When does a car make a knock noise?

Why does my Ford F-150 make a knocking noise?
Donald, Found this info. from a Ford F150 forum, There are 4 electric actuators that control temperature (left and right), air recirculation, and mode. Try adjusting the controls one at a time to determine which actuator has failed. You may have to do a little investigative work to find which one is making the noise.
What causes a knocking sound after a warm up?
Knocking sound after warm up 1 Debris on the piston. 2 Rocker arms hitting the valve cover. 3 Piston to head clearance issues. 4 Valve adjustment. 5 Header exhaust leak. (double checked clearances and replaced the header gasket) 6 The previous owner of the heads told me they ran great on his car. I know he’s telling the truth.
Why does my Camaro make a knocking noise?
The most common things to make a knocking sound are exhaust leak (rulled out, we think) valve train (excessive clearance, either out of adjustment or leaky lifter, or flat cam) or a connecting rod lower bearing. A good clue here is that the noise happens when the motor warms up. The oil gets hot and thinner.
Why do I hear a knocking noise in my engine?
When your engine is running smoothly, the air/fuel mixture burns up in a single, controlled detonation inside each cylinder. Detonation knock is a knocking noise that you’ll hear when the air fuel mixture in the cylinders is detonating in more than once place at a time.

Another possible source of engine knocking isn’t actually coming from the engine itself at all. It could be coming from the accessory belt.

Why does my car make a knocking noise when I Turn on the heat?
This noise may be caused by an interaction between carbon that has formed on the piston, the piston motion and the cylinder wall. GM Powertrain Engineering, and an analysis of engines with this condition, has confirmed that the noise is not detrimental to the performance, reliability or durability of the engine.
What causes the kocking sound on start-up that disappears?
Depending on how cold it is or I guess long it’s sitting, I’ve heard it do it for about 30 seconds and then stop. Sometimes turning the steering wheel will cause it to stop or quieten it up until it completely disappears. Once it disappears, u never hear it for the rest of the day. As for the flex pipe, just look under the car at it.
