The rear of my TT has been up on jack stands for about a week, and I'm sure all of the oil has gone to the front of the motor. Is there anyway to crank the motor without starting it? I'd like to build up oil pressure before it fires.

Thanks,
Connor

Pull your fuel pump fuse. C4

but wont it still fire from whatever is in the fuel lines?

what about C1 engine electronics, or C2 ignition?

Not like the old days when you could use a drill to turn oil pump lol a fuse would be best as suggested above.

Yah it will fire. Whenever I pull the fuse for an oil change I always turn the ignition afterward to clear out the fuel lines. It does fire and run for a quick second or two. However I'm not so sure I'd worry if it's only been sitting for a week. My car sometimes sits for much longer than that and I have never heard or felt any alarming low oil sounds or symptoms.

Pull the fuse and turn the ignition prior to draining your oil. It will burn the fuel that is in the rails.. It won't fire when you need to prime the engine.

just start the bloody car, its fine.

Priceless!

What am I missing? I've built dry sump motors for over 45 years (for a living) I also change the oil on the Turbo generally at about 3500 (once a year). What is it about a few revs of a well broken in motor immediately after changing the oil that will hurt anything if the motor fires?

Sorry, I don't get it. It's not like all the residual oil has dried up and the parts are no longer protected. It's not like a few revolutions without oil pressure makes any difference whether the motor fires or does not fire.

If you are firing a motor for the first time after a teardown and want to establish full circulation and pressure before firing, I understand.
But after an oil change, or even after jacking one end or the other? Not saying don't do it, just wondering why?

It's like asking why accusump oil pressure tanks are used on engines.. Most of them are installed on dry sump or remote pump engines. I would'nt sweat a few RPM's of fuel firing, but pulling the pump fuse is a great little trick to reduce engine wear. The majority of engine bearing wear studies point to engine start up as being the culprit for accelerated wear.

Priming these engine on a oil change is like picking the color of your car, or changing the oil yourself. Do what makes you happy.

I start my engine on average once a week, car is stored in brick garage.
Lowest temp would be 50F for a couple of months of the year and use 5w 40 Mobil.
Do you think I would need/benefit to prime it or just normal start ?

Kevin

If the engine sits for months, you can pull the fuse. I wouldn't go remove the fuse with the car sitting for a week or two..
