If using Common Rail lifted with larger head, make sure it clears the fuel pump lobe #5 on 12V engines. CR blocks should be okay but you should still check. If your gear is not pressed on all the way, the lifters could touch. Extra clearance may be required with aftermarket connecting rods. Drop-in cam is applicable in MOST cases, you MUST check clearances. Especially if a head has been planed, block decked,valve recessions..etc. Always check clearances before starting.

Break-In Procedure:

  • Cam lube on all lobes, lifter faces, and oil pump gears.
  • Oil all bearing journals and lifter barrels.
  • Always turn engine over by hand before starting, check for clearances and proper timing location.
  • Fire up to 1800-2000 RPM for 18-20 minutes.

Zinc Additive:

Most oil companies have taken out a percentage of additives that are meant for anti-scuffing for break-in on flat tappet cams. A zinc additive must be added to your oil before you fire up your engine for the first time.
