I've installed an IC style vacuum/power steering pump set-up on my 89 motor. I was thinking about things and since the vacuum pump is a vein pump it evacuates the air from the vacuum system and then expels it into the crank case/engine.

Now do I need any additional venting for my motor now that there is addition air being pumped in to it? What do the 91.5-93 CTD have for venting? Just the one hose running down the drivers side rear?

 

The intercooled trucks use the same crank case breather on the side of the tappet cover as the early trucks. No extra ventilation is needed for this.

 

Thanks, I thought so but wanted to be sure.
