Wobble Noise at Idle

[idrivealawnmower]

Ever since I replaced the serpentine belt on my 2013 Honda Civic Si, there has been a wobble noise. Since then, I replaced the tensioner assembly, idler pulley as well as the pcv valve, but the sound still persists. The sound is only heard at idle and goes away while in drive. Is the noise from a bad crankshaft pulley or something else? If it is the crankshaft pulley, should I buy an OEM part or just go with Dorman / APremium? Thanks for the help

Can u put the old serp belt back on and see if it cures the problem?

If the noise started with a new belt, then it's probably caused by the belt. Might just be the difference between a worn belt and a new one. Since you have a new belt, idler, and tensioner, I'd just run it and keep an eye on things.

Put the old belt back on and see if it goes away. The new belt is soft enough to where it could resonate ever so slightly at low rpm's especially at idle since the rpm's can bounce by around 50 rpm. But this is not something I'd worry about.
