only about 50 miles on my new roxor ….it is a 2019 model with all stock.....seems to be a bit of engine clatter at higher rpms...….is it my imagination or does anyone else hear anything simiar? Thanks for the help.
I would have to listen to be sure but your probably not used to the noise that a Diesel makes during normal operation. Noise will vary with RPM and loadonly about 50 miles on my new roxor ….it is a 2019 model with all stock.....seems to be a bit of engine clatter at higher rpms...….is it my imagination or does anyone else hear anything simiar?

I started having clatter at around 1000 miles also. Took to dealer to check valve clearance. went to back and watched the mechanic and everything in speck. Now have over 6000 miles on it and still clatters, but no problems. I was very concerned also.only about 50 miles on my new roxor ….it is a 2019 model with all stock.....seems to be a bit of engine clatter at higher rpms...….is it my imagination or does anyone else hear anything simiar?

After I done a egr delete mine clatters more once I get to 40 mph, no matter what the rpm is. Should I reinstall the egr?ill pay atentiom to the tack tomorrow. we call it the 40 mph rattle. it happens at a few rpms at a low boost. nothing to worry about. all five or six? Cummings trucks have it. not going to hurt anything.
The fan has nothing to do with the so called dieseling at lower rpms. But changing to electric will add some extra hp
no. its a lean burn sound. by the factory tune. design? funny thing about a diesel. they run cooler running lean. compared to a gas motor that runs hot and breaks things. mine actually runs a lot better with the egr delite at speed. same with my 6.7 and 5.9. little better mileage out of the trucks also.After I done a egr delete mine clatters more once I get to 40 mph, no matter what the rpm is.

Thanks, that's the best explanation I have heard yet that makes sense. When I first got mine and noticed the different sound around 65KPH, a buddy said that's it normal for diesels to change sounds and I never really gave it a second thought after that, but there was no explanation why the major sound change. I have a John Deere tractor also and it doesn't make that sound change, but then it's not set up as a vehicle either.no. its a lean burn sound. by the factory tune. design? funny thing about a diesel. they run cooler running lean. compared to a gas motor that runs hot and breaks things. mine actually runs a lot better with the egr delite at speed. same with my 6.7 and 5.9. little better mileage out of the trucks also.
