[Healeys] Oil Pressure

[Michael Salter]

I coat the lifters and cam liberally with Crane Cam Lube upon assembly and
I put VR1 no synthetic in the pan by pumping it in through  a "T" on the
the oil pressure line.
When pressure is established I crank the engine for several 20 second
bursts about 5 minutes apart ensuring that oil pressure is well established
each time.
I then start the engine and run it up to 12 - 1500 RPM for about 15 - 20
seconds.
I let everything cool down (5 - 10 minutes) and do the same again 2 or 3
times.
Only after that do I start running the engine up to temperature.
My theory is that it's important to prevent the high spots on the cam and
lifters from getting hot until they have had a chance to "bed in".
It works for me but as they say ... results may vary!!
