1990 Chevrolet 1500 Pickup Question: Rear engine oil leak
If it is coming from the bell housing, flywheel inspection cover, and is motor oil. It probably is the rear main oil seal. This seals the back of the crankshaft between the block and flywheel. - torque wrench
I think it is worth replacing the seals. It runs/looks like new but do you think it is advisable to invest that much money in it?
I hear it more when I am slowing down
