Hey everyone...looking for some help. I've had some issues with Oil Pressure lately. I have a 6NZ CAT C15. I have replaced the Piston Cooling jets when I removed the oil pan and noticed they had broken off. Oil Pressure was great after that for a few weeks running about 60-65PSI on the highway. Now my oil pressure is dropping again and is down near about 50PSI. I know I have to replace the oil cooler and I am doing that this weekend. My question is do you think the bad Oil Cooler could be effecting my Oil Pressure?
Thank you in advance for your help
