Lower end (???) knock: added video
PVC was changed with MC part.
This was taken in the right wheel well. Can hear on left also. Been going on for as long as I can remember but thought I would see what everyone thinks.
This truck has never ever given me issues other than right caliper bracket bolts always backing out and the manifolds.
Let’s try this video

Sir, It's not a knock from the lower end . I suspect it is in the valve train as I have a similar sound in mine. I treated mine with a tube of Xado revitalant designed for up to 10 Liters of oil. improves performance and runs quieter after 600 miles. the ruskies invented and pattened it for their piston hole swoppers over there. nano technology=good stuff. order from us supplier for faster service. caution engine oil must be at full operating temperature before adding. I have used this on more than 10 engines with amazing results. lasts 62k.won't fix broke but will sure fix worn.

Audio is a little faint but, knocks can come from all over the motor. It is a process of elimination at this point. If your certain it's in the bottom end what you are hearing is possible rod knock, especially if your hearing it from both sides. #4 #8 cylinder are notorious for going first.
