Hi All,
I took this video this morning, I had little time to do the video as I had to go out and unbelievably it was very hard to pick the sound up. In my opinion, the sound can be heard from say 40 seconds into the video. It's seriously hard to drown out the turbo spool and tapping of the hydraulic lifters and focus on the dull thudding noise when I'm recording at the engine but hopefully it's clear at 40 seconds, someone can hear it.
