the motor had around 12,000km's since the rebuild with all 3 oil changes from run in completed at the right intervals. i.e. mineral oil @ 0km (i was told), 500km and 1000km, then motul turbolight 8100 at 1500km then @ every 3000km interval thereafter.
it wasnt my job to check if the oil pump was shagged before it was installed so i dont know if it was good to go, if it wasnt im sure i would've been notified.
i didnt have an aftermarket oil pressure gauge so i dont know what it was like, and i cant go off the standard one because it stopped being reliable around a year ago. when i picked up the car i was told by the owner of the business that "oil pressure was off the charts".
i dont have any other info for you.
