Cummins N14 Celect Plus Vibration Noise

Hello every one! I am so glad to be part of this forum. I have a Cummins N14 Celect plus which I am struggling quite a bit with. Everything was perfectly fine with it untill I did a oil change. After I changed the oil and oil filter I started it up but then had a vibration noise that was not there before. I used the same kind of oil as always, so no changes there. I checked everything but with no luck! I thought it may be the compressor as I was battling with the air aswell so I fixed the compressor hoping that that was the cause of the noise but no still the same. I changed the oil filter again as I did not use the usual kind I always used but still no change. checked the engine mountings,vibration damper, cab bushes, accessory drive,air compressor cooling pipe not rubbing on the block. I sounds almost asif a washer of some sorts came loose and is runnig with the engine. Any ideas? Any help will be greatly appreciated as I don't have a clue any more! Thanks
