I can't seem to get the last bolt off on the oil cooler, its covered by the timing cover. What all is needed here for removal? Also I'm thinking while I'm in there I might as well put in an aftermarket external oil cooler and clean up that area(thinking about relocating the alternator also). What is the best way to go about this? I saw this kit from stm http://www.streettunedmotorsports.co...oil_cooler.htm
