M30 Engine Overhauled

[CLI4D]

Hello, Guys.

I just wanna ask, I bought an overhauled M30 735i engine to be put in my E30 body,No Oil yet, What Oil should I use? And how long is the oil pump going to take to Lubricate? Should I just turn the engine by hand first or Starter Crank? Worried I don't want to Damage the main Bearings as someone told me. thnx in advance.

synthetic oil would still be the best bet.

there's a good amount of oil that is applied to the bearing/s on assembly so for the frst few 2nd that u wait for the oil pump to prime, there should be enough lubrication in there.

If you are "that" worried. u can disconnect the coil first, and let the engine turn over a few times by way of the starter motor to properly prime the oil pump; and then reconnect and start.

You can also watch the oil pressure warning light on start up. If it's slow, shut off and restart. Pressure should come right up and turn the light off.

thnx for your advise.

And, I'm also not sure about my Idle Cntrl Valve, When I switch ignition key to ON possion, not a Crank. I hear a buzzing sound on the ICV, I know the Buzz is normal but what posission should the valve be in ON posision, Close or Open?

I've disconnected my ICV from the Boot Pipe, then inserted my little trusty finger in one of the ICV holes and switched my Ignition key to ON, I can feel the ICV closing as it buzzes, n when I switch key to OFF posision, it doesn't return to open possion is this normal?

I have not started the car yet, I'm still sorting the wiring, it's E30 M30 swap.
