If clicking while trying to start then might be a bad starter. If clicking while running, then might be valve/lifter noise.
What causes. Clicking. In my left ear only
If it does it when you turn the key and the engine does not turn over, it is a weak battery or possibly a loose connection on the cables.
Possibally stuck lifters?
Driving at 50mph or above what causes a loud knocking clicking sound during acceleration?
your lifters are bad at least 1 of them or on a more serious note no oil in engine bad oil pump bad oil sending unit bent push rod blown engine
the clicking sound is the blinker. when you signal to turn with your blinker the light flashes and makes a clicking sound.
A clicking noise in the engine of a 91 Ranger could indicate a problem with the valves. A valve lifter in the engine may be worn or stuck.
Where is the clicking coming from? Within the engine compartment or inside the car?
That's what relays do when they are energized.
There are four causes of the engine failure. The four causes of the engine failure includes engine overheating, lubrication problems, misassembly , and detonation.
No its not from the fan motor, its from a stepper motor, which controls air flow to the drivers side footwell. The linkage for the motor breaks, and causes the clicking noise. There is a updated linkage peice that can be installed.
Detonation...Needs to be fixed immediately or will eventually destroy engine.
