valve guide ?

[C_Luft]

So I recently took the truck for a spin around the block (usually every other week), and it got me thinking about my issue with the passenger side head (valve cover pop), when accelerating or cruising no issue at all except injector knock but when decelerating I hear a pop from my valve cover (sounds like a bov) and then the engine hiccups and rpms go up for a split second, I think what is happening is my engine oil is getting past the valve guides when decelerating just after the valve cover pops and there for rpms go up from the oil, ,,,does this make sense to any one else

Also when cold starting (starts instantly) very slight white smoke from one or two bad glow plugs, but as the truck is warming up its increasingly blue/white and smells like a campfire as my buddy would say (probably from the crap injectors)

Do you know about the huffing noise these trucks can make out of the exhaust? Does yours do that?

Chuffs and huffs and whatever odd noises your experiencing definitely should not be ignored. Here's what it looks like when it sounds like the above video.

That sparkly sandy looking stuff.... is metal. The rocker was worn away, and you can take the valve stem and shake hands with it.

Uhmmm...ok after listening to that second video, I bring for your pleasure and reading this thread here http://www.oilburners.net/forums/sh...f-valve-breaks-POST-MORTEM&highlight=TECH+101

Read it and I'd strongly suggest pulling valve covers and inspecting very carefully inside each spring and looking for soot build up!

Thanks for the replies I will pull the valve covers tomorrow to inspect both sides and post up a cold (start) video with the passenger side valve cover off, and the second video is not my truck, I just came across that video thinking that was the huffing noise.
