Its been a problem for a while now. before I use to get a tar like resedue on my stock air filter & box. The hose that comes out of the front of the 91 valve cover smokes like crazy. I now have a pipe w/ a k&n filter, but have located the vc hose somewhere else, Ive connected about 3 ft of heater hose to it & tucked it under my engine bay. How can I prevent this? I had the hose connected to the k&n pipe at one point but my idle ran low untuil I disconnected it.
