I’ve been reading a lot about CCV delete on diesel and performance trucks and I keep seeing mixed opinions. Some people say it helps reduce oil buildup in the intake and keeps the turbo/intercooler cleaner, while others say it can cause pressure issues or long-term engine problems if not done correctly.

For GM diesel owners especially, has anyone here actually done a CCV delete or reroute on their truck? Did you notice any real performance gains, or was it mostly just cleaner intake components? Also wondering if it affects reliability, emissions compliance, or daily drivability over time.

Would you recommend a catch can or reroute instead? Would appreciate real-world experiences from GM truck owners. ]]> Performance zunepuh https://www.gmforum.com/performance-137/ccv-delete-gm-engines-%96-worth-just-risky-315669/
