Hi, I bought a replacement oil pressure transmitter for my V8 as the original sender only works when it feels like it, which isn't very often. Anyhoo, I got one from Wins but when fitted, the hex head catches the bottom rear edge of the timing cover? before it seats on the washer. I've had to put the original sender back in. The upside is, while it was out, I cleaned it thoroughly & polished up the spade connectors and it seems more willing to work. Anyone else had this problem fitting a new sender? It was an absolute mare of a place to get to even with the alternator & bracket removed, and utilising the 18mm spanner chopped in half. One thing I've just thought of, though, is there any problem swapping the positions of the oil pressure & oil warning light sensors over? Are the threads the same? I've also heard bad things about the later (black plastic) pressure senders having a tendency to leak after a short time. I'd quite like to get the pressure gauge working correctly.
