Engine Performance problem
1998 Dodge Durango V8 Four Wheel Drive Automatic 104019 miles
i have a 5.2 liter with 104,019 miles. I have had my oil pressure gage drop to 0 at times in the past(a couple of years ago) when I got on it(driving fast to get to work on time lol). If I let off of it pressure would go back to normal around 50-60. A couple of months ago it was dropping off to 0 when just normal driving and usually oil presure is now around 30-35. I took it to my machanic who changed the sending unit. At the same time I changed the oil and filter. I substituted 1 quart of the oil with lucas oil as my mechanic recomended. I had no issues oil presure went back to 50-60 until about 2 weeks ago. I have only put on about 1800 miles now it is dropping to 0 again and the oil prssure is back down to 30-35 it comes and goes as I drive it drops when I accellerate and if I let off or stop it comes back. Sometimes I can drive 5-10 if the engine has reached full temp of 190 with no issues. Then beyound that it will drop to 0 again as before. The oil is not milky no leaks are seen and oil fluid is at normal level and it is clean looking oil. I just came back from my machinc he is baffled by this he watched and saw what I just described. On my way back home the oil pressure momentarily went back to 50-60 then droped back to 30-35 in only 1/2 mile drive. Then I went back to mechanic after talking to another mechanic he recomended and the pressure is back up to 50-60. The answers I am getting are the pick-up line screen is partially blocked, the returns are blocked, and the oil pump is going bad if replacing the oil pump it has been recommended to go to a high volume pump. Can you please help me? Thank you Dave
