oil in cold air intake
#2
This may be a stupid reply but is the filter that is on the intake one that needs oiled? I know my Steeda intake on my focus needs oiled and sometimes if you get to much oil on the filter and as it gets dirty you can see some oil in the intake. Just a suggestion not sure if it applies or not.

A cold air intake should have an oiled elements MOST do, however if thats a K&N intake or really anything but a S&B I suggest you remove that sooner than later because they dont filter too well on diesels and you run the risk of dusting your intake and if left long enough you'll have a dusted engine.
Now oil in the intake is normal because of the CCV . Take the cap off the oil filler and place it upside down. It should vibrate off, if it tries to float or the pressure lifts it up then you have too much blow-by. If it just vibrates off you're fine.
I suggest you look up the 6637 filter mod because cold air intakes don't have a good reputation on diesels, they end up doing far more damage than any gain from the "colder air" they get.

Oh! Oh!, Can I??????
Actually the K&N along with any of the Cold Air Intakes work just fine as far as function goes. We can debate the air flow, noise, etc at a later time. (or just dig up an old thread and read it) The only issue K&N has with regards to our trucks is the drop in replacement filter that goes in the stock air filter box. The rubber seal around the filter does not seal as well as it should. But, neither do some of the other filters, so, that's why many go for aftermarket solutions. The 6637 is a good, inexpensive solution.

You haven't read about all the issue's with CAI like K&N especially, on a diesel? Lots of people recommend removing them because they dont filter good enough. On a gas engine never heard of problems but I've read PLENTY bad about K&N. Enough that I'll never run one. Your motor your choice but personally I would not take the risk associated with them.
Its not about noise or airflow, its it's about the ability to filter even the finest particles that can damage our delecate compressor wheel first and eventually cylinder walls.
And you may be right to a point, a new filter will probably be fine but most people don't maintain them properly which leads to the problems.

Actually, I haven't read a thing about their CAI systems that are bad for diesels. I read a lot of hearsay, but nothing to back that up. There are plenty of choices out there, so choosing a different system is fine, as long as you like it. The only negative issues I have read about K&N that are proven, are what I stated above. But the factory filters have the same issues too. But, there are some guys that still have the factory air box, and have had no issues at all. It's just making sure the filter and box seal like their suppose to.

I really wouldn't risk it, and also k&n wont tell you how many microns it filters down to. Just a little fishy, if they were proud of their product they should put all the info out there so people can be sure that they are getting the proper filtering.
You have valid points I agree it's just that name brand doesn't have a good rep. Now AFE or S&B are some that I haven't heard bad about. Maybe just swap the element?

Back to our regularly scheduled program!
Joseph, are you talking about the Air-to-Air cooler? There is oil residue in the intake system of these trucks. It comes from the crankcase ventilation which is on the drivers side valve cover. There's a hose that connects to the intake between the air filter and the turbo. The oil will settle in the turbo boots that hold the piping together between the turbo, air-to-air cooler, and back to the intake spider. Finding oil in those places is common unless the CCV has been modified. Some have routed a long hose (oil resistant) from the CCV to down by the frame, and some even out by the rear axle. (should you decide to do this, be sure to plug the hole in the intake tube!) If that has been done, and all the oil in the intake system cleaned up, then you shouldn't find any oil in the system. If you do, then it must be coming from the turbo.
