Rebuilt 4J - oil pressure for first start up??

[BrokenMu]

For those of you that don't know, I'm in the process of re-installing my rebuilt 4JB1T and I have been informed by the engine rebuilder that I will need to pump at least 3 liters of pressurized oil through the motor before I start it up for the first time.

Does this sound correct? If so, how the heck do I go about doing this?

Cheers for any help provided.

Regards

Never heard that one before but it has merit.
He should of used some sort of prelube on the bearings but the other issue is priming the pump. He might be doing this to cover himself but I would have to ask him how to do it.
Chevy rebuild manuals want you to pack the oil pump with a special grease to prime them.
One option would be remove the glow plugs and fuel cut off wire. Then spin the engine on the starter till pressure comes up. Reassemble and drive

Thanks geeves.

He did say it was to prime the oil pump and that it had to be pressurized into the engine via the oil pressure switch. The only thing I could think of to use was those little oiling cans that have the hose with the threaded nozzle at the end - providing it is the same thread as the pressure switch. pumping 3ltrs in with one could take a while though...

My mechanic that I used to go to for all of my petrol cars said to just put 3ltrs of oil in, let it settle for a few minutes then add the last 2ltrs and crank it over as soon as the last drop is in.

Where would I find the fuel cut off wire?

I've rebuilt plenty of motors and always oiled everything well while assembly, then filled motor with proper amount of oil and spun it over with starter with plugs out and ing wire off untill I got a reading on the oil guage, then your good to go. I'm sure if it was rebuilt professionally that they used a prelube like Geeves said. what they mean by pressurized oil is just that, making sure you have good oil pressure before starting the motor
