Hi,
IS220 has 167000 miles on it and started to give me plenty of things to fix. The latest one has me stumped. The pulley on the tensioner keeps getting pushed off the bearing. Got a second hand tensioner and same thing. Have checked the alignment of the alternator to the crank and it seems good. All bearings and pulleys seem smooth with no wobbles. Marked the crank and looks like harmonic balancer hasn’t separated. Has anyone had similar issue or any ideas on what else I can check.
Thanks
