After spending the last three weeks in Africa, and being around and in a lot of diesel engined trucks from 200-300Tdi and Td5 trucks, to Toyota diesels and Isuzu diesels from the same era, I can safely say that my truck is 2-3x as loud as anything I experienced.
Part of my loudness comes from the clank/ringing sound I?ve been trying to nail down for the past year. But in general, my idle noise is simply much louder than any other truck I know of.
This means that all my work to quiet the cab does nothing?unless I could find some way to quiet the noise actually coming from the engine bay. Dynamat does not do it. Carpeting and MLV mats do not do it. I can say that these things quiet the cab itself. They reduce rattles and echo, but in a very real way, it just serves to point out how much noise is coming from through the bulkhead from the engine.
But looking at my Range Rover and Disco, I wonder why I can not find the type of thick rubber matting you see in the engine bays of modern vehicles? I think this is my last resort, I just can?t seem to find stuff that I could use in the engine bay. Maybe I?m reading wrong, or not recognizing what I?m looking at on internet images? Any thoughts on really focusing sound muffling efforts on the engine would be appreciated.
