When either the EGR or knock sensor malfunctions, damaging pinging and valve clatter [pre-ignition] can occur. Vehicles built after 1996 have an onboard system to detect such problems. Normally a check-engine light will alert the driver of failure in these systems. Even with all systems working and the proper fuel, vehicles can suffer from pinging, pre-ignition [valve clatter] if outside issues or wrong.
The noise is more noticeable when the weather is below 50 degrees. The engine knock may be caused by an interaction between carbon that has formed on the piston, the piston motion, and the cylinder wall.

On a carbureted engine you may otherwise find a run-on solenoid. The function of this part is to completely shut off the air intake at the carb when you turn off the ignition. If either of these devices is out of whack, fuel/air mixture can get into the engine after shut-down, causing run-on.
Engine was completely rebuilt 2 years ago (28,000 miles on Re-Built Engine/ 156,000mile on Van). Coolant level is SAT, Engine oil level is Sat. Van was driven 2800 miles since last oil/filter change.

Starts easy, warms up predictably and runs well. I did a gas station stop after riding about 45 minutes and when I came back out and started it up, on its first revolution, a nice firm "tick."

Complaint #10 – THE ENGINE SEEMS TO “PING” OR “KNOCK” AFTER IT IS WARM The first item to check is the base ignition timing. If that is correct, the electronic component to test, if your vehicle has one, is the Knock Sensor. An inoperable knock sensor will not send a signal to the computer to retard timing therefore pinging may result. 2. Turn the ignition switch to the ON position (Engine off). NOTE: • If the engine starts and runs, perform the following steps at idle. 3. Prepare the output state control function for actuators or relays that you are inspecting. 4. Vibrate the actuator or relay with your finger for . 3 s . after output state control function is activated. • Step 1 - Start the car. A knocking noise that only happens on engine start up for a few seconds might be a sign that the oil is bad. When s tarting a vehicle after a long period of sitting still (like in the morning before work), the oil pump has more work to do than normal. The most likely cause is a lack of fuel pressure from the fuel pump module. Carry out a fuel pressure check with the engine at idle and then ten minutes after switching the engine off. The pressure should be: 4 cylinder 1.8 2.0 380 kPa (3.8 bar 55 Psi) +/- 5% at idle and greater then 250 kPa (2.5 bar 37 Psi) after ten mins.
