Oil in my intake and intercooler piping?

Ive recently been adding some gauges to my 03 six liter, When I removed my intake elbow to drill and tap for the boost hook up I noticed an excess of oil sitting in the boot and covered down in the manifold its self. Just trying to find out if this is common or do I have something wrong or going wrong with my baby. Thanks to anyone who has some knowledge on this topic! Hugh.

Common, from my understanding it's part of the crankcase ventilation system, and that oil is necessary for proper turbo lubrication. Not really sure if it's necessary, as quite a few people reroute the ccv so that it doesn't dump oil into the intake.

crank case is more than likely overfilled.
egr trucks seem to like to be left a quart low.

a road draft/CCV reroute is not needed if the proper oil levels are used

Uh oh, Thats doesn't sounds very good. What do you mean when you say draft tube? Something I can fix to hopefully avoid needing the flame suit?

What is happening is that the oil that you see actually takes a long time to build up. It escaped the engine in the form of a vapor, but as the vapor cools, the oil drops out and collects on the interior of the piping.

Diesel trucks have been running draft tubes for forever and a day.
Soon enough, there will be some people dropping in here saying that by putting a draft tube on my truck I am harming my engine and warning not to do it for <blah> reason....

My take on it is this:
Don't try to get all fancy and run the line all over hells creation because you don't like the smell.. run it straight down. My draft tube is less than 36 inches long. Don't like the stink coming out of the CCV? Leave it stock.

Running it other than straight down can result in some serious problems like turning your engine into the most expensive oil fountain you have ever seen, and if that happens it will kick you really hard right in the wallet.

That should stir the pot nicely......

I did my own PVC relocate for around 60.00 bucks and my time. Itís on the driver side just under the front of the bed, looks the same as the expensive kits. The oil you see is from the PVC and itís going into your air intake just before the turbo, it is not a good thing It is not meant to supply oil to the turbo lol where do these guys come up with this stuff. Itís an emissions thing PVCís have been around a long time, but itís not a good thing with a high boost diesel like the 6.0. That oil will leak from your turbo boots and get in your air to air cooler. I know I spent many hours cleaning my after cooler after 8 years of not realizing how much oil vapors are sucked out though the PVC. This is a turbo charged engine so with the PVC going in pre-turbo guess what happens when you have high boost, sucks out the vapors at an excessive rate compared to a naturally aspirated engine. You wonít notice a difference in oil levels on the dip stick as this is vapors and over time it will put a lot of excess oil in a system that should not have oil in it. When I did the relocate I also pulled the air to air and degreased it on the inside and it was nasty it was never meant to have oil in an air to air cooler, and the turbo boots and tubes if you take them off without really cleaning them before reinstalling them you will blow a boot off with high boost and itís no fun pulling over just to put a boot back on. My cooler is much more efficient now and I have zero oil in my air to air system. Good luck just my two cents
