How do.
Just a quickie.
Just written this for the blog, thought it maybe useful here?

:ok good that

Anybody got any reccomendations for a budget oil pressue guage and what thread adaptor is needed?

Been meaning to buy one :D

Is that what you were after.

I've never fitted a gauge to a WBX but am wondering this = I know there is not enough space around the high pressure switch to fit a "T" piece and from what I remember, there is very little space around the other one too. Just a thought. How is it done folks? (not that I am going to fit a gauge, just curious).

No mention about the white 015-0.45 bar fitted to Aircooled engines 021919081B.

I can see a blog update coming up ;)

Hey Simon, we know you prefer Diesels to WBX's, but where do air-cooled motors sit in your list ?

Screw an extension pipe into the block, then the T-piece on the end of that. A P-clip or similar around the T-piece, to the tinware at the back of the engine bay.

No, to be fair I missed that, while looking through ETKA I just presumed that with it being white it was a NO switch and obviously Aircooled lumps never ran the buzzer if doom I skipped it.
As it is though there is 0.05bar difference between the blue and the white, hardly worth stocking the white one with such a little difference in pressure.
[nominal pressure listed by most aftermarket people have it as .3 bar, the blue switch is listed at .25 bar.]

We hardly see them here, generally on their last legs, usually been ruined with 009 distributors and sporting knackered carbs with no heaters, they aren't the best.
I owned and ran one for a long time but I would never go back when there are much better options.
We also see very few CS engines now, can't remember the last time I saw a DF...
CT engines, I think we've seen 2 here in 8 years, ditto for the KY, just don't see them.

True the blue switch can used in place of the white switch on air cooled engines. But it needs mentioning as it is also perfectly feasible and not unknown to fit a white Aircooled switch in place of a blue switch on water cooled engines. Which is then when confusion and misdiagnosis can happen.

I was thinking more of a test guage and not a permanent fixture, something like below, so it has a 'standard' 1/8 NPT fitment so I guess you need a an adaptor to the M10x1 hole in the block?

also how would you know your oil pressure was at 80 degrees?

We have an old MOT gas analyser that measures oil temp. With a probe that replaces the dipstick, it also measures engine speed. We are a garage however, that's what we do.
To be fair, if you run the Van at fast idle till the temp gauge needle shows half then you aren't going to be far off.

Ahh yes dipstick of course
I can do a thermocouple on a multimeter I just had a mental block as to which hole to poke it in
:ok
