This common-rail combo is listed for the 2007.5–2018 6.7L Cummins. It includes a 161/191 OEM replacement camshaft, heavy-duty pushrods, 103 lb valve springs and tappets, with break-in and oil requirements detailed below.
What’s included:
- 161/191 Camshaft (fits 07.5-2018 Cummins)
- Heavy duty pushrods (OEM power to over 3000 hp)
- 103 Valve Springs
- Tappets
Modification Required:
- There is no modifications required with this “OEM replacement camshaft”
Break in:
To make sure that you have no issues during break-in, follow these few suggestions.
-Disconnect the fuel system and spin the engine with the starter until oil pressure can be read or until oil is coming out of the rocker arms on cylinder#6
-Do not let the starter run for more than 10 seconds at a time
– Once oil pressure has been verified, let the engine start and run until operating temperature is achieved, then shut engine down
-A hot-retorque is very important and will change the valve lash setting, so it is important to set lash last.
-Adjust valves (.010″ intake/.020″ exhaust) then you are cleared to abuse your engine. Enjoy the added airflow
2-3 times a year I get calls from customers that have lash starting to get loose on the last 3 cylinders. This is caused from poor lubrication at the time of initial start-up. In this case the cam literally eats its way through the block away from the force of the tappets. Assembly lube and oil pressure on start-up are a pretty big deal to your cam. Don’t let this happen to you.
Not for sale in the state of CA
Approved oil — required. Use a 15W-40 (or 5W-40 in sub-zero conditions) with adequate zinc, phosphorus, and molybdenum. Thin or low-additive oils don’t provide the shear strength a flat tappet needs. Approved oils:
- Valvoline Full Synthetic 15W-40
- Valvoline Synthetic Blend 15W-40
- Valvoline All-Terrain 15W-40
- Schaeffer’s 15W-40
- Mobil Delvac Extreme 15W-40
- LIQUI MOLY Touring High Tech 15W-40
- Driven Racing Oil 15W-40
- Redline 15W-40
Acceptable:
- Shell Rotella T6 Full Synthetic 15W-40
- Shell Rotella T5 15W-40
Preferred filter: Fleetguard Stratapore LF16035. Running a non-approved oil voids the warranty. All warranty claims must include the failed parts and an oil sample.
