Should EGR be avoided at all costs?
I'm looking at a 2002 Gillig Phantom transit bus. The miles are very low, in part because the Detroit 50 EGR engine caused issues for the transit agency (unclear in exactly what way). I really like the bus, but this forum worries me about buying something with EGR, since there are people willing to commit federal crimes just to remove them!
A general google search about EGR seems to indicate that yes, EGR is annoying and probably not the best idea for an engine, but if you start to see symptoms such as bad smells or poor engine performance, repair costs don't seem insane (well under $1000 from what I've seen).
Thoughts? If you found a bus that ticked all your boxes but it had EGR, would you still pass it up?
