Always liked cummins, especially over cat since 2003 for many reasons.

However, my GF's cousin came over, and he works for a large city in mass transit. He said they bought 200 buses with the new cummins ISL engine, which is just the ISC apparently with different fuel injection. 2008 compliant.

In 3 months they've replaced 600 turbos. That's right. SIX HUNDRED! Apparently they load up with soot.

200 buses, 3 months, 600 turbos.

If I ever tell you guys I'm planning on buying a bus with a Cummins, somebody slap me!



:block:

I believe the turbo would be the part at fault.

Cummins has had issues with turbos in the past. i was at our terminal at tunnel hill, ga. and a team pulled out in a NEW volvo with a Cummins and 10min later she is walking back (he's waiting for the tow truck) they blew the turbo on the on ramp (the truck had 34miles on it)

It would be a holset turbo, and who owns holset? Cummins.

Still a turbo problem regardless of who owns them.

I think it is driver abuse. All 600 times.

I hope those turbo's were under warranty. I don't think it is an engine problem if the turbo is the only thing they are having problems with. But it does sound like they have a major turbo flaw.

Yes it's under warranty, but imagine the inconvenience of having a full bus and a turbo seizes up?

what model year are these engines allan? 2008?
