I will be replacing the hall effect sensor in my 1988 244 after doing the head gasket in my 91'. I have found bits and pieces of information and a few pictures , but not enough to ensure my confidence of having all of the necessary tools, and the correct procedure so I don't render the car completely useless.
I've read that it is riveted in (why?), and requires drilling out, but not too far down for fear of drilling through aluminum. I also remember reading something about epoxying the sensor to the body after the rivets are drilled out.
A few questions I have:
How do you get the circular metal 'hall' off to access the sensor itself?
Is it possible to do with the distributor still in the engine?
These were the best sources I was able to find.
