2000 Trans Am WS6 - LS1 Power Plan - Pontiac Tech

Before removing the camshaft, the factory hydraulic roller lifters have to be pushed up into the lifter trays. A spare water-pump bolt is threaded into the end of the camshaft and rotated clockwise a few times until the lifters come up off of the cam and "snap" into the lifter tray. Specialty LS lifter rods are slid into the holes at the front of the block, which prevent the lifters from falling down once the camshaft is removed. Very rarely will a lifter fail to seat itself in the tray, but if it does, the intake manifold will have to come off to get the stray lifter out of the path of the camshaft. View Related Article
