Priming Oil System Rb30/rb26

Please can I have some help here guy's. I finally got my engine turning over to try and prime up the oil system. No oil seems to be getting through the system. It got assembled some time ago and I have to say I don't think I put any oil in the pump when I put it on? Also I am running an oil cooler and currently dry oil filter. The latter I can resolve easily enough. But having read a post somewhere I recall a dry pump might not seal and draw properly? Can someone tell me how I can get around this with my oil cooler setup to try and get some oil back to the pump and get it priming. So far I cracked off one of the pipes and turning it over for a minute or so to see if all would come through but nothing. Also I will pull the plugs back out so it can turn over quicker!

Thank you

Lee

Plugs shouldnt be in if your trying to prime. The load on the bearings from compression can be enough to 'wipe' them. You can put oil into the outlet to oil cooler/filter and turn the motor backwards to let it run down and then turn it clockwise and try to prime again.

You should put a smear of assembly lube over the gears to help create a seal when you inspect it and chuck it on.

Thanks for the reply..

This was my plan. I will pull off the oil filter so I know which pipe to use and then pressure some oil back down it and turn the engine backwards a turn or two as you say. I gather there are no worries turning the engine backwards. Like cambelt riding off or something daft. I can't see it as the tensior is locked in place.

Thank you

would the bearings also be smeared with assembly lube to avoid wiping the bearings? is that common practice or am i wrong? nfi :D

The bearings should have assembly lube on them anyway. Only other way is to use oil, but thats an old practice. Fairly certain everyone uses the lube these days. But yeh thats right.

The lube on the gears just helps create suction and protect from dry wear until the oil starts going through it all.

you can take the outlet line off the block (that goes to cooler or remote filter mount) and fill it with oil, then wind the engine over backwards by hands and keep topping it up as the level drops, put about 200-500ml back down the line then reassemble. Crank engine without plugs and oil pressure should jump up quickly.

make sure you fill your oil cooler and oil filter too.

Primed and ready!

Injected some oil down the cooler line back to the pump and turned then engine backwards a bit then popped out the plugs and spun it over.. Light went off after about minute or so! What a relief!

Cheers

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
