After run Oil

[EHaury at aol.com]

Right on Dean, the pressure on cam lobes and followers is the highest in an 
engine. It only takes a minute or so without lube to waste the surface. 

The EP (extreme pressure) material of choice in automotive lubes, including 
the synthetics, is zinc-dithiophosphate. This stuff protects the cam / 
followers and is depleted as it works, a good reason to change oil. As with moly 
compounds, it leaves ash as it goes through the combustion chamber, not good for 
glow plugs. The good news is that the pressures are low enough in our model 
engines to negate the need for EP agents. (But not oil!)

I prefer Klotz TechniPlate for assembly and new engine pre-lube. Definitely 
remove the cam cover and fill 'er up. The DZ has oil holes in the followers 
that help maintain sufficient lube to the cam in normal use. The last batches of 
DZ's have been pre-lubed in the crankcase, but I've not found oil in the cam 
and rocker areas. Certainly a pre-lube is a good way to protect one's 
investment.
