Leaking rear seal; big deal or not?

[68L79M21]

You do not have to pull the engine to replace the rear main seal. I did it on my '68 L79 Corvette. With the frame of a C3 it is not hard at all to get the oil pan off with the engine in the car - no crossmember under the pan. The hard part for me was getting the old upper seal out - it did not want to budge. I took a piece of round brass stock, ground about a 1.5 inch length down to the size where it would fit in the seal area, then was able to get the seal out. New seal GM p/n 10121044 and sealant on the main cap per the directions. Have put probably 20K miles on the car since.

Belair..You are showing your age. I have one of those tools but they were used for the old rope type seals.
