Re: [tech] Q's on installation of used cam
Here is a copy of a tech note from DANA/Clevite Engine parts, the reason is
truly for proper oiling on intitial start up.
Camshaft Break-In Procedures
Coat the camshaft lobes & distributor gear with an EP lubrication such as
CL400 "Cam Guard" or a moly-paste.
Apply the EP lubricant only to the lifter contact faces - not the bores.
Prime the lube system using new oil and filter.
Use only oils that meet or exceed the latest API ratings.
Do not use non-detergent oils, they do not have the anti-scuff additives
found in modern detergent oils.
Start the engine and increase the RPM's to 1500-2000. Operate the engine for
15-20 minutes at this speed. The higher speeds increase splash lubrication
and decrease nose loading.
Avoid excessive cranking, no start donations and fuel/ignition adjustments.
The break-in procedure must commence as soon as the engine has oil pressure.
If the engine fails to start within 15-30 seconds, it is recommended to
re-apply the EP lubricant to the lobes.
If possible, following break-in, the idle should be adjusted to high
specifications.
