Why does my diesel car sound so loud?
By default, diesel engines produce a louder roar than their gas engine counterparts. However, not all loud noises are normal. Possible causes of excessive noise include faulty rods, injectors, pistons, and valves. Loud noises may also result from low oil levels or if pressure in the engine is off.
How do you quiet down a noisy diesel engine?
Get soundproofing foam or a hood liner to install under your hood. A layer of foam under the hood can dampen the sound from a diesel engine. Check an auto parts store for hood liners or foam designed to reduce noise. Make sure the product is designed for hood installation so it can withstand the heat from the engine.
What causes noisy diesel injectors?
Injector “rattle” can sound like noisy valve tappets, or rapid machine gun fire. The injector could be fouled by contaminant, or is seizing due to inadequate lubrication. Sometimes a rattley, or pinging noise occurs under acceleration from cold, but will disappear after the engine warms up.
Why does my diesel engine sound like a tractor?

Why are new diesels so quiet?
The biggest reason the engine is quieter is the new common rail injection. The fuel is now injected into the combustion chamber at much higher pressures. With my system up to about 23000 PSI the pressure relief lets go at about 26000 PSI.
How do I stop my diesel injectors from knocking?
When you run diesel purge through your engine most of these noises will disappear within ten to fifteen minutes. The lubricant in the purge will reduce the “nailing” or hammering in the injectors and the clean fuel will reduce the combustion knocking sound.
