This is becoming quite the project...really didn't think it would need too much when I got it, but alas..."nothing more expensive than a cheap mbz"
Changed so far:
-AC Electronic Clutch
-Front Brake Calipers, Discs, Pads, Wheel Bearings
-Rear Brake Discs, Pads
-Rear Swa Bar Links (2)
-Oil, Oil Filter, Fuel Filters, Fuel Lines
Now on to the current mind-blowing situation, with my glow plugs. When I first saw the car, it was hard starting. I noticed that the glow indicator (italian parmesan shaker type, not the new w123/late 115 style) did not function. The car did eventually start after about 20 seconds of cranking. I took this to mean that "hey, engine/compression is so good, that even without glow plugs it's starting up". After the 2-3 days of sitting while doing all the above work, it would not start. New glow plugs time, why not?
Took out the old ones, and they were the upgraded, pencil type. I ordered some, and they were the correct loop type. So I obtained a used ground cable (1), used ceramic insulators (4), used resistors (3....two of the loopy ones, and the one longer one between 2 and 3). After a bit of massaging to make sure the wiring was correct and the switch was working correctly, the glow indicator lit up and it fired right up. Perfect idle. All good. Drove it a few miles around town, all good. Drove it home that night, then to my in laws'. When leaving after a few hours, got in the car, started it up, nothing! No glow whatsoever, and a starter hopelessly trying to start a cold engine. Damnit. Drove my wife's car home, came back the next day with new glow plugs, tools, etc. Took everything apart a few times trying to figure it out, and found that current was lost between 2 and 3 for whatever reason. Took out that glow plug, cleaned it, put it back in, and somehow, glowed and started right up. There was a bit of oil on the plug itself, and I'm not sure that this is normal. Most of the time I see these, they are a flat black color, and do not have traces of wet oil, probably because any traces would burn off when heating...right?
Without making too long of a post....I drove the car home that day, and just for kicks, after it sat for several hours, I tried to fire it up that evening. No problems...good. The next morning tried again........W$^@$%#!@^&#$. It's part frustration, part fascination. I really would like to figure this out.
Does the glow plug indicator not function with parallel-type glow plugs? Any advice on what direction to go in is appreciated. I have brand new resistors, ceramic insulators, and ground cable on the way from germany...slow boat.
