Type 1 and type 4 motors used a tapered thread for the oil pressure switches. The water boxer does not. The thread is straight and the sealing washer on the correct switch actually makes the seal.

Subject: Torque spec that requires calibrated fingers

tencentlife's adapter kit for connecting a adapter which allows a fellow to mount a oil pressure gauge sender alongside the stock oil pressure warning light sender has this to say about torquing:

"Torque recommendations are meant as relative guides, it will not generally possible to actually use a torque wrench on the fittings in this installation."

"...Tighten the fitting carefully, it has a taper thread so it will seal into the case hole with moderate torque, generally less than 8-10ft.lb."

and

"The compression fittings should attain a good seal with only 10-12ft.lb. of torque, so don't overdo it."

I'm assuming that some of yinz have fingers calibrated after many years of experience. Is there any wisdom that can be shared here?
