Torque question
I have a question about torque. I recently put the oil pressure switch back in and the manual said to tighten it 96 to 144 inch pounds. (8 to 12 ft lbs) But for leak areas I always use teflon pipe wrap (staying away from the first couple of threads in, leaving them bare). I stopped pulling at about 4 ft lbs because it just felt right to me. My question is:
When using pipe wrap it cuts down considerably on the thread friction and allows you to more easily tighten the part. So I'm thinking don't pay much attention to torque values when using pipe wrap or you might strip something ?
Appreciate any info.

Your thinking is right. A torque spec depends on the nature of the threaded connection. dry, coated in oil, etc..... If you use teflon tape, then you must be careful not to torque too tightly which is what you did. If it doesn't leak, then you're golden IMHO.
FWIW, using a torque wrench on non-critical fasteners can cause way more trouble than it is worth. A good feel is often a much better way to go.

I'm certainly no expert but I wouldn't use pipe wrap on the treaded connection you are speaking of. Instead I would use something equalivant to blue locktite, say for instance a hi-temp silcone gasket sealant. I think pipe wrap takes up too much room between the threads and doesn't allow you to thread the pressure sensor as far in as it should be and reach the necessary min torque as specified by the Service manual. Anything with fine threads should be sealed with a viscous sealant imho. Pipe wrap is for course threads as in Water pipe, or fuel gas piping!!
