Why is my turbo making a ticking noise?
All engines have a small amount of ticking from the fuel injectors, which is also normal. It seems that more-expensive four-cylinder turbo engines are also having oil consumption issues.
Do turbos make a clicking noise?
The ticking is definitely the wastegate. It’ll be even louder if you took the heat sheilding off the turbo, as that provided some sound insulation. The boost spiking is probably caused by changing bits in the exhaust like a downpipe without EM, as that changes what the wastegate duty cycle needs to be.
Why is my car ticking when I turn it off?
If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn’t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!
Is it normal for a turbo to whistle?
A “turbo whistle” usually indicates a worn and failing turbo bearing, which is pretty much all there is to go wrong with a turbo.
What is Turbo knock?
Engine knock or pinging occurs when a separate pocket of air-fuel mixture ignites after the spark has ignited the air-fuel mixture within the combustion chamber. The fuel-air charge is meant to be ignited by the spark plug only, and at a precise point in the piston’s stroke.
Why does my car make a ticking noise when I idle?
The purge valve on your car allows fuel vapors to be burned by the engine for emissions purposes. This valve will make a ticking noise at times. Likewise, positive crankcase ventilation (PCV) valves can tick or rattle at idle. The fuel injectors on newer vehicles can also be loud and make a ticking noise.
Why does my car make a clunking noise when I Turn on the engine?
Place your foot on the brake with the engine in neutral and idling. Raise the rpm slightly over idle. Put the shift selector in drive, while maintaining pressure on the brake. If you hear a loud clunk, or feel a chassis shudder, this could indicate that the torque converter mounts have disconnected or broken.
Why does the fuel injector make a ticking sound?
Fuel injectors are small electrical valves that make clicking and ticking sounds when quickly opening and closing at idle. Ticking of the injectors is normal and you can drive without any worry.
Why does my torque converter make a noise when I drive?
Since the torque converter pump, stator and turbine spin freely without engagement during neutral or park, the noise will not be present in those settings. Accelerate slowly in drive and listen to whether the torque converter noise will get quieter as the vehicle moves forward. Place your foot on the brake with the engine in neutral and idling.
