

Are they saying you have a lot of blowby or similar, such that a catch tank would be a waste of money?

They never said and I never asked. The smell of gas is gone. Maybe it was spilled gas in the engine area.

Bingo!! That's been my experience with my 2012 Summit w/Hemi engine.

This hose is located directly under the engine oil fill port in the valve cover. After an oil/filter change while refilling the engine with fresh oil, this fresh oil will back up and overflow into the emmisions hose that leads directly to the airbox soaking the air filter with oil!
