oil pressure warning light has started to come on - BUT ONLY - when van is slowing down/stationery - at traffic lights - slowing at roundabouts - as soon as the revs start to go up - it dissapears completely -
when it starts up it's sometimes accompanied by a low level 'buzzer of doom' sound -
oil level fine - recently changed (with a good brand of mineral oil) - engine doesn't overheat and drives well - pressure seems to be fine -
i'm guessing it might be the switches /an electrical connection -
i've found the low pressure switch 'screwed on to the side of the crankcase' - with a green wire coming out of it -

but haven't got a clue where the high pressure switch is located -
haynes says - 'mounted on the rear face of the engine below the oil pump' -
errrr.... right... just about know where the engine is! but where's the oil pump!
i've had a root round the bottom of the engine bay - cant seem to locate a similar looking switch or wire -



any ideas?

plus where to get a good replacement switch from? and is it just a case of pulling the wiring off - undoing the old switch and putting a new one in? oil leaks to be expected?

any views or opinions welcome -

the second switch is located below and between the crank pully and the water pump pully. you will have to take off the silencer and a section of tin where to get to it, it is i bit of a fiddle, there should be a wire to it snaking over the top of the engine.

cheers matey -
also found this really useful piece of info that others might benefit from -

i'm assuming that the one i need to replace is likely to be the 'low pressure switch' - easily accessible - located between the l/h side cyylinder push rods - as the light only comes on at idle / very low revs - and goes off straight away as soon as the revs go up?

sleeves rolled up n giving it a bash tommorrow...
