Can you list how your lines are running to that can.
I see 2 lines but can't tell routing.

That's a good amount coming out after 30 min drive.

 

Yesterday I took the oil fill cap off while it was running and it was pulsing out smoke rings pretty good, so at this point, I'm going to say it's hurt. I'm going to pull the plugs this evening and do a leak down, but it's not looking good. I'm thinking about just picking up a 4.8/5.3 for the truck and then eventually putting forged rods/pistons in this 6.0 that is hurt later on down the road.

 

It did look like a train there.
But wasn't sure if you were venting your complete engine though that tiny filter.
But pulling cap off and puffing like that breathe was.
Engine has a good amount of blow by.

 

Yea thats a bit much...

 

I've got some strange results now. I haven't got to leak the motor down yet but I pulled the plugs this evening and there is no oil on them. There is oil on the threads but no oil on the electrodes. Another strange thing was one plug was gapped at .020 while the rest were at .040. TR6 plugs. Kind of strange but I figured a plug would be oily if the engine has blowby?

 

No not really depends how bad.

 

I just read on a different forum, "A blocked / malfunctioning PCV valve can give the same symptoms as excessive blow by gas due to the gas not having the ability to escape."

Is it possible that my pcv system is causing the gas blowby? When I checked it last night, the hose that runs from the catch can to the back of the drivers side valve cover wasn't even connected to the valve cover. There was another hose from the can that was very poorly hooked up, and I'm not even sure that the pcv system is routed properly. Could this cause blowby like symptoms? It's weird. The engine doesn't run poorly or anything.

 

How about this. Map out all your hoses and let us know how they are ran.

The amount of puff puff I see it's not Pcv.
Now hooking Pcv up will suck that into the intake through the catch can.
You would need a check valve in this set up as well.

 

A "pulsing out smoke ring" is a tale tale sign of a cracked/broken ring land. While the pistons isn't tearing it's self to pieces yet, it way down on compression and letting a bunch of compression past the rings and causing the "puff" of the smoke ring. I bet if you run a comp test, one hole will only have about 50psi of comp. I'm gonna go out on a limb and say its gonna be #7... lol

 

Well... Just ran a compression test and you were right. # 7 compression was 100 lol. I didn't check 2-4-6-8 because I decided to call it a night and it looks like a nightmare getting a compression gauge back there around the turbo manifold. Something interesting to note is that in #7, that was the only spark plug that had .020 gap whereas all of the others were .040. Just curious because this is my first boosted/high hp LS motor, what is it about #7 that you were able to guess that it would be that cylinder? Is that a weak point or something?
