Recently purchased a 165d, after a couple hours of use decided to change the oil and filter. Used rotella 15/40 and a fram filter(will be changing to wix). After running about 45 min lost oil psi replaced sending unit installed oil gauge still no psi did have a little flow over the valves. After studying diagram of lubrication system in owners manual I took filter off the filter and removed what I assume to be the oil pressure regulator(steel ball,spring and back adjusting nut) dismantled it cleaned and reinstalled it. Restarted engine and had oil psi. Next day went back out started tractor no oil psi repeated above procedure and got oil psi back. About 8 psi at idle and 35 at ~2500.
Called priior owner and asked whaty oil he used. He said he used delvac 15/40. Could switching of oil cause this problem? I know that in some diesel engines switching of oils can cause oil consumption for the first few oil changes. Had this happen on my powerstroke. Any help on this issue would be appreciated.
Thanks
