Is this a 216 or 235? I agree with Jerry.. NO WAY is that going to take 40 minutes. Complete removal of the oil pan, then how do you even get to the block half of the seal without removing or at least seriously loosening the crank? Then angling the crank with the front cover still on could cause a bad spot on the front seal.
Am I missing something guys? The crank has to be out of the way to get to the whole rope seal? This is worth asking because, Chuck, if this guy isnt familiar with these engines, you are taking it to the wrong place. It could end up costing you way more than you expect. If its a 235, get a neoprene rubber seal. It will last longer and do a better job.
