1. The LS-1 V-8 engine has very few hoses on its exterior, but the few that are left once an engine is removed from a vehicle will need to be pulled off the intake. This Gen III V-8 is an '01 LS1, but the entire Gen III engine family is similar except for a few hoses, wires, and sensors, so most of this info will apply to any Gen III V-8. You can easily remove these PCV hoses that connect the valve covers by pulling them off the valve cover vent tubes by hand.
