I would think that they set the clearances too loose. What oil pump was in the motor? Does it have a plug that you can change the pressure spring in it? What color is the spring if it is changeable?
The oil pump is a Melling High Output pump. I am uncertain if I can change the pressure on it.
In a talk with a Melling tech guy, he did not mention that feature when I called him concerned with the 55lbs when I first installed the engine 3 years back......pg
