I opened my air filter and WTF is that?

[Austen]

I opened my air filter and found a foam sponge dripping with black oil. Why does the oil come down a small hose and into the air filter housing? Now I have to take tHe housing out and run it through a parts cleaner.

 

[Back-n-Black]

na just leave it. The crank case vent is the tube and it will always have oily air pushing threw it so no need to clean it unless you like cleaning a lot.

Im not sure that it should be DRIPPING with oil. Lightly soaked with oil is normal. It just filters air as it comes out of the crank case.. Which is full of oil..

Congratulations, you met Sponge Bob. I don't know about oil, but mine was pretty dirty. with odd looking stains and discolorations.

 

[HoosierJeeper]

I've never seen oil in mine...but then again never looked for it. I'll check later.....

It that foam piece is constantly dripping oil there is a problem,it's called blow by.It should take about 4-5 years for that piece to get enough oil in it to drip.

I think its right on that 4 year schedual. I just cleaned it and it wasnt as bad as i thought. We do not have a PCV valve right? Id rater put a fuel filter on the end of it.

Yes you do have a PCV valve.

 

[Austen]

So shouldent the PCV valve stop this oil? Someone has me afraid a ring might be bad. How do i know if its correct or somethings wrong?

You can install an oil catch can, use Fuel Filter FF733, then below that number is G485. They are at Auto Zone, and Advance Auto, one of the two or both. I used one for my Custom intake, since the breather hose goes into the intake tube AFTER the filter. The way they are setup OEM, is the breather filter is BEFORE the filter so no oil gets into the intake anyway... Look for pictures of my intake here, and see what I did...

Why would this condition leaad anyone to believe that a ring is bad? Rings are on the pistions, if a ring were bad then you would be losing compression and even seeing some smoke at the tail pipe. This may sound like a dumb question, but have you checked your oil lately? I knew one guy who did an oil change and filled er right up! AND I MEAN RIGHT UP TO THE TOP OF THE VALVE COVER! Anything is possible....But NO this is not an idication of a faulty ring!

You think thats bad, there is something over on lost about that stuff that makes me want to throw up. Its seriously messed me up for life and it should really be removed... But it seems its not going to be..

Jen and I read it early this morning!
Pretty sick!
Back on topic. I would think that you have major issues with your engine
if you have that much oil on that sponge.
Our has oil residue on it, but not dripping.

 

[kj924]

Yes this is a major indicator of blow by at the rings. With more than normal pressure on the crankcase, because of the blow by, the oil mist/vapours will migrate to this filter.........and when enough oil has migrated there, then you see evidence like the oil soaked filter. This is the first thing you should check when purchasing a used vehicle. That's why a good/sneaky used car salesman will always change those filters and PCV valves when unloading a lemon.

 

[HoosierJeeper]

Here's my "Sponge Bob"-

Not oily at all......

 

[AlexKJ]

I don't have that sponge... maybe a 2005+ thing...

 

[Marlon_JB2]

Nope. Ur sposed to have a spongebob in there..

 

[Searcher67]

I don't have one either, not even a place for it!

 

[ridenby]

dont either,took it apart just to see

 

[tjkj2002]

Nope. Ur sposed to have a spongebob in there..

Nope that is a '05+ KJ thing.My '02 KJ has 2 breathers that vent directly into the intake tube,no filters or sponges at all.

 

[Austen]

I dont have any loss of power or compression. I am about to change the oil soon. I will replace ol sponge bob this one time so i can gauge how bad it is.
