Installation Highlights
With the fuel system disconnected, spin the engine on the starter — never more than 10 seconds at a time — until oil pressure reads or oil is coming out of the rocker arms on cylinder #6. Then start it, run to operating temperature and shut down. The hot re-torque is very important and changes lash, so set valves last at .010″ intake / .020″ exhaust. Poor lubrication at initial start-up is what causes loose lash on the last 3 cylinders; assembly lube and oil pressure on start-up are a big deal.

Notes
- Approved oil required: 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.
