Oil pressure guage - going on off on off on off...
« on: 22:02, Sun 11 January 2009 »
Hi there, picked up my R5 turbo from a member on here yesterday, over the moon with it!

on the way home though, had a scary experience. Ive got alot of mechanical sympathy for cars so im always watching all the guages and driving steady and off-boost for motorway driving, and i noticed on the motorway suddenly the oil pressure just dropped!

It went straight down to the bottom, luckily there was a turning for the services so i let straight off the accelorator, and managed to roll into the services.

When i stopped, the guage went back up again!
I checked the oil levels, they were fine. There was no smoking, tapping or noises, and no drips under the car,

i drove home steady, the oil pressure seemed fine, but sometimes too high. Today though, it did the same, guage saying completely no pressure, twice, and high at other times, never really in the middle...

Im just wondering on these, is there an oil pressure relief valve or something that could be sticking open or closed? Or could my guage be playing up? are they electric guages or mechanical?

sorry for all the questions and the really long essay post :) i appreciate all the help i get, and glad to be a new member here! :)

Ok great will do, i thought they usually worked or didnt work, i didnt know switches could be intermittant like that so thats why i asked,
ill get a new switch in the morning before i drive it again,
i was worried that there might be a pressure relief valve somewhere sticking, like on minis,
cheers

but could also be the connection dirty have a check if they are give them a quick clean and try it

to find the oil preasure switch follow the oil feed pipe you fin it on the bottom of the pipe near the sump

Nothing to worry about.

As already mentioned either dirty connections as they get filthy down there or a dodgy sender.

The only time to worry is when the oil pressure warning light comes on, but usually by then it's too late.  :(

There was a guy from work who had one with a bike engine in the boot. It was a right little screamer.  8)  :lol:
