Dealership Problem

As a dodge/Chrysler dealer tech, my guess is that despite being quite low on oil when they replaced the split o ring, id bet the motor is just fine, and I say that because, due to the unique way that this 1.4 motor works, and still ran, id say oil pressure went down, but it was enough to keep it running, check this video out, [ame="https://www.youtube.com/watch?v=Td9Gz_h7Qpg"]How Fiat MultiAir Technology Works - YouTube[/ame] . on multiair engines, the only way to actuate the intake valves is to have oil pressure. no oil=no start condition. when the fiats first came stateside, dealers had a problem with them sitting too long and then not starting. these mulitairs need to be started on a regular basis, Id bet once every two weeks would be sufficient. what im getting at is that there had to be oil pressure in the vehicle, otherwise it wouldn't have started.
