Diesel engine popping back through the intake. Watch how a bad camshaft can affect your engine?

I'm glad that ingersoll right impact worked for you. I bought it as soon as it came out and it broke in a few months of hardly being used. They gave me a hard time about repairing under warranty but finally did it - gave me some blah blah about usi g dirty air compressor at our dealership. Fixed or gave me a new one I can't remember because it's been around 10 years ago or more and that one lasted right until the warranty gave up. Later I saw they had a recall on them but I threw the thing in the trash already. A lot of money just to throw in a landfill.

hello in this case the popping sound would be permanent right? I have a Jag F-Pace 2.0D that had the same popping into the intake but it happened twice that it was running normal, no backfiring popping sound, so I guess it is not due to the camshaft being worn out right? could it be the hydraulic lifters or some electronic/sensor not working right? it runs well, engine check never came up, also no reoccurring fault codes, only had an EGR related code that I erased and didn’t come back but I also cleaned the DPF to make sure…any helpful opinion would be highly appreciated as I’m afraid I might take the emgine apart just to realize it was something else😅

Wow that #4 is toast. So what’s happening here is that the piston has already created vacuum in the cylinder before the valve opens causing a rush of air at once to flow through the intake, in turn causing the noise?

[@AllanHendrix]

The exhaust gas is not fully evacuated from the cylinder, so when the intake valve opens a rush of exhaust flows past and produces the popping noise.
