| − | * Failure to remove all [[rust]]-preventative from cam and lifters with solvent once you get them home.
| + | '''See:''' [[Camshaft install tips and tricks]] |
| − | * Failure to wash the cam and lifters with hot soapy water to remove the remainder of rust-preventative not removed with solvent.
| + | |
| − | * Failure to properly massage an extreme pressure lubricant such as Molybdenum Disulfide into the pores of the metal on all lobes and lifter faces.
| + | |
| − | * Failure to use an extreme pressure lubricant additive to the engine oil for camshaft break-in.
| + | |
| − | * Failure to use the proper valve springs for cam break-in. You can't use the 350 lb over-the-nose springs that you'll eventually use in the motor and expect the cam to live.

| − | * Failure to check for valve spring coil bind.
| + | |
| − | * Failure to check for retainer to valve guide clearance.
| + | |
| − | * Failure to check for binding at the rocker/stud interface.
| + | |
| − | * Failure to check for piston/valve clearance.
| + | |
| − | * Failure to run the motor at high rpms (2500 or higher, alternating 1000 rpm's up and/or down) for the first 35-40 minutes of its life. NO IDLING. NO IDLING. NO IDLING.

| − | * Failure to clearance lifters in their bores so that they spin freely.
| + | |
| − | * Failure to initially adjust the valves properly.
| + | |
| − | * Failure to inspect the distributor drive gear for wear. Too much wear can allow the cam to walk in its cam bore and contact an adjacent lifter.
