Review on High Performance PCV Crankcase Breather Valve for 💨 VW Jetta GTI Eos Audi TT A3 A4 2.0T 06F129101P by Jojo Howell

Looked like a defect Removed car, but noticed rough idling and occasional engine misfires after installation. When I tested this I found that the hose at the valve was loose and therefore causing a vacuum leak! I ended up taking the old and new valves apart and putting the new diaphragm into the old valve. replace the torn one. I put the old (reconditioned) valve back on the car and you know what; the hose fits perfectly. The problem appears to have been resolved and I now have a working Frankenstein PCV valve.
