pressure guage

[Guest]

hello all - really good forum, full of interesting stuff.

here's my first post, and its a potential problem i think. I recently had a new clutch put in, and when i collected the car, the dash oil level guage was off the scale. i went for a run to warm the oil, and when i checked the level by dip stick it was up to the maximum, but no further. should be okay i thought, but i have heard that you should always run a litre or so light to allow for heat expansion. time didn't permit dropping a bit out the bottom though, and i thought i'd skate away with it for a week - only about 50 miles or so.

now however, the pressure guage is behaving very oddly - it will jump around the scale from 4 bar to 2 when the revs are constant (the engine doesn't seem any different, and performance is unchanged). no smoke at any time from the back.

have i:

a) a knackered guage. []
b) a knackered sender (and where is it?) []
c) a more serious engine problem. [:'(]

i've dropped the level now, but symptoms persist. help hugely appreciated.

Adam,
Sound like a bad earth somewhere to me, probably got disturbed when the engine came out for the clutch.
The pressure sender, from what I remember, is on the RH cylinder bank rear most and at the top of the engine. It looks like a small metal canister with a black plastic knurled connector on the top with a single wire.

Hope this helps.

Phil,

thanks for that, i dropped another half litre or so of oil, had a twiddle with sender (thanks for directions), and both sides of the guage now seem ok. I can also now see the level needle move occassionally - just to re-assure myself that it actually works!
