Gasket Set Lower Cummins Engine 6C.83- 6CT 8.3- 6CTA 8.3
Installed in the EGR (Exhaust Gas Recirculation) circuit. It serves to create a seal between the EGR valve and the corresponding manifold/duct, preventing exhaust gas leaks during recirculation. A proper seal allows the EGR system to correctly route a portion of the exhaust gases back into the intake and contributes to the proper functioning of the emissions control system.
It is used on Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC, QSC, ISL 8.9, and QSL 8.9 / 9 engines.
I wouldn’t automatically consider all ISC/ISL/QSC/QSL units to be compatible. To ensure a proper sale, you need to verify the ESN/CPL and EGR configuration, because specifications can vary depending on the model year, emissions certification, and engine build.

The pump is mounted on the engine using a two-hole flange. A push rod driven by the cam profile sets the internal impeller in motion; this alternately draws in and delivers fuel. Its function is to draw diesel fuel from the fuel supply system and deliver it to the injection pump at an appropriate pressure and flow rate.
It is an individual gasket installed between the cylinder head and the exhaust manifold. Its function is to seal high-temperature exhaust gases, preventing leaks between the cylinder head and the multilayer metal exhaust manifold.
Used on Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9 / 9, ISLe, ISL G, and QSL 8.9 / 9 engines.
Before purchasing, I recommend contacting the distributor to verify the product using the Engine Serial Number (ESN) and CPL, especially for the ISL G, because some configurations require the updated gasket.

Gasket Connection Cummins Engine 6CT 8.3-Cummins Engine 6CT 8.3
This kit is designed for the lower part of the engine and includes gaskets, O-rings, seals, and oil seals used during engine overhaul or rebuild. It is used to restore the sealing integrity of the lower engine components, primarily preventing leaks of oil, coolant, and other fluids, as well as ensuring proper sealing of the components during an overhaul.
Motors with verified compatibility: 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSCC 8.3, ISL 8.9, QSL 8.9
Final compatibility must always be verified using the ESN and CPL, because not all configurations within the same engine family necessarily use the same gasket set.
Head Gasket Cummins Engine 6CT 8.3-Cummins Engine 6CT 8.3
This is a set of gaskets and O-rings for the upper part of the engine, used during work on the cylinder head. It is designed to restore the seals after the cylinder head has been removed, preventing leaks. It contains various types of gaskets, O-rings, and sealing washers.
Motors with verified compatibility: 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSCC 8.3, ISL 8.9, ISLe 8.9, QSL 8.9
I always recommend verifying the Engine Serial Number (ESN) and CPL, as well as the ISC/ISL/QSL version. In particular, the included head gasket may have a specific thickness or configuration.

A rocker arm shaft designed to transfer the rocker arm’s motion to the rocker, ensuring proper operation of the engine’s intake and exhaust valves.
Cummins C Series 8.3 L engines, including the 6C, 6CT, 6CTA, and C8.3. Cummins specifically notes that these are primarily intended for use on non-certified C 8.3 L engines; additionally, aftermarket applications include ISC, QSC, ISL, and QSL engines,
Before considering them 100% interchangeable, I still recommend verifying them using the ESN (Engine Serial Number), CPL, and QuickServe, because their application may vary depending on the engine configuration.

It is identified as a Cummins cylinder head for diesel engines. 6 cylinders, 24 valves. It is mounted at the top of the engine block, above the cylinders. It is secured to the engine block using cylinder head bolts, with the cylinder head gasket positioned between the cylinder head and the engine block. It seals the top of the cylinders and forms the upper part of the combustion chambers. Its main functions are to allow air to enter through the intake valves, to expel exhaust gases through the exhaust valves, to house and guide the valves, to support the fuel injectors, and to allow lubricating oil and coolant to flow through dedicated internal passages. Valves and springs included.
It is recommended for use with Cummins ISC 8.3 CM2150, QSC 8.3-500 HO CM850/CM2850, ISL 8.9 CM850, QSL 8.9 CM850/CM2850, QSL 9 M CM2250 L106, and 6C 8.3 series engines.
Always double-check; I wouldn’t assume the number is universally interchangeable on every QSL/ISL without verifying the ESN and CPL.
It is located at the top of the engine, under the valve/rocker cover. It is installed between the rocker/valve cover and the top of the cylinder head, creating the seal needed to prevent oil leaks from the valve train.
Fitted with Cummins 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9, ISL 9, QSL 8.9, and QSL 9 engines.
Before making a purchase, I recommend always verifying the part using the ESN (Engine Serial Number) and, when available, the CPL in the Cummins catalog. Alternatively, you can verify it using the valve cover number, casting/stamped number, exact engine model, machine serial number/VIN, OEM parts catalog, or by comparing dimensions with the original gasket.
The gasket is installed between the valve cover (rocker/valve cover) and the cylinder head. Its function is to seal the top of the cylinder head, preventing oil leaks and the entry of contaminants into the valve train area.
Used on Cummins 6C/L Series, ISC 8.3, QSC 8.3, ISL 8.9, and QSL 8.9/9 engines.
It should not be purchased based solely on the engine model. In particular, for ISL/QSL applications, you must verify the type of valve cover; one source specifies that it is intended for use with 8-bolt valve covers. For definitive confirmation, I recommend verifying at least one of the following: ESN (Engine Serial Number), CPL, the Cummins QuickServe catalog, the valve cover number, the number of bolts, the VIN/vehicle serial number, the parts manual, and a dimensional comparison with the original gasket.
