100K 100,000 miles Maintenance List
No need to change timing chain, or valve cover gasket (unless leaking) definitely not head gasket unless it is blown. PCV valve only needs changing if busted up. Can remove it and make sure it rattles.
good 100k tip: Remove the serp belt, and spin the tensioner pulley by hand. Also spin the one below it. If they are noisy/dry, replace them.
you could replace the bearing, but it will be difficult to source.
