Next, the front end. After the water pump, fuel pump, pulleys, and the damper are removed and shelved, the timing chain is found to be loose and floppy. However, it shows no sign of failure, being the tough double-roller type. Most non-HP original and replacement chains of this era used a nylon-coated cam gear, which eventually ended up coating the engine's internals with chunks of broken nylon. If a haggard nylon chain is found, the oil pump pickup will be packed with the remains and is best replaced.
