To pressurize the oil after engine assembly I have a dummy oil pump drive
which I rotate with a drill.
When the oil pressure gauge shows 50 PSI then everything in my opinion is
ready to fire up.

Betreff: [Fot] Pressurizing the oilins system
Using a tank to fill the oil passages before starting a fresh engine is
always a good thing. What we do is, 1. During assembly of the engine, as
each rod is installed, the rod with its bearing half is pulled up against
the crank, then using a pump oil can with an engine assembly mixture of 40
or 50 sae racing oil and Molybdenum di Sulfide oil additive (like Mr. Moly)
we pump the oil passages in the crankshaft full of oil, then install the
bearing cap and torque into place. Fill the oil filter canister or oil
filter with oil before installing it on the engine. leave the spark plugs
out. Fill the engine sump to the full mark, then crank the engine until you
see 40 or 50 psi of oil pressure on the gauge. In our experience, this
should take about one or two minutes of cranking. You will hear the engine
slow down slightly when all of the passageways fill and oil pressure is
generated on the gauge. Then install the spark plugs, make sure the valves
are properly adjusted and the timing is set correctly. If everything is
right, with fuel and spark, the engine should fire right up. Immediately
bring the idle up the 2,000 to 2,200 rpm and keep it there for 15 to 20
minutes. DO NOT REV OR "BLIP" THE ENGINE UP ABOVE 2,500 RPM DURING THIS
INITIAL CAM BREAK IN PERIOD. raising the surface speed of the lifters on the
cam during this initial break in period can cause terminal damage to the cam
and lifters.
Using this procedure, we have never had any oil
starvation damage to any engines we have ever done. Cranking the engine over
to get oil pressure, with the spark plugs removed, and the oil passages of
the crankshaft previously filled with oil puts no stress on any of the
bearings. There is heavy rubbing of the lifters on the cam and the rocker
assembly (which should also have been pumped full of oil during engine
assembly) and the valve stem tips to the rocker arms. But that is what
assembly lube paste is for..We use Moly (grey colored) assembly lube paste.
Redline also makes a good assembly lube paste. As far as I am concerned,
this is only for steel or iron to steel or iron surfaces, never to be used
where there are "bearings" involved.
