I removed my intake today and noticed that there was some engine oil in it. It looks like it is coming from the hose that connects from the intake to the engine. What is causing this? What do I need to do to fix it? What kind of harm would this do to my car if it continues? Thanks.
It's normal to have some but a bad PCV valve can cause an excess to the point in which oil consumption is noticed. You can check the valve just in case if you wish, shake it and if you can't hear the valve moving then it's stuck open and is bad.
Sounds like yours may be stuck shut or clogged not allowing the IM to pull vapors from the valve cover into the IM so instead it's pulling air in through the intake pipe when air should be going from the intake, through the valve cover.
are you guys talking about the hose that comes off the left hand top side of the valve cover ? if so what valve is there ? i just have a straight hose thats from VC to CAI let me know if im missing something
No and I already told you why, air is supposed to flow from the intake pipe INTO the valve cover and if it isn't its because the PCV valve is clogged and the vapors need somewhere to escape since the vacuum of the IM isn't pulling it through.

If tthere is too much oil then taht is a sign that the engine is in dire shape. To much oil in the intake means that there is massive blow by occuring and that can be a sign of bad rings. As fro your pcv check that first but be cautious as you dont want to much oil there.
^Yeah but figuring that vapors are being pushed forcefully out of the hose in which fresh air should be coming in from is more than likely because the crankcase is building too much pressure as the IM isn't relieving it, needs to go somewhere.

Catch Can or breather setup will help. The PCV system is very high velocity in the H22, so a lot of oil is burnt. This reduces octane and can cause some other slight performance issues. Even with a functioning PCV you will still be sucking oil.
I've run a catch and an atmospheric breather to help. The issue with the catch is it must be emptied once it begins to fill. It is also with a poor catch for the intake to pull oil from the catch at high RPMs.
One thing I have noticed for turbo cars is a high number of air oil separation products. These return the oil to the crankcase while sending clean air to the intake.
The only way to never burn oil again (unless valve stem seals or rings are bad) is to have a breather tank with the PCV system totally eliminated. Hole on valve cover welded over, nipple by oil filler removed and welded over. Sockets welded to the valve cover with large diameter hoses attached to a breather tank, the large diameter hose reduces the velocity of the air making it unlikely to push oil into the breather tank.

^Doing it that way you'll just get an enormous amount of blow by in the can as the hose is so narrow it will be forcing it out rather than pressure being relieved by the IM. Pretty bad idea, it would be better to properly burn the blow by gasses as they ARE NOT OIL.
Read the thread, OP is having oil forced through the hose near the oil filler that connects to the intake pipe, fresh air is supposed to be flowing in the opposite direction into the VC from the intake pipe. His isn't because the IM isn't pulling anything through because of a clogged PCV valve.

I had a mechaic look at this last week and he told me my PCV was not clogged. I didn't have time for him to look further into it because I had to go to work...
I don't buy it especially after reading the other thread you have your so called mechanic couldn't track down a simple oil leak on a Honda.
That was another mechanic lol. I stopped going to him for the reason that it seemed like he could not track down the oil leak.
I don't know man. The last mechanic that I took it to just took off my PCV valve, put one end in his mouth and his finger on the other end. He blew on it and told me that it was not clogged.
I waited 2 hours for him just to change the cam seal.
No and I already told you why, air is supposed to flow from the intake pipe INTO the valve cover and if it isn't its because the PCV valve is clogged and the vapors need somewhere to escape since the vacuum of the IM isn't pulling it through.
The less oil that makes it directly into the IM airstream, the better. I'm getting ready to build a dual catch can assembly that will scavenge excess oil vapor from both the PCV and general valve cover evacuation circuit.
After having removed my original valve cover to replace it with a newly powder coated one, it was all too obvious that the factory baffling is less than effective in suppressing airborne oil that ultimately gets pulled right into the IM air stream.
The catch cans should significantly cut down on this. Once I accomplish this mod, I'll post pictures to share locations and hose routing ideas.
