pcv valve?

i cant believe i actually have to ask this, but where exactly is the pcv valve on the 95jimmy?:banghead:

Center of the driver side rocker arm cover.

actually on a 95 its on the passenger side valve cover.

then what is that tube that comes out of the valve cover and goes into the intake tube on the driver side?

Thanks ZL1, minor detail ;)

The tube in the driver side rocker arm cover is the fresh air intake for the PCV system.

so when using seafoam through the pcv system, do i want to go through that fresh air tube, or through the valve itself?

Through the PCV valve.
