Part #COMP4-139
Revised 1/21/11
Proper Procedure
As soon as the engine fires, bring the RPM up to 2000 to 2500 during the first 30 minutes of operation. Slower
engine speeds will not supply the camshaft with an adequate amount of oil for the break-in period. The engine
RPM may be varied periodically from 2000 to 2500 to direct oil splash to different areas of the camshaft. After
the 30 minute break-in period, change the oil and filter again to be sure all contaminants and break-in lube are
removed from the engine. The inner valve springs should now be replaced and/or the correct rocker arms
installed.
Helpful Hints and Tools
1. Double check your camshaft and lifter set-up using COMP Cams® Lifter Centerline Tool (0.842"
diameter − Part #5019; 0.875" − Part #5020; 0.904" − Part #5021) prior to the break-in process, and
use an ample amount of the supplied assembly lube on all lobes, distributor gear and the bottom face
of each lifter. For more COMP Cams® Assembly Lube (Part #153) call us at 1-800-999-0853.
2. Nitride your new flat tappet cam to increase the case hardness and lobe surface lubricity; available as
an added service for any COMP Cams® flat tappet camshaft (COMP Cams® Part #1-111-1).
3. Use high-lubricity, high-ZDDP COMP Cams® Break-In Oil (Part #1590 or #1591) to help during the
break-in process and while running, or use COMP Cams® Camshaft Break-In Oil Additive (Part
#159).
