Hello there. I have an '87 SE that I'm having some trouble with and wanted to see if anyone on here would know better about what's going on. I went to start it one evening and noticed the oil pressure gauge was reading at 0. It sat there for a couple seconds, then climbed all the way to 120 and past it. The fuel gauge was also past the full mark, battery voltage was where it usually is, and the temp was still warming up. I've had the gauges fluctuate before and the truck seemed like it was running normally so I drove it to where I was going, about ten minutes away, thinking they might settle down. Well by the time I get to my destination, the temperature gauge is also reading past the far right mark, and the truck is still running fine, but now I'm worried because I don't want it to actually be overheating. I looked it over once I parked and couldn't find anything odd, but I sat there and wanted to see if the temp gauge would cool down, and it did so pretty quickly. I decided to drive it home and tried running the heater to see if it might make the temp go down, but no change. Fuel, oil pressure, and temp all still reading past max and battery voltage still normal. I checked the oil and coolant; the oil was changed recently and looked a little dirty but normal, full, and the coolant was also full and bright green. I pulled the dash cluster out thinking maybe I might find something but everything looks clean and tight. After poking around on the common problems thread, it seems like someone went the three-pin regulator and solder the wires onto that route before me to replace a previous faulty voltage regulator. I'm not sure where to go next. Wiring is not my forte and I'm new to these trucks, please have mercy on me.

Mine is currently doing the same thing... leaking out of that little port. I have an '87 with drums; is there a way to differentiate between the MCs for the two?

Thank you both. The worst spot is under the rear seats... all the way through.

Hello all! My name is CJ (not a dude), I'm 27, and I live in the middle of cornfield central, Illinois. I just purchased what is technically my second Nissan truck, an '87 Pathfinder SE. The first was a short lived '88 hardbody truck, but that's another story... Before this, I've only owned Mitsubishis: '97 Galant, '91 Galant VR4, '90 Galant GSX, '89 Colt, and a first gen swb Montero for a second. I was actually looking for another Montero but this Pathfinder happened to pop up at the right time and not far from where I'm at, so a friend and I drove to check it out and here it is. P/O said this was his second one and seemed to have a soft spot for them, so took decent care of it as far as I can tell. It came from Massachusetts, but has been in the midwest for a while and as such, it does have rust. The body has 207k; the engine 130k. He relocated the oil filter and threw headers on it when the engine was swapped. It ran pretty well in my opinion on the two hour drive home. I'm not planning on doing anything crazy with it until I get to know it better and learn some more, so it's just daily duty/maintenance mode for now. There are some issues I'd like to get into and as mentioned, I've only had Mitsus so I'm very much a noob when it comes to these, but I am excited to learn and I'm hoping this forum and the fsm can help with that. It'll be nice to work on something again after not having a car for some time. Looking forward to seeing where this can take me!
