I've searched and didn't find anything quite like this on here. I've got an '89 EA82 in a 4door wagon. This time last year I did a full timing kit that had belts, tensioners, idlers, and I added cam seals, crank seal, oil pump seal, water pump, hoses and a radiator.
Yesterday morning I started it and heard an extra little jingle coming from under the hood that I hadn't heard before. I popped the hood and saw the issue. It appears to be that on the oil pump pulley, there are rails front and back to keep the belt centered or at least on the pulley. The rail on the engine side has come loose/off of the pulley and is jingling between the pulley and the oil pump housing. I need to know if this is a major issue or if it can stay like this for a while without any damage. It seems I have to use a strap wrench or something to hold the pulley from spinning while I loosen the nut holding it on so I was unable to pull the pulley off tonight.
Please let me know! Thanks
