Oil Pump difference
I am in the process of putting a different oil pump on my car. I have found a small difference in the following 2 pumps and for future reference thought I would post the difference. I guess this would only apply to 83-86 without the automatic tensioner.
The 2 pump numbers are
944 107 104 9R
944 107 111 3R
Pump 104 has a thicker casting where the timing belt tensioner stud goes through it and requires the proper nut tightned against the oil pump, then the tensioner goes over the stud against the nut.
Pump 107 111 3R has a thinner casting where the stud goes through and requires the nut tightned against the oil pump and then a spacer that is approx 1/4 inch thick placed on the stud and then the tensioner placed on the stud.
