Cummins Failures are no secret. Although they have been a very reliable platform for many years, they have evolved. And with it, they have developed some shortcomings that we see on a consistent basis. If you are interested in learning more about valve seat failures on the 5.9L Cummins engine. Be sure to check out the video at the end of the page. Choate Engineering fixes these issues and is known for making a good platform, great. And saving the customer money as well as down time.
This 5.9L Cummins Long Block Reman Engine Model C 2001-2002 Includes:
Upgrades over the Model C that are in the Daily Driver include but are not limited to:
Common Issues With The Cummins 5.9L Block and Heads (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.
Building engines the way the OEM factory should have in the first place.
