Hello everyone.

I've been researching emissions and crankcase ventilation upgrades for my Duramax and keep seeing mixed opinions from different builders. Some say it improves turbo cleanliness and reduces oil buildup, while others argue it can introduce maintenance concerns and potential legal issues depending on use case.

Can anyone with real-world experience explain long-term effects of installing an l5p ccv reroute on a daily driven truck? I'm especially interested in whether it actually reduces oil in the intake system and if it impacts warranty coverage or engine longevity.

Any detailed feedback from owners who have done this mod would be appreciated here.

 

thanks in advance for any help
