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.

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.

      The BES920 is like the Toyota Camrys of coffee machines. E61 group head is cool, however the time requirements for home use makes it less desirable. The Toyota Camry coffee machine runs twin boilers and also PID temp control, some say it produces coffees as good as an E61 group head machine.

      And yes with a full tank it will hit limiter free revving or driving 6B6CDF6E-4094-426D-A9CB-6C553475FE36.mp4

      One way of putting the fuel surge idea to rest, is that even when in neutral/clutch in or free revving it still has the same issue, it can’t even get to limiter (7800) so to me that says it can’t be g force, I’m not trying to argue I just want to find the f&$king issue 😡
