  1. I had a similar problem with my old 323. After 300000+kms, wear in the throttle body shaft/bushes had caused an air leak.

    Also, does the rod on the start assist diaphram retract once the engine is running?? It should be pulled out of the way by high manifold vacuum, but if it is leaking or its vacuum hose is leaking or disconnected it will keep the throttle plate from closing properly.


  2. The angle of the spring, that is to say the spacing between the coils makes a huge difference to the spring rate, you will note how progressive rate springs are wound with varying distances between the coils. The more tightly spaced part of the coil compresses more readily than the more open part of the coil. Many lowered springs are made with a section of very closely wound coils that compress completely with only the static load of the car placed apon them, they are only there to provide adequate free height to the spring so that it remains captive during suspension extension.

    Once I had a set of lowered "King" springs in a wreck that were taller (free height, that is) than the factory springs, so tall in fact that I had to resort to using spring compressors to get them out, unlike the factory springs that could be removed without compressing


  3. Even if you manage to restore the temper in the spring steel, the suspension will have effectively been softened by virtue of the geometric change in the spring. If you can visualise the coils in the spring will be lying more horizontally than they were when the spring was at it's stock length so the weight of the car will have an easier time squashing the spring


  4. I pulled my wrecked Auto transmission out of my 89 E30 318i last night and there was a plug attached to the back of the geabox assuming this is an electronic speedo running from the box?

    I believe the plug you are refering to is the connection from the speedo that signals the transmission to lock the torque converter at 85k's.

    The early transmissions don't have the locking torque converter


  5. Also, the M52 is far more "bolt in" than the M30 which requires custom mounts, maybe custom driveshaft as well. Theres a member in chch who has some of the bits needed for the OBD1 conversion and maybe oilpan if that hasn't sold.

    Actually the M30 doesn't require any fabrication at all. All the parts to fit an M30 can be bought "off the shelf" as it were, it's the high price of the new parts that means most people doing the conversion make there own parts

  6. It could be a bad air flow sensor or at least a bad connection to it. I don't know if the E39 uses this particular protocol but some EFI systems allow the fuel pump to run while the starter is cranking them once the engine has started the ECU looks for a signal from the airflow meter. If after 3 seconds it doesn't get a good signal from the air flow sensor it shuts the fuel pump down again.


  7. I have a 89 318 coupe that has been rolled, I only bought it for the trans so everything else is for sale. It has power steering, disk brake rear, tail lights, episoidal head lights (not simlies sorry) external fuel pump, M40 (240000km) Open to offers .


  8. Difference is the disc/drum t/a's

    The disc'd t/a's are offset for a 8 bolt diff and the drum brake ones are offset for a 6 bolt.

    Are you sure about that?? As there are rear disc cars that have small case diffs, ie. higher spec 316/318 yet their arms interchange with a 325 which all have medium case diffs
