6.7L Long Block Workhorse 2019-2024 Cummins Dodge Diesel Engine

SKU: CEP67CLW1924

CHOATE 6.7L Long Block Workhorse Engine 2007.5-2018 – Dodge Cummins Diesel Engine Manufacturer: CHOATE Engineering Performance CHOATE Part Number: CEP67CLW

The 2019 and up years are known as the dark ages for Cummins owners. They have been plagued with so many issues from Cummins that it has led us to completely revamp this problematic platform. After much R and D we have decided that it was best for the customer to start from scratch. The blocks were lightened up roughly 75 lbs lighter. The material removed was taken from the most critical parts of the block. This is all shown in the podcast link at the bottom of the page (full video). Cass spends over an hour talking about this engine, and just what caused the failures. Most talk about the camshafts that fail. But there are much bigger problems. Choate Engineering Performance restores the reliability you have come to know and expect from the beloved Cummins platfrom. Click here to jump to the part about the 2019.

      The main housing is honed to precisely align the crankshaft in the engine block. The Cylinder walls are bored 90 degrees over the crankshaft center line. The piston diameter measured to the nearest .0001 inch matched to cylinder bores. *(See Video)

      The Cylinder block for this Cummins is surfaced to a finish of 30 Ra or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket. *(See Video)

    Common Issues With The Cummins 6.7L Block and Heads (and how we fix them)

    Check out this video with Cass. He explains the issues and the fixes of the Cummins platform. (And How we fix them.)

Cylinder Heads- While there aren’t as many issues with the bottom end of the Cummins, there are really BIG problems in the head department.

Valve seats fallout contacting the piston and cause catastrophic failure. We machine oversize valve seats within creased press fit area to remedy this issue.

Stamped gallery plugs in the heads blow out causing a mixture of oil and coolant, destroying the bearings. We thread the head and insert threaded plugs to make sure this issue never rears its ugly head.

Plus: Freeze plugs in the block blow out leaving you at best stranded on the side of the road, at worst, with a severely overheated engine in need of remanufacturing. Every new Choate Cummins engine comes standard with billet freeze plugs that are blow out proof using a tie bar bolting them into the side of the block.

  • ***Warning!***

    The Workhorse Platform is built for the working man. Made to haul heavy. This is a man’s engine. Made to tow big stuff. If you don’t have callouses on your hands, or have a man bun, do not buy this engine. The exhaust this engine generates will blow the skirt right off your effiminate body. If you are a lumber jack, or need something to haul your traveling act for grizzly bear wrestling, this engine is for you. Built by Men, Made for Chuck Norris.
