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.
