Death of a /6
My First Mopar was a 74 Plymouth Scamp with a 225 Slant 6. I drove it probably 3 months after I got it and noticed the oil light would flicker at cruising speed and at a stop it would stay totally lit up bright red.
I put a mechanical gauge on it and at idle,was pushing 0 PSI oil Pressure and at cruising speed it would register maybe 10 PSI. I drove around like that for about 4 more months,and then replaced the oil pump. Oil pressure stabilized and the car never gave me any other trouble, No noises--Nothing .
I just got my 72 Swinger running and Ill tell you that car is a blast to drive with the Slant 6 and 3 on the tree.
