low oil pressure

[thatch]

Happy New Year everyone!

Hope you have been enjoying the nice weather, in conjunction with days off work (for a change) and been getting some miles in!

I have noticed my 4.3 BV 1992 Griff is always running on low oil pressure. Between 0 and 25 even at 3-4000 revs. I know that they do run relatively low, but it is still disconcerting to see the gauge go down to zero, and sometimes fluctuate even if the revs are constant!

Should I be concerned?

Yes, you should be concerned.

Could be just an electrical fault with the gauge, wiring, or sender, but you need to investigate it as a matter of priority - the pressure should not fluctuate at constant revs.

I'd second that. Start with the gauge but don't risk running it with no oil pressure until you're sure it's OK.

Good luck.

It turned out to be the sender unit.

Changed and sorted.

Thanks for the help.

Thatch,
Our oil pressure reads low too.
Where did you get yours from? It's certainly worth a try

mine was reading below 25 PSI, but more importantly fluctuating at constant revs.

I got Offords to check pressure using a wet line gauge which showed 28PSI at idle 45PSI at constant 3000RPM. But more importantly - it was constant

fitting a new sensor confirmed the wet line readings on the dashboard.

cost of job = £40 sender + £40 labour = peace of mind!

I have just had a pressure transmitter fitted the oil pressure was idle 15 psi 3000 rpm 32 psi
NOW idle 30 psi 3000 rpm 55 psi talk about peace of mind
Gorners have a few in stock

£80 per hour labour!

It took around an hour, to test the wet line pressure, and to fit a new sender. I was stood with the car all the time, and had discussions with the technician.

Whilst I am sure it could have been done quicker, I was a major distraction and enjoyed doing it!

£40 well spent IMHO
