I'm looking at a '05 coach with a 400HP ISL engine. I understand that the '05 & '06 years may have a problem with wrist pins. Has anyone here experienced problems with their ISL ?
As stated check the engine serial number. The warranty on the engine was was for five years.
My ISL blew (I mean really blew, a hole about 18x12 inches in the block) at 28,00 miles, with no warning and about one month before the warranty expired. Cummins covered the cost. The bill was about $30,000.
Personally, I would run from the sale as fast as possible.
