My D90 sat unloved for a while, and lost it's oil pump prime. I got the pump re-primed, and have oil pressure again (the oil light turns off). I unfortunately have a knock in my engine now. A mechanic friend told me that it was not a problem, and I should let it run and the knock would go away in a while (he said it could be 20-30min). Because of the knock I have tried not to run it, and it hasn't been running for more than a minute or so at a time.
What's the consensus? Is my buddy right?
I got your JEEP thing, now it hurts when I pee!!
