Review on ACDelco CV1016C Professional PCV Valve by Christopher Todd

Revainrating 5 out of 5

Codes 3025 and 0420 reset!

I replaced the PCV and knock sensor on my 1999 2.2 liter Subaru and the trouble codes were cleared and I got rid of the emissions without changing the catalytic converter. Replacing this part is very easy. Before installation, I wrapped the threads with Teflon tape. The whole project (I also did the fuel filter) was done in an hour.

Pros
  • Stable Test Results
Cons
  • Updates
