fuel injector ticking Q&A Review
Can a bad fuel injector cause a ticking noise?
A good fuel injector can cause a ticking noise, as well a bad one… Is that the issue with ur vehicle? Who knows, but the simple answer to ur question is yes, its possible.
What causes fuel injectors to tick?
Injectors ticking are not a problem and you can drive with confidence. Another tick could be from an exhaust manifold leak. As high-pressure exhaust escapes from a crack in the manifold or a leak in the gasket it will sound like ticking or clicking especially at idle or low engine RPMs. Source: gobdp.com
What causes that slight rattle or "clattering" noise that diesel engines produce? Even my modern 2018 car, although its very subtle, I can hear it compared to a petrol engine.
There are two components to that sound. One is the high-pressure fuel injectors. Because they have to inject fuel at nearly peak compression pressure, they’re working quite hard to do it, and make a pretty loud ‘tick’ or ‘clack’ each time they inject some fuel. Late models are a lot quieter, but there is a limit to what you can do with a valve that handles a few thousand PSI of pressure and has to open for only a few milliseconds at a time. The other is the sound of the very fast rise in combustion chamber pressure when the fuel ignites, which is way quicker than the pressure rise in a petrol engine. This is why diesels generally have to be built stronger. Late model diesels have more control over their timing, so they do this a lot less than earlier models, but there’s still some of it. Since diesel development is basically done, and they’re on the way out with the electric revolution, this is as quiet as they will get. Which is pretty quiet, they just have a character to the sound.
How the fuel injector cleaner works?
A customer books a service for his two year old defender. Mentions rough running and he had booked it in for new injectors at a time up centre who had recommended new injectors the following week. I asked if we could try a system cleaner we used available to the trade only. After the service I got a new fuel filter filled it with the cleaner. Started the defender, tick over was rough but we just let her idle as recommended and started work on another car. After five minutes the engine noise changed it began running quieter and smoother. The customer collects the car and we ask him to report back if he notices a difference. He was gone an hour, came back with a box of cakes saying it had never run smoother. That 20 pound extra saved 300 on new injectors and gave us a new regular customer. So yes the good ones do work but there are some that are cheap and nasty.
What was the most puzzling auto repair diagnosis you’ve ever had?
I've had 2. First was intermittent failure to crank. Check main power cables and earths and replaced starter with a spare from my £150 'donor', worked fine three times and then wouldn't crank again. Put a wire between battery +ve and the solenoid on starter and it cranked. Swapped ignition switch, again it was fine for a few goes and then failed again. I resorted to using the jumper wire until I had a weekend free. Tracked it down to aftermarket alarm relay in starter circuit, this had been mounted so it somehow collected water and it was quite corroded inside. Second was engine cranked but wouldn't start. Usual trick for flooding of removing fuel pump fuse and cranking till it fires up, jam fuse back in quick, didn't work. Removed crank angle sensor and coils, turning the cas got sparks on all plugs. Could hear injectors ticking when cas turned slowly, should be ok. Checked for fuel pressure by teeing a gauge into fuel rail feed, ok. Removed injectors, checked for flow, ok. Eventually I put a test lamp on injector plug and found the 12v supply would not light a 21w bulb but tested at battery volts on a meter. Checked at fuse and that could light the bulb. Consulted circuit diagram and found there was a 4 way splice in the loom. Unwrapped the loom, the splice fell apart. Remade the splice, engine started, re-wrapped loom. Took about two weeks of off and on testing. I have a spare car.
What problems could the clicking sound from the top end of my motorcycle engine be?
A Cam lobe gone down. Incorrectly adjusted tappets or even a fuel injector ticking. Or even the cam chain or belt slipping one or two teeth causing the piston to make contact with the valve head which is not unknown.
Does a bad fuel injector make a knocking sound?
Yes fuel knock can happen. Put a screw driver while engine running to the tip of each injector and your ear to the handle and listen for the difference in sound. A good injector ticks away a bad one sounds like a hammer. Remove the injector and hook it back up to its line and crank the engine. Watch the fuel spray. It should come out in a powerful mist. If bad it will just dribble or not work at all. Replace and your good
What can cause a slight ticking (valve lifter) noise in my car?
Are you sure its not fuel injectors ticking. If not, is the car high milage. Sometimes hydraulic valve lifters start making noise if there is sludge buildup in your engine and not enough oil changes or regular servicing or are just worn out.
What are the things in modern cars and power generators that weren't in older ones that make them so silent?
For Cars/Vehicles: Car exhausts haven’t really become much more quieter, except where regulations apply. Which means a Toyota Corolla hasn’t really changed, but Chevy Camaros aren’t rolling out of the factory with unrestricted V8s belching out the sound of the gods. Muscle cars generally have highly tuned exhaust sound, to give the throatiness of a powerful car, without the decibels. Where they have changed is in the engine bay. More intake restrictions and sound dampening chambers, with throttle-by-wire, you no longer need idle valves, which often make a loud hissing or sucking sound. Not to mention, the engine is quieter with higher tolerances, valve clearances, and knock control. Your average engine is so quiet, you can hear the fuel injectors tick. Of course, from 10+ feet away, most cars cruise making almost no engine noise. If you live near a highway, most of the noise you hear is from the tires and from the car ‘tearing’ through the air. The only exception is large trucks, and modified cars.
What can possibly be keeping a car (1993 Toyota Celica) from starting as the battery, alternator, and starter have all been checked and are good?
You didn’t say if it makes any noise when you try to start it. If no noise: a connection somewhere is bad? If ticking noise: solenoid? If it cranks and won’t start: distributor? Coil? Fuel injectors? Spark plugs? It’s flooded? Really, you need to provide more information in your question.
