So i have an LD9 Twin-Cam 2.4l motor in my 1997 grand am, 174,000 miles. It has had a bad wrist pin for over 2 years now, and the noise and vibration has slowly gotten worse in that timespan. What additive/oil would you guys recommend to help quiet and/or cushion the bad wrist pin? it isn't cost effective or worth my time to fix the problem, considering how old the car is and what i paid for it. so for now, i'm just looking for something to "mask" the problem, aka quiet this stupid wrist pin down! maybe a thicker oil would help?
