Nope not gonna bother with aftermarket management and all that. I'll probably get rid of the car before it gets too serious. Was just looking for a bit of fun (some people still don't quite understand what I mean by doing up a car and wanting to get rid is just a bit of fun lol)
Well, I'll just have to play it by ear. Got the pressure set to almost spot on 40 psi, bit lumpy at cold idle again now, but runs fine after about a minute.
Had a look through the Bentley manual for E36's, and it doesn't cover the M43 lump... so that's no good. Had a good read anyway, just to try and get some idea of how these engines work. Still nothing.
Checked on RealOEM, and found what was apparently (according to RealOEM) a crankcase breather hose connected to the inlet manifold - which would give endless problems if not properly re-routed... went and cut the hose only to find still-boiling hot coolant come bursting out of it. A quick trip to Halfrauds and back for an 8mm hoses connector and the appropriate jubilee clips later and it's all fixed again.
Still ain't got a scooby doo where what's leaking or not at full throttle. I have however connected a boost gauge - to the wrong end of the stick so to speak. It's connected to the turbo side of the boost pipes, rather than the manifold, so it doesn't give vacuum readings, only boost (and hopefully accurately). I couldn't be bothered to relocate it to the fanimold after I'd spent half hour just trying to get the vacuum line through the firewall and cable-tied in place.
My question for today is... does anyone know where I might be able to find diagram that covers all the breathers and vent hoses connected to the M43 engine?
