Oil pressure switch how tight?

[Si_P]

I am replacing the oil pressure switch off the oil filter mount. Is there a torque this should be done up to? or is it just v tight??

The engine is a 1.7d

don't do it too tight - I don't know the torque I'm afraid but if you strip the threads in the filter housing then you'll regret it! I would do it up to about 15Nm then keep an eye on it. I know some people also put PTFE tape around the thread (in the direction of doing it up).

I thought that would be the case what with screwing into an aluminium housing. Ta
