My dealer just completed the 30k mile service on my 02' WRX. The service manager told me they could not replace the PCV valve (as recommended without removing the Turbo assembly. To do so would have added considerably more to the total bill for the service -- so he opted not to replace the PCV. Frankly, I don't see that Subaru mentions the replacement of the PCV in the online maintenance schedule (at least not at the 30k mile interval).
Does anyone know how frequently the PCV should be replaced on a 2002 WRX? Also, please advise me if it is necessary (as the service manager claims) to remove the Turbo assembly to do replace the PCV.
I will appreciate any advise you can offer.
