I have a 1992 Isuzu pickup 2.6L that is leaking oil from the oil filter housing. Does anyone have picture or a diagram on how to remove the compressor so i can remove the top bolt on the oil housing unit. I removed the belt and the front bolt but can't tell what type of bolt is holding the rear of the compressor. I need to remove the compressor to reach the top housing bolt. Thanks for any help!
