persistent minor oil leak

[chris.richard]

Tracked it down to the oil pressure warning switch. Hasn't stopped with tightening and inserting a copper washer. Seems to be leaking from the switch itself - is this possible? :confused:

More than likely! I've had more than one switch failure on various cars - usualy starts with a slight oil leak before it bursts open and dumps the sumpful on the motorway! (Both switches and pressure sensors.)

:eek:

800 miles and it's bust already! :mad:

That doesn't sound very good Chris. Mine always died after a significant mileage. Did it get a knock while fitting the engine or get overtightened perhaps? What switch are you using anyway? I thought most AR V6s only fitted that notoriously unreliable pressure sensor on the front cylinder head.

I put an aftermarket one from Demon Thieves in an unused tapping in the oil foilter housing.

That's probably the same tapping I used for my oil temperature sensor. I think it's some strange tapered thread as I ended up using some sealing compound to get it oil-tight.
