I did that exact same install with AZ parts 3 weeks ago (same cap, rotor, plug wires and spark plugs you show in the picture). My jeep ran ok before, but runs really smooth now. I think the biggest improvement for me was the cap/rotor: my old ones had alot of built-up crud on the contacts.
Glad to hear it runs smoothly. My problem is the distributor cap coming off..... I'm going to work on that now!
Well the removal of the old one wasn't bad at all. I manually cranked the engine to the TDC (top dead center) which is the point at which the 1st piston is up. From there, I marked out the location of the rotor cap, and the alignment of the distributor itself on the engine block and the motor mounts with sharpie. After that came the removal of the C-clip that holds the distributor in, then the removal of the distributor itself which was rather easy. The C-Clip bolt is a 1/2 inch, which requires a box wrench as a socket of even the smallest size will not fit in the provided space. It took some PB Blastin' love to get that bolt loose.
I then went to install the new unit, with the rotor aligned. It wouldn't go in past the gear teeth, and would get hung up on the collar. A quick call to my buddy the mechanic and he said to lubricate it and "give it some love." So I lubed it and loved it, and it seated itself. Upon seating, the rotor moved a bit, but I had heard this was normal so I wasn't concerned. I put everything back together, and went to turn the Jeep on. It would attempt to turn over, but then I would hear and feel a bang- so I'd turn it off and ponder this. I basically then removed and re-installed the distributor 2 more times, each time trying to re-align the rotor to TDC via the crank shaft.
I finally gave up after the 3rd installation. Had it flat-bedded to my mechanic (shout out to Jay and John Weaver - 21 High Street, Reading MA - Weaver's Auto) and they said that each one of them has had problems installing distributors before and not to sweat it. They should be able to get it re-timed tomorrow. So here's the only picture I've got right now, one of the TJ being loaded onto the AAA tow truck. I'll come back and add install process photos tomorrow.
So the Jeep starts and drives. But it does so sounding like an 18 wheeler engine braking. I need a new exhaust. Muffler is in the worst shape of its life, and is rusted to hell and back. Monro muffler wanted $800 to replace from the cat back, as the cat is off it's hangars and has dents. Lou's Custom in North Reading wanted $570 front to back for whatever kind I wanted. Flowmaster, magnaflow, whatever. I'd like it to not be obnoxiously loud. I'd like a good throaty sound, but nothing that will wake up the whole neighborhood when I leave for work at 4 AM.Magnaflow, whatever.
What do you guys have? What did you pay? What do you recommend?
