I have a Mini Cooper 2007 16 automatic, bought the car in January 2020 for my wires a first car,
on test drive everything seemed ok however after a few days we noticed that theengine oil warning light was coming on when driving for around half hour, this only comes on whenyou come to a stop or at low idle ?
I have done some work in the engine, firstI popped in a digital gauge to get a good oil pressure reading, 30 psi on start up when cold,as the car warms up I pressure starts to drop and after 10 mins it is down to 8 psi but does flick between 8 and 0. Then the light comes on.
so I removed the oil pump and found itwas badly damage. When I look a bit deeper it appears that the timing chain had failedon the passed and been replaced.
Didn’t do a proper job as debris from the failure were still in the sump.
I get a new oil pump, full timing chain kit, oil filter housing unit and replaced everything.
mean the car to test thinking all would be fine but I still have the same oil pressure problem. Makes 30 psi on cold start up but then drops to between 8 - 0 psi. And that’s with a digital Parker gauge piped in where the oil pressure switch lives
anyone go any point to look at as I’m at lose now
