I had my engine rebuilt by a machine shop about 40 miles away from me last fall. It was run to break in and check for leaks at that time. I brought it home put it in the car and installed the 4 speed. As I was doing this we noticed a couple drops of oil coming from the rear of the motor. Out comes the tranny to look what is wet. The oil was coming from the rear main area, but after removing the trans. it stopped. We put everything back together. The car was loaded on a flatbed -not running-to go back to the body shop for hood, fenders, and painting of the black stripes. After it was unloaded and set overnight there was 4-6 drops of oil under the clutch inspection cover(surprise). After getting it all toghether and running I will get the same 4-6 drops after every ride. Nothing serious but I want it to stop leaking. The shop that rebuilt the motor wants me to drive the car to them and help take it apart to redo the permatex(I am guessing around the cap?) I would then have to leave the car there overnight to let the silicone dry. I would prefer to not have them work on the car and am wondering how big of job it would be for me to do in my garage. I can't imagine the seals could be bad. Could the upper one be left alone? Can the trans. stay in the car? Thanks for your input.
