I removed the valve cover and looking down the timing chain on the loose side , left facing the engine, the chain guide is broken and the chain has jumped a couple of notches. My engine is the 2.6 and is 4x4, would it be easier to pull the head to remove the timing chain cover or jack up the engine and remove the oil pan, it looks like a real pain to remove the oil pan, and I could do an inspection on the head and make any repairs and change the stem seals. My baby has 222,000 mi. Thanks
