WARNING: This page is about a different car, the 2002 GMC Sonoma and 2002 Chevrolet S10 Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The camshaft is steel. The camshaft is supported by five bearings pressed into the engine block. The camshaft is of an assembled design with each lobe, journal, and the oil pump drive gear assembled onto a hollow tube which is then expanded to hold the components in place. The camshaft timing chain sprocket mounted to the front of the camshaft is driven by the crankshaft sprocket thorough a camshaft timing chain.
