Question about oil in a empty engine
 

I just got done replacing all of the seals, o-rings, gaskets, blah blah blah in my engine let were leaking. I put in Carrera tensioners and a new turbo as well. The engine is completely empty of oil right now as I just put it back in the car. My question is how do you prime everything before starting the car? I have no oil in the pump, turbo, any of the new oil lines. I don't want to just start it like that. What do you guys do?

Can you cut off the fuel and spark and crank it till you get oil pressure? When I assemble I always try to prime areas as it goes together.

Yeah, I could do that. Is that going to be fine? How long do you think it should take to build pressure?

I didn't read your post right, I thought you rebuilt your engine, you never cracked it open? that means there is still oil in it, you should have pressure rather quick, I would just give it a few 5 sec cranks and I bet the lite goes out. It would be no different than me pulling mine out of storage after a year I would guess.

No, I never cracked the case. It is drained to the point of no matter which way the engine was in the stand there was no oil coming out.

Just kill your ignition and spin it a wihle on the starter. You can spin it (in 10 second intervals with rests in between for your starter) until the oil pressure light goes out and/or you see your pressure gauge start to twitch. Just did a new engine and only took 20-30 seconds total.

Great. Thanks guys.

Remove spark plugs so the engine can spin faster/starter has less resistance to rotate. Not sure oil pressure threshold will be high enough to register on the gauge, but you could temporarily loosen a convenient pressure line and watch for oil (e.g. oil fed chain tensioner) to confirm.

That's how I do it, as well...

That worked perfect. Thanks a lot everyone.

Will this put fuel into the cylinders?

I pulled the fuel pump relays to prevent that.

With CIS (as in a "stock" 930), the injectors release fuel when the metering plate is depressed. However, the fuel pumps can be rendered inoperable by either disconnecting the wire on the overboost sensor, or pulling the two fuel pump relays closest to the windshield on the luggage compartment panel, or by pulling the overboost relay on the engine compartment fuse panel.

Thanks!!

Sandman, if that is true you are a genius!!! I do know I have shorted the overboost sensor to ground in teh past to make sure that was not the problem, but can I really not even have to pop open the fuse box to crank the motor to build oil pressure?

If all your wiring is still "stock" (not tampered with or "re-wired" by a previous owner), then yes, disconnecting the wire to the overboost sensor will kill the fuel pumps.

Damn the disclaimer. I am not sure how stock all that wiring is since I tried to remove most of the aftermarket stuff they put in there but I certainly did not get it all. Oh well, time to pop the boot and pull the relays.
