Oil Pressure Sensor Torque Spec too high? M44 fellas chime in

[e36Ballen]

Tried searching but I couldn't find a thread for M42/M44 about anyone trying a lower torque value for the oil pressure sensor.

So here are the torque specs:

For M42's it says 40nm which is 29.5 ft-lbs

For M43 it's only 20nm which is 14.75 ft-lbs which is fine.

Mine is an M44 1.9 (Z3) so I'm guessing it's similar to the M42 spec.

It's this oil pressure sensor: - https://www.fcpeuro.com/products/bmw...ch-12611710509

The dual temperature switch by the block is about 13-14nm which is 9.75-10ft-lbs which is fine.

But damn, if I use 40nm/29.5 ft-lbs on this short oil ps, that's scary. Anyone tightened it just about 20nm/14.75ft-lbs? Or hand tight then how much turn?

The M44 oil pressure switch to oil filter housing is 27Nm ( 20 ft-lbs)

As per Bentleys Z3 Service Manual.

If you want the full list of torque settings for the Z3 ( all info taken from the Bentleys manual) send me a PM including an email address, and I will send you a copy of the excel spreadsheet that I compiled.
