Is this ticking normal?

I want to say it's been there since I've had the car (which isn't long)...I've changed the IMSB ~500 mi ago to be safe, it's very quiet and you can't hear it with the doors open when applying throttle. Put my phone underneath the exhaust, mic facing up. The video definitely makes it seem a bit louder than it really is.

Sounds like lifter noise.

When was the oil changes last and what weight oil are you using?

Mileage? Driven in the winters by prior owner? My guess is bore scoring.

It's possible, 100k. The car was in the south though for its whole life before coming to me.

5w40, when i changed IMSB -- about 500 mi ago. The noise sounds like it's definitely coming from behind the wheels completely (doesn't seem like the imsb) but I'm having trouble identifying exactly where it's coming from..

Hi,

yes definitely is one hydraulic lifter, I have the same noise when not drive my c4s for more than 1 month, but after few minutes the noise go away, hi think is when the oil become at good temperature.

Justin,

I have had this issue and done a complete M96 rebuild as a result. I have no idea how anyone could say your noise is definitely a lifter based on an Internet recording ! There are many other potential causes. It requires careful diagnosis.See thread below. There are many similar ones if you search for "ticking" on this and similar Forums.

have you listened carefully to the CAT?  at idle a deteriorating CAT can make clicking sounds.
