I ask him the mileage he had on the vehicle when he discovered it was worn out. It is going on my list of things to check as I put more miles on my vehicle. Right not I am approaching 200,000 miles. After about 250,000 miles it looks like it is time to see what type of play is in the timer bushing.
I can also see a possible situation developing here. At around 300,000 the timing chain is stretched. The person changes the chain not thinking to check the Fuel Injection Pump Timer Bushing clearance. Some time down the road the Timer Bushing becomes worn and the Timer takes out Vacuum Pump and pieces of Vacuum Pump take out the new timing chain and possibly damaging other parts of the engine.
