Do these trucks have a p c v valve, if so where is it situated.
thanks.

@AD On the K74's, Don't think it's a valve as such, the crankcase simply vents out through the rocker cover and straight back into the intake pipe between the filter and turbo, there is a baffle plate on the inside of the rocker cover to prevent oil splashing into the pipe though.
Someone correct me if I'm wrong.
