Been having this problem for years and I'm over it.

Have an FJ20 with external oil pump. The pump is mounted slightly higher than the sump and it has a -10 oil feed line to the front cover where the internal pump used to be.

Each start up, it rattles it's head off until oil pressure comes up. 

My solution is to set a start delay in the ecu until it sees oil pressure. Problem with this, it takes ages to start each time as the longer it sits, the more prime it looses.

I looked at an accusump as a solution which would of course work, but are there any other fixes?

I've been looking at small electric oil pumps that i could fill the system with first but nothing seems specific for the problem.

Any suggestions would be great.

Thanks

Pull Belt off and turn pump with a drill, put belt back on and start car 

Bit of a task to do every start up.. lol

Do you have an option to overfill the oil enough to get to the level of the pump (without going above the windage tray), or remake the bracket to lower the pump?

No, pump is too high and lower control arm in the way unfortunately.

I could only imagine using a small transfer pump style thingo and a solenoid valve. Valve closed all the time, open when you run the pump to prime.

Can't imagine it would be fun to fit it all in though.

If the pump is small enough and doesn't even need to do much pressure. Just needs to fill the lines. Finding it hard to locate something to do that job..

Can you put a large enough one way valve in the pump supply to stop drain back without impacting full noise flow?

I've looked into this and the answer I came up with was that the potential risk of restriction and causing engine damage was too much risk.

Bluebirds must get driven much more frequently than Skylines 🤣

Haha. It's already 40yrs old and people look at me weird when it's cranking over for ages before starting..

Given light and clean synthetic engine oil, you could do an experiment with a Facet fuel pump or similar to see if it will move enough to do the job.

I'm currently looking to see if an assembly lube pump hardwired in with work. Can't find the right pump yet..

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
