I got an 88 MJ. I think i may have a blowby issue on my hands and wondering if you guys could help me out. I have been trying to pin point a strange oil leak for a while and have checked almost everywere and seemed to find nothing. The other day i took the manche on a 15 min drive on the highway and stopped and when i did it smelled like oil..bad. so i opened the hood and noticed oil all around the oil cover area but not on the hood. I only notice the leak bad when at high rev's. I have an aftermarket breather on that seems like it could be a little loose and kind of $#!& really. I have a K&N cone filter so i l really don't have a place to plug in a good pcv hose. Should i just go back to stock air filter and hose or is there a better aftermarket breather i could buy that is better for highway use. Any input would be appreciated!! thanks guys

 

I would by a stock box. Probly the valve cover leaking.
