Had some squeaking from what I thought was a belt issue so replaced the tensioner and pulleys. Was finishing routing the belt through the pulleys when I noticed that the belt wasn't seating on the ridges of the PS pulley. Almost certain it's the problem with the OEM engine mounts having too much play when power shifting and was hitting the subframe (my car was produced in the last month these cars were apparently effected 04/2008). It got significantly worse because of big potholes and construction in my area. I read that some people's engine mount bolts worked themselves free from oil leakage, bad design, wear and tear, etc and was wondering if anyone knew if/what bolts to try to tighten up before dropping loot on the 335is passenger engine mount? Preferably would like not to have to lift the engine just to see if tightening the OEM motor mounts does anything
