Oil priming before each start up

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.

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..

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
