Excess Pulley Movement
 

Has anyone on here experienced pulley movement like in the video below. I had my car serviced for an oil leak by the timing chain cover. After the fix, I felt my car was significantly louder during idle. Seems like something is not tidied up here. Just need to compare to some other FRS/BRZ. Is the pulley shaking excessively compared to yours? Your input is much appreciated.

That's normal bud. The idler pulley. You're not the first to question it.

[pedantic statement]Actually the belt tensioner pulley. Idler pulleys are fixed in place.[/pedantic statement]

Thanks guys. I wondered if everyones shakes like this. My coworker who has an frs had some movement but not as much as mine. I wonder if this has anything to do with my idle dropping off and if timing can be modified to reduce shakiness.

You may wish to carefully inspect your car's serpentine belt for signs of wear.

Oops! Thanks, Ultra!

Hangs head in shame...:bonk:

lol

That's likely due to having the air conditioning/defrost on, it cycles on and off putting a load on the engine causing the idle to not be consistent.

If it happens with the AC/defrost off then there is a service bulletin to update the tune provided your car is a 2013/2012 build.
