Re: Oil Prime an LS engine
The instructions with my crate engine said to disconnect the power to the ecu (disconnecting only the ignition or injectors is not recommended), hook up an oil pressure gauge, then crank the engine using the starter for 10 seconds. Check for oil pressure. If pressure, you're done; if no pressure wait 30 seconds and then crank the engine using the starter for 10 seconds. Repeat the process until the gauge indicates oil pressure.
Once you've got pressure, reconnect the ecu, fire the engine and, if there are no unusual noises, let it run at about 1,000 rpm until it reaches normal operating temperature. You're done.
