Common Issues With The Cummins 5.9L Block and Heads 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.
