When you start a car, it's got no oil pressure for a few seconds, and all the oil has had time to drain away from bearings etc. That's got to be worse than running an engine
with oil pressure when the pressure is all of a sudden gone for a few seconds. At least the oil film is still there.
I'll agree with you on that one.
When I start my engines, I first crank while pulling out on the shutoff, until low pressure alarm
cuts off. If it has been more than a few days since the engine
has last run, I'll do this with the decompression levers thrown. Then put things back in order, and start engine. Surely this is better for the engine. The engine is being rotated just the same, but the forces from combustion aren't there, nor from compression
, if the levers have been thrown.
This isn't the first i've heard about removing the oil this way, and I'm sure it can be done safely if you are careful, but I'm not ready to do away with pumping out the oil by hand. Not much margin for error.
Imagine mentioned earlier about the Jabsco
hand pump. That's what I use, with a 2 inch long discharge tube stuck into the mouth of a 1 gallon oil jug. I can hold the pump and the handle of the jug together in one hand.
But after 5 years I wanted to replace the pump. Unfortunately, what they make today is not as good as my old one. The pump head
(the intake end)is made of red plastic/rubber whereas the old one was black. The red seems to be effected by oil--in short order. I think I could use it once before it went bad. I'm still using my old one, and am on the lookout for a new system.
