Thanks, Nulu. The drill bit worked perfectly! The new tensioner seems to make the chain much tighter. I was concerned that the chain had stretched so much that the tensioner had just reached its limits, but once I bolted the new one in, the difference was apparent. I had to use a mirror to see the tensioner since it bolts in from underneath. The hardest part of the job (as I'm sure you know) was dealing with the brittle hoses on the air pump, which I deferred by unplugging and capping off until I can order all replacement hoses.

Anyone doing this job should order the breather hose on the rear passenger side valve cover since it will probably break on the way out. Also--and I was lucky I ordered it--the 110 degree elbow on the front driver's side valve cover broke too.
