Click Click Boom!!!!!

Same as i hear here.
Too much horsepower with light loads...............=trouble.
Aldough here it is mostly boxtrucks and garbage trucks who have problems.

 

It was a 455hp truck specced for dry van hauling. It also had an apu.

The biggest def buildup I saw was a Badger hydrovac unit with a isx12. Kept throwing vgt mechanical position codes. Turns out the massive def buildup in the decomp tube was limiting exhaust flow to throw vgt codes. Icicle was a foot long.
The badger trucks are 90% loaded to maintain highway speed and 50- 70% loaded running the blower. They get worked very hard with only the 12l. No idea if this unit happened to get alot more idle time then standard.

 

That’s a Paccar engine

 

Man, some things just seem to run so good, so perfect, run their best before they blow.

 

It only came in for a check engine light...
