            DOES NOT FIT!!!

            Really frustrated that I missed another review saying the same. This does NOT fit on a 1989 YJ with a 4.2. The instructions in the box say it only fits early 80’s cherokees. The bolt holes are off by about half the width of the bolt to fit. It is also a good 2 inches taller so it may have clearance issues but didn’t get that far since I couldn’t bolt t down.

            Really nice valve cover! Much better than the stock plastic junk. With a small amount of modification this val ve cover should last the life of my Jeep.

            Will not fit 87 and newer YJ

            Despite what extreme terrains discripstion shows this does not fit 87 and newer, surprisingly enough it's on the first page of the instructions provided. If I had an 86 or older 4.2 I would definitely purchase its is a nice looking cover. That being said I am still waiting on extreme terrains to send me a return label.

            Looks good

            Well made, heavy duty, fits great, came with gaskets, bolts and gromets.
