2008 CM871 Smelly exhaust and surge

[LRT1549]

While were waiting for a smell description...

I've had a Timing actuator go bad before and the result was a slight hazing that really could only be seen under street lights. However there was always a strong unburnt (Raw) diesel small. When this was combined with oil from a leaking valve seat when the truck was cold it gave a kind of weird smell not to different from the old cats when they slobbered when running all night in the winter... For those that remember the classic smell of the old mechanical engines..
