I would hope farther back, the DP get pretty hot when your towing up a grade

maybe some sort of slipover the vents in the TP ??

I'm working on a Venturi kit as we speak. I have the mpd CCv kit which is awesome , but the atmosphere is pretty hazy out the drivers rear .

LOL you guys are not lying. I have a constant haze coming up between my cab and bed. The truck pumps it out hard haha

Installed MPD kit today. Very nice stuff. Just did plastic cap on intake, next time it's off, I want to remove nipple and install a freeze plug.

was the fitting 12 orb x 16an
or 16orb x 16an?

1 1/4" wrench for both. I can't be for certain on sae side.

Is anyone getting oil drain/leaking when venting to atmosphere ?

Spindrift · Mar 2, 2014

I recall someone saying that the 6.7 slobbers quite a bit. I have no idea why that would naturally be the case since I believe bad seals and rings would be the contributing factors.

Keystone style piston rings shrink substantially with little heat. As in under 350 degrees F. By design.

Spindrift · Mar 2, 2014

Can I assume that is the type in our trucks? What's the purpose of a shrinking ring?

To allow for a better seal when they get hot when the truck is working hard.

It enhances long ring life in an engine. Were as rings used to wear faster. This style ring responds to basically two things. Heat and pressure. The more heat and pressure. The tighter the seal. It helps alot with cylinder wall wear when a diesel engine is idling. Allowing the fuel on the walls to be washed down with oil to keep things lubed.

In a nutshell

If the haze bothers you it is fairly easy to weld a 3/4 stub pipe into the exhaust at an angle. Then attach the hosefrom the ccv vent to the stub.
The capillary action will create light suction on the crankcase and the heat will remove the haze.
I have done this on several trucks and it was simple and worked excellent.

I think it will also help in racing applications where rpm is higher. Less crankcase pressure will improve piston speed.
This is common on drag racing setups in the gasoline world. google "crankcase evacuation"

I would be careful doing that without extensive knowledge and research. I have heard it can cause serious issues if not done properly.

Wayne did it on Erik's truck no problem, couple other guys have also done it no problems

Cratos · Mar 4, 2014

at what angle, and where in the system did you install it? any photos?

45° angle, with a 45° cut on the end of the pipe. The flat end when the pipe is placed at the angle should be facing downstream.

Should protrude into the pipe an 1/8 " or so right? When I was around a few bbc guys putting these in their drag cars they exlpained it to me that if it sits in the pipe flush with the inside wall it will create to much vaccum.. the farther you go into the pipe the less the vacuum.

Depth increases with exhaust pipe diameter. I cannot recall the depth for 4", but I believe it was around 1". Don't hold me to that, I'm not 100% on the depth.
