I may be wrong guys but I don't think you should be getting Oil in your intake piping. The only oil that may be leaking in to your intake pressure piping is probably coming out of a seal with in the turbo housing. Once you start pumping oil into your engine your going to create smoke in the exhaust and other problems. I know this is normal among older turbo cars where the seals have start to worn but not on a car so new. Let me hear some feed back on this topic from you guys. Sounds to me like a few guys may of rushed the break in period. Just trying to find out whats going on. :) :?:

I'm not sure of the plumbing on the SRT4, but I would imagine it would be some seapage from the turbo as well. Not a real good sign on a brand new car. A lot of times you will see oil in the intercooler from similiar problems. :(

you are reffering to the plastic tube that goes from intake box to turbo inlet?

The oil is coming from the tube that comes off the valve cover to the inlet pipe. It comes from the factory this way. There is nothing wrong with any of the cars. The hose coming off the valve cover releases pressure, along with that under higher RPM's oil can go through the tube as well. If you don't want oil in your intake you can buy a catch can or mopar performance parts makes a oil plug(like a check valve) that will release pressure but no oil it goes on the metal tube coming off the valve cover and it should work for the srt-4's as well as the other neons. I installed that on my 98 R/T because it was doing the same thing. So don't worry about it nothing is broken!

I was actually pertaining to the the High Pressue Tube Up pipe and intercooler piping. I did a little more research and found the pressure put on the engine under boost causes some blow-by( meaning oil passing past the piston rings recirculatiing ino the intake side) is a normal thing in turbo engines. Now when the engine is breaking in the Piston rings will set and hopefully elimnate most of this blow by. While breaking in the engine you may find a bit more especially with the synethic oil depending on how you break your engine in. Thats why these guys are finding oil with in there Up pipe when changing for the open atmosphere blow off valve. The catch can that greddy makes is an excellent idea if you are planning a decent amout of mods such that you don't pump any unwanted oil into your intake pleniuem because it will just bake to the walls and eventully be sucked into the head were it is later burnt and thats where we get the smoking exhaust. We all need to make sure and watch cloesly for have excessive amounts of oil residing in these pipes. Thanks for the replies.

Just to clarify, there is no oil going through the IC. It's only after the IC and it's coming from the PCV valve. Blow-by is never acceptable. If you have blow-by you need a new set of rings at least!

The reason I wrote this was because after readfing a few stories of guys checking there Up pipes they said they were seeing oil with in there up pipes. This is caused by blow by because the seals in the pistons when you break in the car are still setting. Most of this will go away after the first 1500 to 2000 thousand miles. Now there would have to be a small amount of oil within the Intercooler because in order for it to get to the Up pipe it runs through the Intercooler. Its mostly just a carbon gas that with a small amount of moisture which is a sample of oil. The PCV valve dumps the moistue gas into the intake side for recirculation. So its normal to find a little oil in the in the intake side that is pushed through the turbo and on into the Pressure piping all the way to the Intake Throttle Body. Its only really a problem if there are mass amounts of oil with in this tubing. A few drips really are not a problem. Break your cars in nice guys or this will be a big problem 60,000 miles down the road. Have fun and drive hard
