i dont have the rubber hose like wats shown in the install my truck has the hard plastic piping...

 

Yea I can't remember what size it is like 5/8ish outer but just cut the plastic to the left and right of the stock tee and then slip some hose over it and onto a plastic tee and then run that out

 

^^^^ thats exactly what i did too

 

Old Reroute

Those of you who did this miles ago...do you still have oil coming down the back of your motor? This was an issue discussed in length on DP years ago.
I did my reroute in early 07..truck had about 10K on it and there was oil all over my intercooler tubes and dripping.
Now, 3 years later and 35K there is no visible signs of dripping on the driveway but every time I'm under the truck I think about whether the oil I see coming down is ever going to stop or do I have a oil turbo line leak...or more.
I don't have a good dealer that knows anything and the closest other dealer is 2 hours away. I know dealer would have gone after rear main but I was afraid to let them screw anything else up..which they have done..evidenced by my visit frequency the first year I had the truck..28X...
I don't seem to lose oil and my thoughts are since I never opened up my system to clean it that the oil is still seeping out.. I do run 5/40 syn and have since 10K.

 

Good point to bring up. I’ve never been a proponent of the re-route…one, because of the environment, and two, you’ll always have some oil there via the turbo, regardless of if the re-route is done or not.

 

I too am an avid proponent of being good to nature but logic would imply if the intercooler fills up with oil and continues to flow out on to the ground nature will not be happy...in addition, if we loose power with the intercooler not functioning optimally then we use more diesel...not good for nature...
Sort of like the fact the Prius has a larger carbon foot print than a hummer..sad but true.
I just wonder if it will ever clean itself out or should I; 1. bite the bullet and let the dealer mess with it or 2. bite the bullet and take apart the entire intercooler system and clean it out with fuel oil..yikes.

 

bump..................

 

i just did mine a week ago its awesome

 

Has anyone tried just putting an oil catch can in line with the PCV. I don't really want to be venting the crankcase to the atmosphere (not fond of the oil fume stink), but I don't really want too much oil in my turbo system either.

Just curious if anyone had done a closed loop catch can setup and how it worked?

Pics would be great.

 

Did my truck 6 months ago because of the oil running all over the intercooler pipe. Now it's nice and clean! I say well worth it and it's easy to do.

Would something like this work for the PCV Reroute?

JEGS 52205 JEGS Air Oil Separator

I was thinking something similar.

Should work pretty well as long as it has low air flow restriction and doesn't fill up too fast.

 

So what if you take the oil separator and route it back to the MP? Would this work?

 

That would certainly work too, I'm just not sure how much oil vapor would make it's was back to the turbo. It would be worth it for someone to try that setup for a bit and see how much oil (if any) gets in. If it's more than there should be, you could just vent the line instead.

 

does anyone have a picture of a LBZ with the re-route done, i am curious because of the limited movement of the plastic pipe and the space there is

 

so go with the 5/8 OD hose or go with the 1" shit? I should have read all of this post as well :booboo. Also will ID fuel hose work instead of heater hose?

 

Did my resonator block and pcv reroute yesterday! didn't really notice a difference in turbo noise thou

Finished mine on a lmm, used a 3/4" to 3/4" elbow and 1" steam hose. Bent the bracket for the sensor plug straight up and gave me enough room to clear it with large hose. Zip tied it to the fuel lines by oil filter. I have a good feeling about this because when I pulled it off the intake it was very oily inside. Oil + Turbo intake = Bad.

 

From what I understand from people who have done this mod is that they never see any oil dripping out of the PCV reroute tube. If this is true then that would lead me to believe that attaching the PCV to the intake actually tends to pull oil from the crankcase over time (most people who have tried the catch can/tank for the oil are surprised how fast it accumulates).

So I'm curious, does anyone who's done this mod see any oil dripping from the reroute tube?

 

By rerouting the tube to the atmosphere and not the intake you are removing the positive from the positive crankcase ventilation system. You will no longer see the amount of oil dripping from the tube. If you did a closed loop catch can then you would catch the oil in the can and let the gasses go back into the intake thus keeping the positive pressure on the system.

 

It's not positive pressure, it's negative pressure (ie vacuum pressure). Engines will run just fine when any positive pressure created from the engine internals are vented to the air. Instead the PCV system was developed to satisfy the EPA that oil vapors were not going back into the environment. The irony of this is that most heavy diesel construction equipment is still being vented to the atmosphere.

 

I realize this thread is probably dead, but has anyone successfully inserted an oil separator between the crankcase and the intake? Basically the standard reroute but bringing it back to the intake - (closed loop)?
The reason I ask is that I am planning on doing the reroute, in fact I've ordered the reroute kit. BUT it seems that an oil separator inserted midstream in the stock setup would be the best case scenario:
1. No "stink" from vapors under the truck
2. No leaking oil in the parking lot/driveway
3. Saving the Polar Bears :rockin
4. Maintian the stock negative pressure/vacuum on the PCV (whether we need it or not).

I saw that "Heron" had obtained the Racor CCV4500 in an earlier thread, but it died without any results or resolutions. That seems like an expensive solution but should be able to maintain the correct flow. I see other/cheaper oil separators out there but I fear they would end up restricting flow -- and I think everyone agrees that it a very bad thing.
PCV/Has anyone used the Racor CCV can? - Diesel Place

In the same thread, Tony Burkhard (of the now infamous "PCV reroute kit") mentioned he was working on something. That was about a year ago and I can't find anything else about it.

 

1. Ive never smelled any stink
2. Never seen any oil dripping
3. Polar bears are too far away to care
4. Thats a good question, never noticed any diff in how the rig runs yet.

 

Same here...

Although, it's cold enough here for polar bears now....I'll keep an eye out.

Do you know why GM has it going in to start with

 

Do you know why GM has it going in to start with

Emissions, plain and simple.

 

EPA emissions. Historically it just vented to the atmosphere like the LB7. But in the quest for lower emissions GM routed it to the intake to get burned up.

 

This might be a stupid question, but the re-route wont let moisture back into the crankcase will it?

 

No, that's a reasonable question but the answer is simple. Some condensation may occur as it does in almost any engine but once the engine gets up to operating temp, any water turns to steam and gets expelled through the PCV reroute.

 

Yeah that makes sense, I just didnt know if it would cause any more moisture than the factory set-up. Thanks man.

 

If you live in a high humidity area and are worried about moisture in your oil I would look into a by pass filter like the amsoil one or the fs2500, they take any moisture out. But as for the reroute its not going to make a difference.
