Hi everybody,
Well, I made a rookie mistake on my 1987 740T. I changed the oil in the gear box (which was way past due). I put the bottom 13 mm plug back in. Then, I tried to remove the top 13 mm plug, which was rounded a slight bit. I couldn't break the plug free; so I thought, "No problem, I'll just bring out the vise grips." No go. The vise grip is just wearing away the brass nut. I tried a crescent wrench, pipe wrench, and vise grip again and again.
Any ideas? I'm thinking of drilling a hole and then using an EZ-out. But that EZ-out is hardened steel, and I suspect it will just eat right through the inside of that brass nut.
Before I drained the old oil, it was difficult to shift gears, even with the engine off. Now, with all the gear oil out, shifting is much easier.
But, I looked underneath the car and discovered I have a hydraulic clutch. Is there a way to adjust these? I see no adjusting nuts.
