Name that sound!

a little background - buzz test is ok, cont. test ok, no codes. oil pressure ok, if not a bit high. the noise increases with RPM, until WOT where all you can hear is the turbo scream.

it's the most clear while standing at the drivers side mirror, but my #7 cylinder is low on compression (300)

call it what you will, knock, skip, miss, whatever.

(sorry for the dark video, just took it)

Sounds ok. Is that cold or up to temp?

Sounds fairly normal. But with that low compression you do have an issue

that was driving the piss out of it after replacing the HPOP o-rings, so not fully up to temp, but close.

Have you checked the per/del numbers? I thought I heard a faint tick when you walked around to the front of the truck but nothing significant. I can't tell if its a ticking or fuel knock, I'd be concerned about the low cylinder though.

1. They are referred to as Change Rotational Velocity and I believe this refers to the percent of change in crankshaft rotational velocity after each injector fires, or another means of checking cylinder contribution.
2. I am not familiar with the Auto Enginuity system but I know a good scantool will show them while reading the data stream info.

I just read another thread where they said A/E will show that data FYI.
