Massnz 2 Report post Posted May 24, 2014 Hey Guys Just a quick question on the Idle Control Valve for an M52b28. I have mine out at the moment and when I shake it, the actuator has a lot of play. Is this normal? A small amount of shaking can cause the actuator to click back and forth from completely open to closed. Quote Share this post Link to post Share on other sites

Massnz 2 Report post Posted May 24, 2014 Sweet thanks for clearing that up Brent. I had cleaned it a while back with some TB cleaner, however i am just troubleshooting some idle issues. E36 328i Auto Symptom 1 : Car idles fine cold, and idles fine when I stop at the lights. But after approx 30 seconds the idle starts getting worse. Giving it a small amount of throttle and holding it there fixes it up (left foot brake, right foot accelerator). Symptom 2 : Drive the car, park it up and leave it running in Neutral/Park for 30 seconds or more. When I change into Drive/Reverse, the revs start fluctuating towards a stall (drop from 500 to ~100 then back up to 500). Does this 3 - 4 times before coming right. I do have a tiny coolant leak in the engine bay which results in the bay gradually filling with a coolant mist (can be seen at night time with headlights on and bonnet open), so I am thinking maybe the mist is getting pulled up the intake and screwing with things. This could explain why the problem isn't present when i first pull to a stop, air flow from driving. I have just spent the afternoon replacing the tstat + housing, upper and lower hoses, waterpump, expansion bottle + new brass bleeder screw so we will see if that solves it, but i guess its a case of going over the basics - MAF, TPS, Fuel Filter etc but any advice would be appreciated.

twisted 45 Report post Posted May 24, 2014 Sorry for the hijack, but Where did you get the brass bleeder screws from? I resorted to two oil feed banjo bolts from a Subaru vf18 turbo. Perfect size and work much like a bleeder screw. However would like to replace with brass screws. Quote Share this post Link to post Share on other sites
Massnz 2 Report post Posted May 24, 2014 Pelican Parts. I was ordering a whole heap of other parts so i included that in my purchase because the freight from USA is a killer. Just added one to my cart, its $8 USD + $45.75 freight to NZ. I usually buy all my parts out of Pelican Parts, but I have purchased some parts locally out of either Milland in Dunedin http://www.milland.co.nz/, or Partsplus out of Wellington http://www.partsplus.co.nz/. I have found both local suppliers are very reliable and knowledgeable. Quote Share this post Link to post Share on other sites
Massnz 2 Report post Posted May 24, 2014 Just noticed you have an E39 though, I have an E36 so I only have the one bleeder screw next to my expansion bottle. You probably have a couple of bleeder screws, and im not sure if the one i mentioned is compatible. Quote Share this post Link to post Share on other sites
