oil pressure sensor, club shop

Post by denbute » Thu Jul 08, 2010 1:07 pm

Hi,

I bought an oil pressure switch from the club shop last week, got it in the mail today, all fine up to there.
Wanted to fit in the 1210 but it wouldn't screw in. The old one can be screwed in by hand until the end, the new one goes in about 1 turn and than stops. Am I doing something wrong here? Has anyone had problems fitting these switches?

Jonathan. I can't comment on the Shop ones but look at the thread, it should be vey fine and the end slightly tapered to fit most engines as some had larger threaded holes in the block than others. What I'm saying is, a new oil pressure sensor should be a white(ish) or black plastic cone with a male spade connetion on the top and the threaded part of the body should have a tapered thread that is very fine, these are £3.83 + vat.

and I don't think it is tapered, not measured it though.

I just screwed it in using a spanner, could get to the end of the thread.
I think this one has to seal because the diameter gets to big to screw in versus the old one which had a copper washer between the block and the sensor. Wondering if I should have used a little threadlock or similar on it? Hope it doesn't leak this way.

I would have put a bit of PTFE on it.

Jonathan,

as Jim has said I think the replacement ones have a very slightly different thread on them - I had to do the same and use a spanner to get it in - I`m allways a bit wary of this - re taking off the threads. Should be ok, I did what Scooby said and used a bit of PTFE tape and its never leaked.

Cheers

Andy

I have to say I was thinking of fitting an oil pressure guage to my 1390 when I had the engine rebuilt and planned to fit a "T" piece where the oil pressure switch goes. Bought quite a few adapters in various threads which were supposed to be the correct one, but they never seemed to fit correctly so I gave up - one of those things I meant to sort out one day!

If any old timers know the correct hole size and TPI I'd love to know.

Aren't the tapered ones BSPT (the "T" meaning tapered)? I seem to think many old BL cars etc were 1/8" NPT - but it's many years since I put oil pressure gauges in cars (and I suspect VW's are metric)!
