What is the pc valve and is it easy to change.

 

Positive Crankcase Ventilation (PCV) valve? Should be easy. Does it NEED to be changed?

 

It recomemnds being changed @ 30K but you might check it first before just going out and replacing it. BTW it is located here:

Your good you. You. Your good.

 

huh? why does it need to be changed?

 

If it gets plugged with dirt or sludge...If its plugged "blow by" gases can't escape the crankcase...

 

PCV stands for Positive Crankcase Ventilation. Essentially it prevents too much pressure from building up in the crankcase. Pressure will cause oil to be forced past the rings. So a gummed up PCV will increase oil consumption.

 

Thanks everybody for all your help.
