I am changing the timing chain on a '99 astro. I can't remove the oil pan. I have removed all the bolts at the bottom of the pan (10), the ones attached horizontally (2), the ones for the lines 1 left 1 right, the starter and the oil filter. The oil pan will not budge even with a few blows with a mallet. How do I remove the oil pan?
