So I just did a complete rebuild and I just primed the oil pump today using the compressed air into the dipstick method and I got 3 - 4 bar of pressure and 3 bar of pressure without the compressed air. I put 6 quarts of oil in and it filled up to the top line of the dipstick, but after priming I don't see any oil on the dipstick. How much oil should a completely dry car take?

Everything was void of oil including the oil cooler and lines. Zero oil in the car other than the oil used to put the pistons in.

I believe it is 7L which is about 7.5 qts.

Unplug the wire between coil and distributor and crank it over for a few seconds a few times... This builds oil pressure throughout the engine pretty quickly. Re connect the wire and start up...

Using 3-4 bars of compressed air in the crankcase is a great way to blow seals out and make leaks. Just because the oil pressure is 3-5 bars doesnt mean the oil pan gasket and cam tower seals see 3-5 bars.

Like already said, I usually prime the oil pump during the rebuild, crank it with the coil disconnected, and fire it up.

I only had about 10 psi air pressure in the crankcase. So i figured the oil pump produced 3.5 out of the 4 bars of pressure I saw. I was pretty concerned about over pressurizing the crankcase.
