If you drove a double breasted Yamaha for any length of time, your hearing would degrade anyway.
I not so fondly remember parking at a truck stop over night and having to park on the dirt or gravel because the 'puke tubes' puked oil constantly. You never changed the oil in s Detroit, you just kept adding. In fact Roadway used their Detroit's to burn used motor oil up. Had a metering pump that added drain oil to the fuel tanks as you drove along. Recycling before recycling was mainstream.
You want to talk about some sick trucks, Roadway had them in spades. You had to slam your fingers in the door before driving one.
The thing about Detroits was, they were really designed as a vocational engine, not an on road engine. They do best when run at rated rpm for hours or days on end, not the up and down rpm of a highway truck. Why the make excellent standby genset engines or engines in derricks or earth moving equipment where they are running a constant rpm. Outfit I retired from had a V12 Detroit powering their Generac standby genset. Had 4 turbo's and 2 blowers and it was a screamer. Had positive electric lube and when the oil was at pressure it started at rated rpm, what a hoot to watch the black smoke come out the twin straight 8" exhaust pipes. Once it was at rated rpm (I believe 1800), no more smoke, just heat waves.
Detroit's always sound like they are running at some ungodly rpm, but they aren't. It's the Roots type blower that causes them to sound like they are.
