Removing the intake looks ******* the 750il m70 but its not. I took mine off and painted it glossy black with rustoelum. You will need to disconnect and remove your fuel injectors and wire harness. Then with a flat head lososen and remove both of your air filter housings then use a 10mm socket remove your throttles. Dont forget to disconnect the sensors in back of the intakes aswell. Use a 10 remove the intake bolts. The bottom bolts are tricky and hard to see you will need to remove the injector silencers which are the two small walls made of fiber and foil. They are located right between the intake and valve covers. A few screws at the top of the intake hold them in and can easily be removed. After that you will needa long extension to get to the bottom row of 10mm bolts. Use the openings you made by removing the silencers to get easy access to the bottom row. The bolts will fall after you unscrew them so i use a piecec of paper and jam it into my socket so the bolt eont come out. After you remove the bolts you can pull both intakes up at one time. Hoped this helped good luck

The M70 has two fuel pumps; one for each cylinder bank. One of mine died. I was able to access the fuel lines at the drivers side (US) rear of the engine. I spliced in a 10mm "Y" connector to the good pump and tied the two fuel rails together temporarily. Runs like a champ!

Starter needs to be replaced. Need instruction procedure for a do it yourselfer.


Hi, I have pasted the procedure from autozone.com below. Because this requires removal of the intake manifold, please be as sure as possible that your starter needs replacement. If you have any doubt, please let me know what your symptoms are and what troubleshooting you have done that led you to believe your starter is bad. Also, if you have any questions about the procedure below, please let me know. Thanks for using FixYa.

  • Intake manifold heat shield
  • Sight shield
  • Coil module connectors from the coil modules located on the valve covers
  • Positive Crankcase Ventilation (PCV) hose and valve from the valve cover
  • Fuel regulator vacuum tube

    What are the torque measurements for the rocker arms and intake manafold?


    2.2L Engine & 2.4L Engines
    These engines are not equipped with rocker arms. The camshafts directly actuate the valves.

    3.1L Engine & 3.4L Engines
    When install or connect the check the following:
    - Pushrods and the rocker arms. Torque the bolts to 24 ft. lbs. (32 Nm). - Rocker arm cover using a new gasket. Torque the rocker cover bolts to 89 inch lbs. (10 Nm).
    - Heater bypass pipe. Torque the screw at the water pump to 106 inch lbs. (12 Nm), the bolt at the cylinder head corner to 18 ft. lbs. (25 Nm) and the nut to 18 ft. lbs. (25 Nm).


    About the INTAKE MANIFOLD...
    -
    Intake manifold nuts and bolts and tighten to 89 inch lbs. (10 Nm)
    - Pushrods and rocker arms. Torque the bolts to 89 inch lbs. (10 Nm) plus an additional 30 degree turn. - Lower intake manifold. Apply sealant to the threads of the bolts and torque the bolts to 115 inch lbs. (13 Nm).
