oil pressur

[pepe]

Hi need help here please

3.2 targa 1985

my oil cooler pressure has dropped and the gauge moves a lot now

...it use to stay up at the top

now moves a lot in the middle...just been serviced with Mobil oil and the oil is correct on the dipstick

not the druck pressure gauge ...its the gauge shared with the fuel gauge

Thanks in advance once again

I think you are referring to the Oil Level Gauge not the Oil Pressure If so this can be eratic and it only reads accuately at idle.

+1, mine jumps all over the place, I ignore it most of the time.

Make sure the actual pressure gauge is showing around or just above 1 at idle when hot and 4-5 on throttle

If the gauge stayed at the top before the service, it's because it had been over filled and I'm surprised you weren't leaving an oil slick behind you everywhere you went. The gauge can only give a meaningful reading when hot and at idle - and the hotter the engine, the higher the reading. However, the only accurate way to check the level is on the dip-stick. Read your handbook - it explains everything.

My level is all over, and should only be used when hot, at idle and on the flat.

I remember reading a Peter Morgan article where he said pressure should loosely be RPM K + 1 when moving, so 1000 RPM should be 2 on the oil pressure. Mine generally follows this pattern, until cruising in 5 where it doesn't really go over 4.

Which is what it's meant to do, so either it was overfilled before, or it was stuck.

My money is on a stuck gauge. I remember a friend who had a 993 encountering a large hole in the road he couldn't avoid and then being delighted that the "pot hole fairies had fixed his oil level gauge" which had previously read a continuous full.

Why??? If it jumps all over the place when the engine is hot, it's behaving normally!

Hello All
I agree that the oil level gauge is unreliable at the best of time and specially when the car is moving. Mine spends most of its time stuck at maximum.

However, when it rains and I use the rear screen wiper the oil level gauge starts to work and to say it is perfect is an understatement. You can watch the oil level rise and fall as the engine is reved or the car driven from low to high revs. Any thoughts?

I always use the dip stick, I just don't know how owners of the latest cars do without one.
Regards
ALAN

The only thought is that as per the manual, the level is only relevant when the car is stationary, flat and up to temperature. What ever it happens to do at any of time no matter how odd doesn't tell you anything.

I too would find it rather odd not to have a dip stick, would make changing the oil an interesting process.
