Rear Main Seal Replacement

[Transformula]

Here is a little write up on how a rear main seal is replaced on a 1985 C10 with a 350. I'm sure all 2WD v8 chassis are similar from 73-87. You don't even need to raise the engine. A heplful hint: Drain the oil the night before and put the plug back in. The next morning, drain the remaining oil. Now the oil had a chance to drip off the crankshaft, oil pickup, etc. and you don't wind up with it all over you or the ground. I put down a rubber mat for comfort and keeping the floor clean. Then I turn the crankshaft so that the timing mark points to the ground. Remove all the oil pan bolts and pry it free from the block.
