oil pressure light

[alchim]

hi oil pressure light flickers slightly on tickover, but when your raise rpm slightly above tickover it goes out,any ideas anybody cheers in advance

Yours is a pre-serp I assume.

It's not unusual for the earlier type oil pump set up to exhibit such behaviour (my old Wedge used to suffer this issue) You could try changing the oil pressure relief valve for a new one or up graded 'tadpole' type. You could also change the oil pressure switch which may have become a drama queen

Low oil pressure on tick over isn't a great concern on RV8s as flow is a more critical.

Where is the oil pressure switch..?

there is a nice spare hole to add a temp gauge

can`t see one on my car how do you test it? and which light is it on the dash (MK1)

Mine was a yellow led in the middle of the clocks. but some peopes have been different from reading online.

it just makes earth to light the LED so you could test the LED by putting an earth on one of the contacts on the back. As far as testing the switch i'm not sure mate thats beyond me, they are only a couple of quid to replace if you are in doubt though

ps i couldn't see mine from the top i dont think, i changed it from underneath

Yours is the same age a mine. The light is built into the speedo.

So does the low oil pressure light uluminate by detecting a pressure drop from the preesure guage or is there another switch somewhere .

are you able to check from underneath as there definatel should be a switch, seperate to the gauge sender
