How to Replace a Cummins Diesel Exhaust Manifold Gasket

The exhaust manifold transports the extremely hot gases produced in the engine’s cylinders to their next destination. In the case of trucks equipped with a Cummins diesel motor, these fiery exhaust gasses are routed through the turbocharger and out of the system through the vehicle’s exhaust pipe. If a Cummins-equipped truck is suffering from an exhaust leak at the manifold, but the manifold itself is in proper operating condition, the cause of the leak is often a faulty gasket.
Park your vehicle on a flat surface. Raise the hood and prop it open. Allow the engine to cool completely. Disconnect the turbo and any additional items, such as exhaust gas temperature sensors, that may be connected to the exhaust manifold. Do not remove the turbo itself; simply disconnect it from the manifold. Remove the manifold heat shield by loosening the four bolts holding it in place.

Remove the bolts that secure the exhaust manifold to the engine head, using a 13 mm deep socket. Store the bolts in a safe location, as you will need them for reinstallation of the manifold.

Clean the exposed surfaces on the head of the motor, turbo and exhaust manifold using a clean, lint-free rag. Installing the new gasket onto a clean surface will help ensure a tight seal and reduce the risk of exhaust leaks.
Coat all of the bolt holes where the exhaust manifold attaches to the engine, using an anti-seize product. Repeat this process on the mounting holes for the turbo on the exhaust manifold. The application of anti-seize will help ensure that the bolts are manageable during any future repair work.

Line up the new exhaust manifold gasket on the exhaust manifold itself. Slip the exhaust manifold and gasket into position against the engine and replace the 12 manifold mounting bolts. Secure the manifold in place and reconnect the turbo to the manifold gasket. Secure the heat shield and any additional sensor components that you removed during the course of the gasket installation.

Torque the exhaust manifold bolts to the specifications listed in the owner’s manual. Test drive the vehicle and check to see that the initial issue has been remedied by listening and visually inspecting for exhaust leaks at the manifold gasket.

Dodge Diesel Performance

The Dodge Cummins diesel is a favorite of many diesel enthusiasts because of how many modifications can be done to it. The Dodge Cummins diesel comes stock with great power and fuel economy and can be tweaked to get diesel fuel mileage in the upper twenties and some even report low thirties in mpg. That is phenomenal economy for a truck. They can also be turned into ground pounding monsters. Today we will take a look at a few of the modifications that can be done to make the vehicle either more economical or more powerful.

First the most popular modification for any diesel is a performance chip. These come in chips, modules and programmers. All have the same basic functions although they will all alter the fueling in slightly different ways and have a variety of safety features. Generally for a conservative driver, with almost any diesel chip about three to four mpg increases can be achieved. Most of these chips add about 120 horse power on their top setting. There are some extreme chips though that will add about 230 hp and over 400 torque to the dodge Cummins diesel.

Probably the second most popular modification for the Dodge Cummins Diesel is performance diesel fuel injectors. Upgraded injectors can also add economy for a conservative driver. The injectors come in stages that range from 50 hp to 150 hp over stock, and even more extreme injectors can be custom made. 50 hp injectors would be for someone looking for a little more power and better economy. 150 hp injectors would be considered extreme. They also come in complete injector replacements or just nozzle or injector tip upgrades.

For any diesel that is being modified, a higher flow exhaust should be added to help it keep exhaust gas temperatures down and to relieve engine stress. Most people upgrade the size of the entire exhaust from the turbo. Others use the Aero Exhaust which is a muffler replacement only. The design of the Aero Exhaust increases the speed of the exhaust like a jet would as the exhaust flows through it. On the 2005 Dodge Cummins diesel the Aero Exhaust adds 19 hp and 38 dyno tested torque by just replacing the muffler.

Another popular modification is the cold air intake which allows more air into the engine which helps to combust a higher percentage of the fuel. This gets more power to the wheels instead of out the tail pip in a big black cloud.
