I posted previously here because I have various codes popping up on my car. I had a smoke test done on the emissions and it showed a leak at the pcv valve and hose assembly in the way back of the motor. I understand that in order to replace the pcv valve and hose assembly that the intake has to come off so that the assembly can be accessed. Can anyone clarify for me and also I need to know what the book calls for on hours to complete the job??? The motor is a 5.7L V8 and it is a 1999 SS Camaro. I have been told various things on fixing it so not real sure what really has to be done and if the intake has to come off or not???? You cannot see back there and I was wondering if a Chevy Dealer service center would have a better quicker cheaper way to repair this??? I was told or quoted approximately $478.00 for the fix in which the pcv valve and hose assembly would cost $109.00. It is running lean and have had codes for mass air flow, o2 sensors and various others like p0102, p0137, p0157, p0171 and p0174. The smoke test showed vacuum leak at pcv. Right now the service engine light is off but it comes on at least once a week and then a day later it goes off again by itself. Thanks JT

 

The pats you need arent that expensive. Get a service manual and you can do it yourself.
