EA888.3 PCV Reinforced Threaded Insert Kit

The biggest flaw of the stock PCV on EA888 Gen3
Under high boost conditions, reverse crankcase pressure flows back into the turbo oil return line, impacting the turbo lubrication system, blowing out the turbo seal and causing heavy white exhaust smoke.

Upgrading to this embedded one‑way PCV valve from EM completely blocks reverse pressure backflow, fundamentally preventing oil leaks and damage to the turbo & crankshaft seals.
After installation, the turbo runs more stable with faster and more direct throttle response, ensuring reliable high‑boost performance and avoiding costly turbo replacement.
