Hello, I’m wondering if anyone could give me advice on a problem with a V8 engine in a 3500s that is now running with low oil pressure.The engine has always run with good pressure 30-45 psi, however on a recent short trip the pressure gauge dropped to around 15psi with the warning light coming on at idle. There is also tappet noise from the engine.
I took the car to a local garage where they ran an engine flush through it and changed the oil (20/50) and filter along with the oil pump pressure relief valve. The oil pump is not suspected nor the oil pickup. Pressure test confirms that it is low and not a faulty instrument gauge. The issue was not resolved and have been advised that the problem is probably bearing related and an engine rebuild or new engine will be required.
The main bearings were replaced 20 years ago (less than 10K miles ago – current mileage 70K) along with the cam & followers. The car is serviced regularly, although it did have to sit unused for a period over lockdown.
Just wondering whether anyone with experience of such V8 issues could help shed any light on this. I’m just trying to work out potential next steps.
Many thanks for any help or advice.
