PCV conversion
I saw a PCV installation on a Chevy 235 at the Wheelin Walla Walla car show last September. The road draft tube that vents the crank case has always bugged me – covered in oil acting as a magnet for dirt and road debris, and the inevitable drip of condensed oil from the tube.
So I instantly knew the PCV system (piping the blow-by and crankcase fumes back into the intake to be burned) was the perfect fix for me truck.
Installation took about an hour and a half, the most time consuming part was getting the stainless piping in the right position, which ended up requiring loosening the coolant hoses to reposition a few hose clamps.
While I was in there I tightened up a loose oil pressure tube fitting that was leaking.
