OK here is the deal, I have the 89 yj 4.2. I put a valve breather on and then have put a filter directly on my carb allowing me to eliminate the stock air filter and housing, i have a few senors in the housing and was just wondering what to do with them, and also there re 2 lines that look about 3/4 inch that connected to the housing as well, any thoughts on what to do with these? Another thing is i have a tick at the front of my valve cover, can i fix this? are the lifters adjustable?
