pyanev Posted January 9, 2019 Share Posted January 9, 2019 Hello i had a rebuild on my engine soon , and i have a problem when i drive the car on sport mode and after i push it a couple times the oil pressure light is starting to appear on the dash board . If you tell me what can be the problem and why its keep doing that i will be very thankfull . What could it be a oil pressure sensor or filter or something else ? Thank you Quote Link to comment Share on other sites More sharing options...
Magnet Posted January 9, 2019 Share Posted January 9, 2019 Hello Peycho, You will need to tell us exactly what has been rebuilt on the engine and what hasn't. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...

Magnet Posted January 10, 2019 Share Posted January 10, 2019 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. Quote Link to comment Share on other sites More sharing options...
