Just had my 1996 LS checked out for a Code 8 CEL (TDC Sensor) that's been on for a while. Mechanic reports that it's indeed the sensor and that they'd like to replace the distributor housing... for $595. I would consider doing this myself... would I need to get a timing light to use after the installation?

Other things they mentioned:

Thermostat sticking occasionally.
Clutch hydraulic fluid leaking from the master cylinder (replace master and slave cylinders).
Outer CV boots cracking.
