<VV> Pre Oiling

[aeroned at aol.com]

Ah, yet another reason to have an electric fuel pump...
 
My electric fuel pump has a oil pressure cut out. So, after the car sits for a while (or the carbs are otherwise drain of fuel) the engine needs to crank for a while to build oil pressure. Once that happens the fuel will be delivered to the carbs and then the engine will start. Typically, this all take about 10-15 seconds with only the first 3-5 seconds with the OP light on.

 I have pre-oiled a few engines after major repairs or after sitting for long 
periods. It occurred to me that my Vair or my Manx (Vair engined) would sit for 
periods of time or at least most of the winters here. I am sure others are of 
similar thought. It is not that difficult to pop out the dist. and turn oil pump 
on a Vair but it takes time and then you might move something and have to 
readjust everything. Now I have heard all my gearhead days that most of the 
worst wear comes from those few seconds at startup while the bearings are 
screaming for the oil to get there.

  Smitty Says:  Keith I understand where you are coming from.  I too hate to 
start an engine up that has sat for a week or so (or more).  Commonly expressed 
philosophy on VV is to run the pump.  I have a problem with that.  I have done 
so with the block cover off and not all that much is going on there.  For sure 
the cyl walls are not profiting from it.  So I prefer cranking the engine a 
dozen times or so with the coil wire pulled out.  Well within the manufacturers 
limits set on starter operation.  Red light goes out.  Crank throws throw oil 
into the cylinders.  And this is low stress on the bearings.  No combustion 
loads.  No muss, no fuss.
  So I must say this.  Difference of opinion now, Not Flame.  I consider what 
you are talking about to be big time overkill for a minor problem.  Especially 
with a stock Corvair.
