Ive taken a oil Pressure test today on a 2012 Bobcat T190 with the Kubota V2607 engine. At Idle (1050 rpms) it was reading 7psi of pressure. At Rated Speed (2200 rpms) it read 12 Psi. Other issue i got with this machine is the turbo leaking and smoking. I was told low oil Pressure damages the seals on the turbo. What could the causes for these issues
