Hello Peycho, 

You will need to tell us exactly what has been rebuilt on the engine and what hasn't.

Kind regards,

Gareth.

Thank you Paycho,

'....oil pump ...replaced ....if necessary' may hold a clue. 

If it were mine, I would be getting the actual oil pressure measured when the oil is hot ( only after a 10 mile run) so that you will be able to know if it's simply an oil pressure sensor issue, or an actual a low pressure problem.

How many miles has the car done since the engine was rebuilt? 

Have you notified the rebuilders? 

Kind regards,

Gareth.
