328i 325i e36 BMW Camshaft position sensor replacement inline six
Camshaft position sensor replacement. It controls the vanos solenoid. When
this part fails you will feel jumping in your pickup. This part is fairly
simple to replace. You will need to remove the Vanos solenoid; A large
wrench or channel locks should do the trick. Unplug it, remove it along
with the pcv hose. Then remove the oil fiter cap and oil hose bolt. Be
careful not to lose the washer. Then remove the screw holding in the
camshaft position sensor. I used a t30 socket. But it was fastened with an
Allen screw 5mm. The plug for the sensor is in the under the middle of the
manifold hanging there loosely by where the pcv valve assembly is. To
assemble reverse what you did. Should take about 20 minutes to an hour
depending on your experience.
If this part was faulty you will feel an immediate difference in pick up.
Especially on the low end torque. I no longer need to dump my clutch to do
massive burn outs. Thats it the difference i felt.
All the work done on my car cost me very little. But the result is better
than some who have spent thousands to get half what I have making my own
For instance the motor mounts are to soft to do anything crazy, so I used a
deep well socket and some sway bar bushings and a long nut and bolt with
washers to replace the soft mounts after I had broken some expensive
mounts. I decide metal it the only thing that can handle the torque.
Vibration and noise has increased as a side effect of this. I probably will
never do a vid on this.
