Workhorse upgrades include:

This build includes:
– Full CNC blueprint machining, (bore, deck, hone, and line honed) – The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002″ for precise piston to cylinder bore clearances. We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block. We bore the block back to the crankshaft center line and hone the block to Ra 13 finish. The piston diameter measured to the nearest .0001″ matched to cylinder bores. The Cylinder block 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.

Common Issues With The Dodge Cummins 5.9LÂ Engine (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.
-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.
