Did the 1989 Jeep YJ 4.2L engine come with a belt tensioner assembly? Mine didn't, and if they did, I am having a hard time finding one. Thanks.

I have just replaced my key cylinder and am putting everything back together, but I am having trouble installing that metal arm that goes from the Turn signal switch assembly, and the turn signal arm. This small metal piece screws to the turn signal switch assembly in the eleven o'clock...

I have a 1989 Wrangler YJ. For a while I was able to turn the key clockwise all the way to the stop, and it would start. Now I get nothing. The ignition switch on the column as well as the cylinder are fairly new. I had to replace the headlight dimmer switch which uses the same mounting...

I have a 1989 YJ. I recently had to change the hi-low headlamp switch on the steering column. Though successful, I now have a new problem. Now, when I engage the key in the ignition switch, I have to go all the way to the stop, before it engages the starter. Today, I had to practically...

I had a massive exhaust leak and am in the process of replacing the manifold(s) gasket. My question, since everything is clean and decked, should I use a "gasket maker" to ensure it doesn't leak, or once again just install the gasket dry? Thank you?

I have a 1989 YJ with a 4.2L engine. In the early morning , it starts easy and the RPM's come up right away. But after a minute, it idles so rough, it sounds like it is firing on only 4 cylinders. After it gets up to temp. (approx. 170-180), it runs fairly decent, starting out, and fine at...

Does anyone know why my engine / exhaust is “spitting out” black water and smoke, and sticking on my driveway? It starts easy (89 yj), then runs rough until at 180 degrees, then runs great. But when stopping and restarting it starts hard! I am running 3.5 psi on fuel, and 11 degrees BTDC! HELP!!

That is a possibility. I will check it out. Lots of fumes in the cab.

I finally set the timing correctly on my 89 Wrangler 4.2L engine. It is an ATK rebuilt, with Clifford Performance intake/Weber carb/ and split headers. I milled the heads 0.60 , and added a Howard cam. I am also running MSD ignition. Now that it is timed, and runs great, the only issue I have...

I am having an issue with starting my 4.2l It will turn over, then hesitate, then run. I just “milled”the head .0060, and installed a Howard cam. It has more compression, and that may contribute to the hesitation, But i think it is more timing that anything else. HELP!!

Thanks for the information. I removed the rear track bar, and have an adjustable front track bar. I will take a good look at your recommendations to see if it helps.

I recently installed a "Tough country" 4 inch lift on my 89 yj. It rides like a "Buckboard". Can anyone offer suggestions to soften up my lousy ride??

Does anyone know where to buy the rubber "slave cylinder hydraulic line isolator/dust cover", that plugs the exit hole in the bell housing where the lines exit??? Ir is a small rubber grommet that keeps the lines from rubbing together and to keep debris out of the bell housing.

I just connected the 4.2L engine in my 1989 YJ to my AX15 transmission, and when lowering it onto the front mounts the new bushings won't align with the mount holes. The bushings are approximately 3/4 inch back (toward the firewall) from the mounts. I am not sure what the problem is, and need...

I am having a helluva time re-installing my 4.2L engine to my AX 15 transmission. I have changed every angle on both the engine and transmission, and can't get the splines to line up, The transmission is in neutral, and I double checked the pilot bearing to make sure it fit. Since it...

Every person I have talked to about the internal to external slave cylinder conversion says it is well worth it. I bought the NOVAk conversion. My issue right now is that their installation instructions are geared to removing the transmission. I just finished a rebuild of my 4.2L engine, and...

Two lines.

I have 2 lin I have two lines coming through the Bellhousing, and can't find the grommet for them. I received the Novak Conversion yesterday, with the intention of installing an external slave cylinder, but am sending it back today. It was missing the slave cylinder and a couple of other...

yes Yes. The internal slave cylinder is such an ongoing "hassle", I have decided to buy The Novak conversion kit, and eliminate the problems I have had. Thank you for responding.

YOU ARE RIGHT! And that is exactly what I did late yesterday. Ordered the NOVAK conversion kit! It will be an easy install, because I have the engine out right now. Thanks for responding.
