Stop Blow-By. Protect Your Turbo. Simplify Maintenance.

Tired of oil residue clogging your intercooler and turbo inlet? The factory CCV system on the 6.6L L5P Duramax sends hot, oily vapors back into your intake, causing carbon buildup, airflow restriction, and long-term performance loss.

What is a L5P CCV Reroute?

The CCV (Crankcase Ventilation) system routes blow-by gases back into the intake. On the L5P Duramax, this setup can lead to oil buildup in the turbo and intercooler. Over time, it causes carbon deposits, intake restriction, and reduced performance.

Why Delete or Reroute the CCV?

The stock crankcase ventilation system forces hot oil vapor back into your intake. Over time, this causes:

  • ⚠️ Oil puddles in the intercooler

  • ⚠️ Carbon buildup in intake valves

  • ⚠️ Reduced turbo efficiency

  • ⚠️ Sluggish throttle response

SPETUNER’s solution: A high-flow, external CCV filter system with full block-off capability—improving engine performance, reducing contamination, and simplifying service.

Frequently Asked Questions about the L5P CCV Delete Kit

Will this L5P CCV delete kit fit my Duramax truck?

This kit is compatible with all 2017–2024 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L L5P Duramax engine. It is not compatible with Cab & Chassis models (3500/4500/5500).

4500, Will this kit trigger a check engine light or fault code?

The reroute kit typically does not cause codes. However, full deletes may trigger soft codes unless paired with a compatible tuner like EZ Lynk or Mini Maxx. We recommend tuning if you're removing the factory CCV entirely.

How hard is it to install the SPETUNER L5P CCV kit?

Most users complete installation in 1–2 hours using basic hand tools. The kit is designed for DIY installation and includes all necessary hardware.

Is tuning required to run this CCV reroute kit?

No tuning is required if you are rerouting only. However, full delete setups may benefit from tuning to suppress potential soft codes and maximize system performance.

Will this CCV delete help reduce oil in my intercooler?

Yes. By redirecting oily blow-by gases away from the intake system, this kit helps prevent oil accumulation in the turbo piping and intercooler, improving airflow and engine cleanliness.

Can this kit be used on a stock, emissions-compliant L5P?

Yes. The kit is emissions-conscious and works well with stock or lightly modified L5P setups. No emissions devices are tampered with during installation.

Is this kit compatible with my Mini Maxx or EZ Lynk tuner?

Yes, this CCV kit works independently of tuning software and is fully compatible with Mini Maxx (V1/V2), EZ Lynk, and other common diesel tuners.

Standard: What’s the difference between reroute and full delete?

A reroute redirects vapors through a filter to the atmosphere, while a full delete removes the entire factory CCV system. Both reduce oil buildup, but delete setups may require tuning for code suppression.

Does this kit include everything I need for installation?

Yes. The SPETUNER kit includes the filter, block-off plate, hose, clamps, and mounting hardware. You don’t need to reuse the OEM spacer, though it can be added for a tighter seal.

Will this upgrade void my factory warranty?

Any modification to emissions-related systems could impact your warranty. We suggest checking with your dealership before installing the kit, especially if your vehicle is still under factory coverage.
