Sorry this is sort of long, but I dont want to leave anything out and give you guys as much info to work with.
Car:
95 240sx stock KA.
Background:
A few months back the clutch fan sent a few blades flying and cut the distributor harness plug. So I had to cut and splice in a new plug. I didn't solder/heatshrink it, I just crimped the wires in with some butt connectors as a temporary thing.
Later some motor oil had gotten on the MAF harness plug, and eaten away at the wires. So I had to do the same thing for that harness aswell. A week after I did that, my engine would die on me after 30mins or so of driving. I thought it was the recently installed MAF harness, but it wasn't. It turned out that motor oil had also gotten on the distributor harness plug, and messed up the contact where the butt connectors where. So I redid that again, and it eliminated the shutting off after 30mins.
Problem:
I thought all was well. But a few days after I fixed that issue, my motor once again did something weird after driving for 30mins. It would make a realy really loud clacking sound. It almost sounded like what my engine did once when it overheated past the H line (radiator had a leak I didnt notice). But the temp indicator was at the normal spot, and no check engine lights came on. I pull into a gas station and notice white-ish smoke coming from the exhasut side of the engine. I couldn't really tell where it was coming from. I couldn't go above 1Krpms with out the sound getting louder and louder. The RPMs would drop exteremely low and the car would die.
I was running late for work so I said "screw this", drove it (under 1K rpms) to work since it was about 10 blocks down. I parked it and went to work. When I came back out I started the car and all was well. I was driving back home, and again the problems started after about 30mins. Again, I drove it slowly home, and the same smoke was coming out the exhaust side of the engine. The next morning I turn it on for a 2 mintues, and its fine. But I know I couldnt drive it as the problem would surely arise.
Question:
Now can an irregular spark, sparking order, or whatever be causing this? I also have feeling that it could be the engine heat thats effecting the harness. Because it dosent do this when the engine is below normal operating temperures. Only after its been at normal operating temp for 15 mins or so. What can I use to properly shield the wires from heat and any other interference?
I just want to get it running okay, or atleast figure out the problem so that I can take it to a shop thats about 45mins away from my house where they can do the soldering/heatshrinking. I just think thats what it has to be (the harness) because thats the only thing I've been messing with lately on this car, if its not that I have no clue what the problem is then. :(
Thanks in advance.
