Engine priming

Another maybe stupid question.

I drive my olds only with nice wether, mostly in the spring and summer.

I had to prime my new engine before i started it.
After it sit the whole winter nicely in it's garage, do i need to prime it again?

And if so, i read somewhere that i could prime with vaccuum sorce.
Could i make say something like a bleeder onto the oilpressure tube? to prime it when i gonna take the olds next spring?

I've never primed an engine unless I rebuilt it and was initially starting it. I have taken the plugs out and squirted oil in the cylinders when I hadn't started an engine in afew years and was ready to crank it up. I see no need in priming an engine just due to it sitting through the cold weather.
If you feel better, pull the distributor and spin the pump until the oil comes up through the push rods, but I don't think it's necessary.

Are you talking about priming the fuel system or the oil pump? After sitting for a long period of time, the fuel in the carb evaporates and you either need to crank for a long period of time to refill the carb or you need to prime the carb manually. I usually just crank the engine.

If you're talking about the oil pump, it's good practice but a lot of work to pull the distributor and prime the pump. Frankly I also only do it for new builds or if the engine has sat for a very long time, like several years. If you're worried about it, a compromise is to pull the plugs and crank the starter until there's oil pressure. This avoids putting heavy stresses on the bearings without full oil pressure.

Ok thanks,

I ment the oilpressure
than removing the plugwires is the easy way to start it.

If it's a carbureted car, there are two ways to start it after a long nap:
  1. Pour a half a cup of gas down the carb, screw on the air cleaner (fire bad), and let 'er rip.
  2. Get the battery all charged up, and start crankin'.
    Crank for 20-30 seconds at a time, allowing time in between for the starter to cool. You will slowly fill the float bowl, and the car will start in 2-3 minutes.

If you do it the first way, you MAY start with inadequate oil in the bearings.

If you do it the second way, you will start with full oil pressure (just watch the oil pressure gauge as you crank - you'll have 30-40 pounds after the second or third round of cranking).
