So I recently bought an el Camino from my uncle that has been in my grandpas barn for about 20 years. I want to remove the oil pan to clean out any sludge that may be in the pan but it looks like the pan is too long to take out without hitting a cross member. I have no way to take the engine out all the way. So would I have to lift the engine to get the oil pan out? If so how high? What else besides the engine mounts would I have to loosen?
