Hi all,
Does anyone know the how tight the 400-4 oil pressure switch into the oil pump should be? I have a slight leak from it (my only leak after the rebuild which is a bit of a relief!). I gather the thread is tapered - the top part of the thread is pretty corroded, indeed the switch itself looks a bit sorry for itself so as a precaution I'm replacing it - but I cant find any mention of torque settings in manuals (so I want to stop it leaking, but not strip a thread, and I don't want to use any PTFE tape or anything nasty like that to get a good seal).
Thanks.
