Hello all,

I have an '89 944 Turbo which I've had for around a week now. I've done the usual maintenance on it since buying, cambelt, balance belt, oil change with filter and I'm awaiting a new air filter. The oil pressure gauge seems quite intermittent although the sender looks as if it's been replaced at some point. When I turn the ignition on the gauge jumps to around 2.5 then when I start the engine it goes straight to above 5. If I'm driving with any throttle it stays there but if I lift off it drops to around 4. I've not had it drop below 5 on idle though. What could this be?

Thanks in advance.

Sounds like an electric fault if it jumps to 2.5 with just ign on

What's the best way to go about this then? Is it easy to rewire?

Thanks, James

I took a video to show what it's doing:

Check ya rugby balls on the rear of the cluster clean them up see if that helps

I presume that's following the "check your balls" thread?

James
