Old air filter used with the turbo valve cover, stock turbo PCV system is used. 2000miles or so. This filter been outside the car a while and put next to grease parts but you can see where the filter is soaked with oil.
TBI valve cover and its oil splash guard is great mod to prevent oil all over the valve cover, air box, engine bay, and on top of the transmission. Don't even need a oil catch can.
I have a 88 daytona shelby z with a cast valve cover, had it since new (21 years now) and have always had problems with oil in the air box. I did at one point have the pipe from the valve cover going to a hose that just ran to the ground since it always got oil in the air box, hoses and intercooler.
well i just put in a new turbo after the car sat for 4 years in my garage because the original turbo had an internal oil leak and started smoking really bad. It is back together and I have it all plumbed like it is supposed to be-and am getting oil in the box again (on my K&N). I found online a Chrysler TSB about a fix that involved replacing the nipple on the valve cover. I ordered it, and when I removed the cover and took out the baffle plate, saw that the nipple I got was exactly the same-so I cleaned everything up and installed the new one anyway. The Dodge dealer also ordered me a valve cover gasket (one piece), and I installed it-it gets worse here, since the one piece makes the cover look like it does not 'sit down' on the head. I tried to carefully torque it evenly, to get it to sit flush on the head, and it, being cast, broke the cover on the left rear corner. I bought some high temp epoxy and glued it together again and went to an Advance auto and bought a new gasket (again, rubber one piece) and this time I did not crank it, but just seated it. It does not leak. I don't think I have solved the problem of oil getting into the air box since nothing has changed. All I managed to do was break the cast cover, and even though it is not leaking, I want to replace it.
What year cover do I need to look for? What gasket should I get with a cover that does not get oil into the air box? In looking at your photos, I see a tube up top that goes from the intercooler to the throttle body and it has a small air filter on it and some sort of vacuum diaphram-what is that? Also, there is a vacuum line from the top of the throttle body to the air box-mine in capped (been like that since new)-why is that vacuum line tied into the air box?
I started an earlier thread here with some of these same things, the only other subject i want to solve in the near future is, with the new turbo and wastegate, I only get about 5-6 lbs of boost, so I have a bleeder valve set up and am getting about 10-12 lbs of boost-but I hate that I have an open vacuum line going to the wastegate. I'd like to get that figured out too, but the oil in the box gets fixed first-along with a new valve cover.
Anybody having ideas, items to sell to fix or information, thanks.
