6.4 truck engine - intake question
I had to remove the intake off my 2018 6.4 in a work truck. 2500 to be exact- vin “J”
Right behind the throttle body is a twist cap- so I twisted it. What’s it for? With the throttle body off I can reach in and feel a hole going from a passage in it to the plenum. The part that came out rattles likes pcv. Thanks! Syleng1
