CAMSHAFT BREAK-IN and Modern Engine Oil -- CM-108
A few words for the wise, from the wise. Problems with modern engine oil and flat tappet cams are not nearly as dire as some rumors would imply. Linked here is a modern update of camshaft break in instructions from Crane Cams. It contains a few added notes about special oil to be used during the initial 20 to 30 minute break in run. Thereafter it it says, "Refill the crankcase with a premium petroleum-based oil, not a synthetic oil", and that's it. There is no mention of any need to use any special oil or addatives after the initial break-in run. Please read and enjoy.
