My 1998 Discovery had to have the engine block replaced as it had the dreaded #53 block which is a known as being defective. The coach only has 36000 miles on it but the Cummins won't do a thing as it is out of warranty. This gives me an extremely bitter taste for Cummins as they know that they built defective blocks in that time era. I replaced it with a Cummins RECon and with labor it came to over $18000. My advice for other is before you buy a coach with a 5.9 Cummins have some check it to see it has the dreaded #53 block. Does anyone on this message board have any advice for seeking some kind of settlement with Cummins? :blackeye:
