The bleeder screw is a local high point with low points either side. That's why it is there. If you rely on the coke bottle in teh rad trick, you don't necessarily bleed the bubbles out of the spot where the bleed screw is.

FWIW, when I put the Neo into my car the bleed screw was comprehensively blocked up and need a solid bout of gynecology to open it up.

Hey guys, sorry for another thread revival but i cant seem to find much info about the coolant/vacuum pipe where the coolant bleed screw is located. This was the best info i found so far so thought id ask ☺

I have my engine apart and have been cleaning, prepping spraying etc everything. A mate helped me sand blast alot of different pipes and brackets along the way and i believe there now might be a small amount of sand inside this tube. I just wanted to know how bad this could potentially be and what would be the best way to clear it all out?

Any tips and info about the pipe would be very appreciated. Cheers

Cheers Ben, from what i can tell its just a coolant and vacuum pipe and was just going to blow it out thoroughly with comp air or somthing.

Does anyone know what the valve/rattle is for?

Skinny flat blade screwdriver, poking wire, cursing and swearing. Some tantrum & jumping around too IIRC.

Getting it off is as you say.

I thought I'd chime in. Had the same issue. Going to put a swirl pot but nothing came out of the bleed nipple. It was filled with gunk. I cleaned out but still no luck. I shone a bridght LED torch and it looked super clean.Was scratching my head then it clicked...It must have a port on the side which we cant see.

So, I had some thick wire(welding filler rod). I bent about 2mm off the tip.. shoved it up the hole and twisted it around like i was f**king a whore... I can confirm that there is a hole inside the bleed screw hole, at the bottom. It took about 2-3 mins of poking, and in between spraying brake cleaner to get the crap out.. After i broke through, i cleaned it out as much as poss, and it all works. Water started pouring out when i started the car. 

Hopefully this info will help others, as I couldn't find this level anywhere.

PS - Excuse the mspaint skills. Hopefully it makes sense.

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
