Id agree to that.now with the epa wanting these trucks to get 20 miles to the gallon or more Cummins is up against the wall so is Ford or any other diesel motor manufacturer caterpillar no longer produces over the road diesel engines they said they can't be madeto get good enough mileage to make the EPA happy and still be a durable motor.

for large trucks i will agree. i have never seen a cummins turd of an engine under 9 liters that was worth anything but scrap metal.
that is my reasoning for calling then cummings. because like the spelling they are both just wrong.

What about the infamous "Block 53"? Cummins did allow it to be made even though it never really met specs.

never heard of "block 53"" unless you are talking about one of the V8's they built back in the 70's
the 555 and 903 cummins V8"s were high rpm noise makers. no power or torque, but boy did it rev, and make noise, and drink diesel fuel. kinda like a detroit.

"Block 53" were Brazillian built 24 valves. It was when Cummins came out with it in around '99-01 is when "Block 53". These engine blocks were made thinner than original Cummins' specs and have a nasty tendency to crack.
Here's a link to a better description of them and how to fix it: Cummins #53 Block Info

LOTS of info out there on the 53 blocks. A quick google search will give you enough reading for a week.
Yup, they are one of the few cummins things to avoid. Still, there's enough info out there on how to identify, etc. that you can easily avoid them. Or you can buy one for cheap & put the pump & parts on a non 53 bock & have a great motor for less than what many people spend.
