Hey everyone,

Thanks for taking a minute to try and help a new guy here. My 350Z just started making this knocking noise? Temp is good, oil is good, just came out of nowhere. I uploaded a video on YouTube so you can hear it. Thanks for any feedback!!

Welcome and I saw your post at the "other" Z site. I agree it could be a bearing failure in the shortblock, but it would help to know some specifics like:


-How many miles on the VQ?
-What, if any, engine mods?
-Any other signs of powertrain problems before this noise began?
-Have you ever had a UOA done on this engine?

Hey Rob, my 2006 350z is doing the same thing. When I accelerate from around 1.5k - 4k rpms, it seems to knock its in all gears.
