351c Rear seal

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   So I have this major oil leak apparently at the rear main seal. This, just a few months after a complete rebuild. My next question would be this: Can I remove the oil pan without raising the engine, and be able to replace the seal without dismantling too much else? I have no way of raising the car except for ramps, and a hoist would be a rental. Am I getting in too deep, or should I fork over the bucks to a garage?

	fork over the cash if you dont have to right tools or the right buddies that have the right tools. But a rear main needs to atleast movet the tranny somewhat out of the way and dropping the pan without lifting the engine would only benefit you an inch if that sorry for the bad news but sometimes that is the way it rolls
