The lower is "stupid" "internet" "YouTube wisdom"

 

That's what I thought, but I like to learn. Therefore the question here

 

I rerouted my to the back of my truck via hose and my boots (4yrs old and 115K miles) are still like brand new. In that time I've had ZERO leaks/blowoffs in the CAC system. I'd like to have a nice catch can set up but it's further down the list.

I had mine routed out near the rear axle for a couple of years. Finally got tired of smelling it and reconnected it. Never had any issues related to the re-route.

 

Our old buddy Bill is not entirely wrong about the CCV system and turbo oil usage -- anything that causes undue pressure in the crankcase will make the turbo seals more likely to pass oil -- as well as gasket and crank seal leakage

Undersized vent tube, excessive blow by, or just the length of the vent all play a role in crankcase pressure

The factory system creates a vacuum on the crankcase(depending on air filter restriction), which helps pull moisture from the crankcase as well as lessening oil leaks on the engine
it has long been known that a vacuum on the crankcase is beneficial

A catch can system would be a good addition to the system, but otherwise leave it factory

If you are getting oil out of the ventilation system, there is another problem that needs addressed -- changing the CCV is only a band aid

 

One thing I have to add -

Good 'ol Bill didn't mention that a properly done CCV re-route would be just fine. He just said that you would have problems w/ a CCV re-route.

One thing about forums - maybe we should have a note at the bottom of each post .....

"All repairs and modifications need to be done correctly to work properly". LOL.

Factory spec on maximum crankcase pressure is .3 psi or 8 inches of water.
