Oil pressure switch / teflon tape in reverse?
HI
I am preparing to replace my leaky oil pressure switch tomorrow night and have some teflon tape to prevent leaking.. Question is, common advice is to put it on the threads so it won't bunch up when the item is tightened, but rather have the tape tighten on the threads..
Can someone give me the quick idea ? I've only used it the normal way, from bottom of the thread to the top..
thx

If you put the teflon tape going against the threads instead of with the threads then when you screw it in, its not going to come off and bunch up, its going to stay where it is and stretch a little. i.e. tape it on counter clockwise if your looking from the back of the sensor, clockwise if your looking into the sensor. Hmm...thats the best way I can explain it.

Yes, Permatex will work fine.
But about Teflon tape. Don't use it on oil pressure senders. What happens is that the first time you install the sender with Teflon tape, the tape is cut by the threads. The next time you remove the sender, little strips of tape are left behind on the threads in the engine. Then when you reinstall the sender, the little pieces of tape are pushed into the oil gallery. They are then pushed by oil pressure to a place with tight clearance and get stuck and can obstruct oil flow at a critical area.
Use Teflon paste instead.
