So the last time I took the intake off on my trooper, I noticed that there was a lot of oil puddling up in the intake. I pressure washed the intake and made it look like new but it got me thinking. I wanted to install a oil catch can or find a way to reduce the oil vapor coming into the intake. What I installed was a 3/8" air compressor water air separator(9$ ebay) in line with the PCV system to try to reduce the oil build up in the intake. Now I know the PVC system is there for a reason but the oil is collecting in the intake or building up in the cats and possibly clogging up the exhaust. After the install and about 1500 miles in I peeked into the throttle body and I noticed that no oil had collected and the inside was dry. Now I did notice that the inside had a light coating of grey powder but I imagine that is the exhaust gases from the EGR system but overall it was 99 percent cleaner with no oil build up. Also since my catch can is clear I could see the amount of oil that it was catching and drain it out as needed. At first I had to drain it out every 100 miles or so but then the interval stared to increase to the point were I just need to drain it every 1000 miles.
Any input on this would be great.
