Hi guys

I've just bought a 75 3.0 as a project car to do up as a 'fast street' vehicle. As I go over it with a fine toothed comb, I'll fix things along the way.

First question is about the oil pressure sender. I suspect it's not working properly because it reads very low. I had the same problem in my 155, and replacing the sender cured it.

On the 3.0, where is this sender? And what does it look like? I presume it is different to the oil pressure switch that merely gives a warning light if the pressure is low. Same kinda setup in my 155, where there are 2 separate sensors.

On ebay, I see plenty of oil pressure 'switches', but they look too small a unit to be an actual pressure sender. I could be wrong, but don't want to buy the wrong thing.

Oh, there's this one, it looks to be correct:
BECK/ARNLEY 201-1418 OIL SWITCH WITH GAUGE - eBay (item 150580442412 end time Apr-20-11 06:33:41 PDT)

Please confirm.

TIA

That's it, yes. It's in the rear center of the engine between the heads.

Awesome. Thanks. I'll stick my head around the back to find it!

It's a bugger to get at and requires a modified spanner of some sort and a lot of patience. Even my highly experienced Alfa mechanic doesn't like replacing them. I must try and get a look at the spanner he uses one day.

Cheers. I checked it out today.

I already plan to remove the plenum to clean and spray paint it, so I'll get to it at the same time. Indeed, didn't look like much room to manoevre a spanner.
