Hey guys, well, I just got my car and I was messin with it the other day, and noticed a whole mess of oil in this one line running from the TB to the pass side valve cover. Well, I took off my tb today and wow, full of oil. I cleaned it out with some carb choke cleaner and got it looking like new again. I also got a breather for that hole. But now that end on the tb that is unsed makes this annoying asssss whistle when I go through the gears. Can I just cap this up or should I also fabricate a breather there? It feels like its bringing in air as opposed to letting it out. Any ideas? Just dont like the sound it makes and I wanna know if anyone else has had this problem. I dont wanna reconnect the line and have all that oil and sludge clog up the tb again. The inside of the plenum is pretty bad too
