Hi
I have an '84 318i that has been starting adequately when cold, but is suddenly subject to wild idle fluctuations and a jumping tachometer with in and out power loss while on the road. this appeared during the afternoon commute for about 3 miles in the middle of a 100 mile drive yesterday, stopped and came back near the end of the drive. the rotor, and cap were replaced since the rotor contact had broken off, and there is some slack in the distributor shaft.
This is a high mileage engine, and there has been a shoosing rattle like overone near the bell housing with blow by on the pistons that is apparent when I pull the valve cover cap. This sound now comes in when the idle and running rpms fluctuate. For the first minutes of curbside warm up it's okay, so I'm hoping it is not a cam to dist. gear problem, or bearing issue. Oil consumption had been normal, but I did have to add to the sump yesterday. Does anyone have suggestions or information about this?
