Guys;
I remember an engine oil company advert from some time ago stating that "90% of engine wear occurs on start-up"...I think that's mostly hokum if the engine was last run yesterday...there's still plenty of oilfilm on everything. But we can agree that it certainly is true if "yesterday" was years ago...
I'm less concerned about pulling the Distributor to turn Oilpump (although I would definately do this also to preoil the Crank and Cam bearings)...for engines which haven't run in a year, I just pull the Spark Plugs so there is no compression and let the Starter do the pre-oiling (Ignition Disabled!)...this will also make it easier on Conn Rod bearings...they wont be working against compression, only resistance of surface rust on cylinder walls, and adding a bit of oil into each cylinder will help that...
What concerns me (a lot more!) is the lack of lubrication on Camshaft and Lifter interface...we all know about soft Cams and rounded off lobes, so lubrication/prelubrication here is of high concern to me! (Cam lobe and Lifter interface is pretty much open to Sump so will have drained completely and be bone dry (and also have surface rust), but still under high preload from Valve Springs...I consider this very BAAAADDD!...opposed to Crankbearings which I'm convinced because they are somewhat enclosed will retain some oilfilm, even over a long storage time).
If I was going to "Overdo it", I'd completely back of the Rockers AND pour some oil down the Pushrods to prelube the Cam/Lifter area...then spin the Engine for a 30 Secs with no Valves and no compression, then reset Valvetrain and spin, then add Spark plugs and spin, then add (fresh of course!) Fuel, set and enable Ignition and Start...that's how I'd "Overdo it" to give an engine the very best new start. Whadoyathink?
Cheers
