That's one nice looking 240D. Congratulations.

The oil pressure could well be high if it's just been rebuilt but it should not stay pegged at 3 permanently I dont think. Is your idle adjust knob at max? (all the way anti-clockwise). If so, adjust it clockwise some and see if it comes off 3 at idle after a while. Mine will drop to just below 2 after it's warmed up and had a good run but it typically stays just above 2 most of the time at idle. That's with 220K on a rebuilt motor. I keep my idle adjustment about 3/4 of the way to max because of an annoying sideways shake if the adjustment is lower.

The center switch is indeed fan speed. The two on either side are the heater controls for the left and right side of the car. No heat to max heat independently.

Temperature should be around 85C. Mine runs at exactly that after I replaced the thermostat and radiator caps. The needle never quite leaves the top of the 8 in 85 on the temperature gauge. I belive that 90 - 100 is too high.

I'm not really sure what excessive speed is for these but I've been keeping mine below 70 as I just dont believe it's good to rev any engine excessively. Especially a rebuild with 220K on it. No idea what quality of work was done on it after all. But I will say that since I had my motor mounts, tranny mount and flex disc replaced a couple of weeks ago my car has smoothed out remarkably at speed such that it now seems to be quite happy being pushed above 70. I'm fairly sure though that I'll seldom reach 80 with it.

If you dont mind. I'd appreciate you letting me know if your car is equipped with engine mount shock absorbers. I'm trying to determine if mine is supposed to have them and it's also an 81.
