    91 SE Project.

    in 90-95 WD21 Pathfinders

    Posted · Edited by NavyP503

    Hi all,

    I keep putting off posting on here to keep working on my new Pathy. I bought a 91 SE-V6 Manual with 258,000 miles for $500 a few weeks ago with a broken timing belt and other little problems. Found a broken exhaust manifold stud, drivers side window didn't work, back passenger door handle didn't work from the outside, neither of the locks worked, and the interior was a bit of a mess, dented A/C condenser- front bumper- and lower radiator support. Tearing into the engine went pretty well, here's the timing belt:

    The broken stud:

    Dented A/C condenser, found a good use for an old scissor jack though!

    Big rust hole under the battery tray, hopefully going to weld a patch in later this week:

    The only damage I found on the internals was one shredded lifter, everything else was straight and smooth:

    I spent the next couple weeks getting the engine bay cleaned up and everything put back together, I went with bolts for the exhaust manifolds, so far they're working well I'm going to go check the torques on them tomorrow.

     

    Went to start it for the first time and it sounded like the starter was binding up, couple smacks with a hammer and it started right up. Idles smoothly, a slight knock right when it started, I suspect a lifter is on it's way to needing replaced and frees up after it gets some fresh oil on it. The only problem starting now is every once in a while it sounds like the solenoid doesn't pull the lever far enough and the gears don't mesh right. Rocking back and forth has worked so far to get it running. I'm thinking the solenoid is either not getting good power or needs a shim to pull the lever farther and get a better mesh between the starter and the flywheel?

     

    Monday I started in on the interior. Driver's side window regulator was shredded and the plastic clips on the locking mechanisms were both broken. I found a junkyard with at least four WD21's though that I've been pulling parts off of. The window works now, it looks like the original problem was the rubber on the guide folded in on itself and the window stopped until the cable broke. The lock barrel on the passenger side is broken though, key doesn't turn it anymore.

     

    The problem I found today though is electrical. The parking lights didn't work, traced it to a blown fuse. As soon as I turn the lights to parking the fuse blows. I pulled the rear combination lights and the front markers bust as soon as I turn the switch the fuse blows again. With the switch in 'off' resistance to ground is good downstream of the fuse, with the switch in either other position resistance is about 1 Ohm to ground, anyone know what the nominal is? I also found out this evening that the dash lights don't work. Headlights and turn signals work, dome light stays on all the time (unless switch is in 'off' of course ) and the reverse light doesn't work either. I've checked all the switches for the dome light and they work all right. I only have the Haynes manual for it so the wiring diagrams aren't the best. As far as I can tell I have a ground somewhere on the hot lead of the parking lights, which also leads to the dome, dash and reverse lights. I'm hoping someone else has had a similar problem because tracing out a single wire from front to back and behind the dash is going to be a PIA!!! Any suggestions are much appreciated! :D

     

    EDIT: Haha, Search FTW.... hopefully. Finally found someone with a similar issue, apparently a wire for the parking lights goes behind the radio. And I was fussing with the radio all day, big jumble of wires due to someone's shoddy install of an aftermarket radio and amp. I'll check it out tomorrow morning and let you all know. Good think I stocked up on the 10 amps today!

    Thanks! I kept getting various results from Google when I was trying to find out if it was an interference engine or not, guess I'll be tearing into it then :D More fun for me. Now if I can just get caught up with school so I have enough time to work on it.

    Hello everybody,

    Picked up my first Pathfinder today, 1991 SE... I think, still haven't quite figured out the differences. Picked it up as a project to get running, pretty sure it has a broken timing belt. I was surprised at how good of shape the body is in though, typical wear and tear on the interior. My plan is to tear out the interior on Tuesday and start tearing the engine apart on Thursday. It has about 258,xxx miles so I haven't quite decided if I want to pull the engine and rebuild it or not yet, any suggestions would be appreciated. I'm really excited to finally have a 4x4 though and can't wait to get it running. See you around the boards!
