Hi Mike,
Sorry to hear of the leak - always frustrating. Here are my thoughts:
- Check to be sure there isn't a crack or something else that is causing
the leak. Oil can move about in weird ways sometimes and it can be very
difficult to find the true source, especially with clean fresh oil.
- make sure the mating surfaces (both on the block and on the switch)
look good. If suspect, clean them up a bit.
- as for torque, since we are dealing with a 12 mm x 1.5 mm steel switch
screwing into an aluminum block, I would do it up to a MAX of about 29
foot pounds. At least, that is the best I can extract from the torque
specs I have on my website??? Since this is a sensitive area, I'd start
off low and go up in small increments. As always (and I'm sure you know
this) be sure to inspect the threads in the block and be super-careful
not to strip them out.

Hi, all. I am frustrated by an oil leak at my oil pressure sensor. I had the sensor out, and when I put it back in using the same crush washer it started to leak. I put some thread tape on it but the leak persisted, so I bought a nice copper BMW crush washer from Spare Parts, but it still leaked! I was surprised. I thought perhaps the oil was leaking THROUGH the sensor, so I bought a new sensor and aluminum crush washer from MG Cycle. I installed the new one with thread tape as well as the crush washer. It didn't leak for about 25 miles, but now is leaking worse then ever. I don't know what torque the sensor is supposed to be tightened to, but I feel that if I make it any tighter then I currently have it I will strip out the hole. This is such a simple thing: why am I having so much trouble? -Mike (69 ambo, 77 vert) M.Jones, associate editor, Journal for the Study of Religions and Ideologies (http://hiphi.ubbcluj.ro/JSRI/) "The heart has its reasons which reason does not know." -Blaise Pascal "With man, instinct and reason avoid each other with adversity, yet, by repudiating each other they lure each other to reach mutual correction." -Lucian Blaga __________________________________ Do you Yahoo!?
