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

      Given it is temporary, I bought a  cheapy gauge mount (which has become enflattened) which I will screw into the existing phone mount Also a first for me; given this is a temporary install I could not think of any reason not to use one of those "add a fuse" thingies to source the battery and IGN power. I had always figured they were pretty dodgy but having a good look at them I think they are a valid option for sourcing power from an existing source without cutting

      Finally for now, a bit more work on the transmission temp gauge. I was wondering how Raceworks do a gauge for $100 that autometer want $500 for. No idea about the accuracy of course, but they have cut a few corners that made things hard.  First one I mentioned above, the sender is physically difficult to fit and doesn't work with their own adapters (the extra fittings I used to get the sender into a hose cost more than the whole gauge, lucky I had stuff in the shed) Second, the temp sender wires are way too short. They are shown as 2.7m on the box and I know my routing was long from navigator headlight to driver's firewall back to centre console, but I had to lengthen them by about 2m total - 2 joins in each wire. Also, same with the supplied power loom, they needed about an extra 1m to get the fuse box where I sourced power. Another join in each wire since one end wasn't supplied terminated. I know they could argue that the wires might be long enough depending on situation, but when you consider parts and particularly labour, it would be a very expensive cheap gauge if you can't do the work yourself. And, only a small issue....but it would have been nice if they remembered to tap a tread onto *both* spacers they supplied for the bracket....I haven't had to use the M4 tap often!

      If it does get a turbo it would blow the JCW Mini out of the water considering how "close" some of the tests were. Then again the Mini would probably get one of them Stage 69 tunes.

      Next up, the extinguisher is mounted but really only temporary because I ran into clearance problems (the bracket fit fine....until I put an extinguisher on it). It picks up the seat bolt mounts but has long bolts running through 20mm spacers for now Doing it properly requires a bit of quick welding but I ran out of time, this will do for the practice day

      Family events weekend but a snuck a couple of things in. NSW state champs were down at Wakefield so I got Gordon Leven's to bring some A052s down in the right size for some spare rims I had that "fit" (actually ex-Leaf Nismo.Rays in 18x7.5). Tyres are 235/45/18 so they are narrower than stock (19x8.5s) but I need to keep road tyres on it for daily use for now. In a first, those weird size tyres had been in the yoko warehouse for so long (4.5 years apparently) that they offered 4 for the price of 2....so 4 practice tyres for about $1100. Bit of a bargain for sticker tyres, considering the real purpose of the practice day is mostly to see how the various temps go (and the weather is due to help, forecast 32o). In terms of race wheels, it looks like I should be able to fit 9.5 fronts and 10.5 rears but 18 vs 19 height will be based on what tyres I can get in the right size - good tyres are very limited in available widths in diameters above 17" so some planning is needed. Once I'm sure this car will work I'll order a set of custom BC wheels like I did for the R32, you can get exactly the right width and offset to make the most of the available space in the wheel well (the 32 has 295s all round on 18x10s and they are awesome) Incidentally A052 are asymmetrical but not directional which is good news for rally use if the front and rear wheel sizes are different because I can swap them side to side on the same axle. Directional tyres are a nightmare with staggered size wheels because each tyre is fixed on that corner unless you can get it rotated on the rim (not really practical mid rally in most cases)
