1992 Isuzu Trooper Timing

is it a sohc or dohc? either way you can find it on autozone.com. I don't work for autozone but I do a lot of my own vehicle repairs and get most of my parts from them. I have a 1992 trooper with the 3.2 dohc. on my truck you set teh #1 cyl to tdc then you can line up the cams.on mine there are marks on the heads at about the 1 o clock position. that's where the cam sprockets line up. the crank sprocket has a mark on the block, but if #1 cyl is at tdc it should be good. just make sure that the belt marks line up with the cam and crankshaft sprockets. ( I used wooden clothes pins to keep the timing belt on the cam sprockets while I put it on the crank sprocket). It's a pain in the butt but it can be done.
