It does sound as though there is intermittent dragging. When you say it won't go into gear do you mean any gear or just first? Moving the gear lever to second then into first is an old trick on BMC gearboxes as you probably know. If difficult to engage any gear it could be the crankshaft spigot bearing (worn or high spot), slight damage to the splines on the clutch plate or shaft. I've seen both the latter cause intermittent problems including randomly not wanting to disengage. I can't see how the idler gear arrangement can be the cause. Apparently even dried grease can cause the problem.
Sometimes the car can be warmed up and I when start from a stop, I get the same problem and can't get it in gear. if I turn of the motor momentarily, I can put it in gear, then I turn the key back on and away I go. I've noticed this is engine speed related, because if the car is idling high, it won't go into gear. Sometimes I blip the throttle, the idle drops and it slides into gear. Sometimes it won't do the rest of the day, sometimes it does the next time I stop, no rhyme or reason?
I've always thought this was something in the drive train between the clutch and the gearbox dragging, but I think I'm wrong with that. I was thinking it was something like the idler in the 1100 motor, but I don't think the 1800 has the same system.
I too, am very interested in what the problem is.
