you might have two springs in your pressure regulating valve on the oil pump.

i've noticed in my oil pump that there are two springs in there one is the main spring which controls the pressure and the other one sits inside it and is alot stiffer and a bit shorter than the main one so when its cold or at high revs the main spring compresses and then hits the second stiff spring making the oil pressure skyrocket.

the gallery restictors will be contributing as well.

Cool then.... I'm good to go. I just put a adjustable valve on my oil inlet hoses to reduce the volume going into the turbos. I unhooked them while at idle and let them flow into a cup to measure the oil volume. It was quite abit still, even though I have the restrictors that come in the center section.

After a few spirited runs, it has taken care of the excessive oil flow through the BB turbos...

Its been a little over a year now and she's still running strong.

I have to admitt a boo-boo I did, causing the oil problem I described in the beginning posts. I was having oil coming out the comp housings, and I discovered that I had hooked up a new oil catch can, but did not vent it.

I ran a -10 line from each valve cover to the can only, and the can was not vented.... Doh

So, once I discovered that little screw up, I opened up the catch can, and added a filtered vent and everything cleared up....

Just wanted to update this thread since I've been absent all this time.

Later - and thanks for the help!

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
