oil pressre warning

[harvey m]

Hi all
Started my tuscan mk 1 up the other day and the dash warning light for zero oil pressure came on
Went to a local garage and they said it was probably a faulty sensor
The car has plenty of oil in it and the engine sounds fine
Had a complete engine rebuild by dom last year
Any idea's as to fault
Cheers

Wouldn't risk it, get it recovered to either you local specialist or Dom

Yes. 100% do not use it especially after rebuild.

I'd probably agree with above??

I'd 'phone Dom....He may suggest getting a new sender on the engine - he may even get one in the post to you?

However, for the peace of mind, right now, I'd be organising my breakdown/recovery service to get car up to Coventry.

The senders do fail/deteriorate. I commented on only 9psi at hot idle on my 4.3 rebuild when car was in for 1000 mile service - sensor changed and hot idle pressure jumped to 25psi. Can't understand why this component isn't renewed automatically at rebuild - it's not as though it's expensive at 60 quid.

"hot idle pressure jumped to 25psi"

Even this 25 psi is not correct i think, should be between 12-16 psi at 750 rpm and 85-90 deg C.
All this senders give different readings.

Agreed, Uwe,
I just wanted to highlight, and hopefully, reassure the OP...THAT the likely/best outcome is that the sensor has failed. (And there have been loads of posts on here and on the V8 engined TVR forums that the sensors and gauges can be an issue)

I gave my figure as examples...I haven't had a calibrated gauge on the sensor....I was just mentioning that with a replacement item on, the indicated pressure was 'better'. Which made me feel more comfortable.
