i have a manual at home, ill dig them out. but. you just do them up tight. as for the timing. theres a little mark on the 2 spider gears that you line up. very very simple.
also, it sounds like a piece of shit, dont buy it. my old auto was less than that, and i believe geo got his for less aswell. if you bide your time, youll get one in good condition for less.
you got a pic, im having a hard time remembering the wires from the ep. a pic should refresh me. if its the one im thinking. its where everyone whips the vac lines in for a boost gauge ^^
replacing cams takes about 15 mins. its as simple as undoing the fasteners putting new ones in and doing them back up. i have some spare cams if you want to buy some.
