I have the same model, DOHC. The bolt is a bear to loosen. I use an impact but I had to remove the radiator to use it. I have since seen where if you CAREFULLY use a long breaker bar and wedge it against the frame or other hard point and then quickly bump the starter it will break the bolt loose. I suggest unplugging the connectors to the coil packs in order to assure the engine does not start. I have seen this done but not on an Isuzu, but I see no reason it would not work, as it is a right hand threaded bolt. Also, the harmonic balancer is a slip fit so it will usually come right off if you are careful to use a remover or carefully apply even pressure to it on opposite sides. Good luck
This engine is a non interference engine, according to the experts. There is a warning in the manuals, but I am pretty confident that you should not have any damage unless you really over revved it or drove it a long time with it mis timed, .....which usually cannot be done as the engine will run poorly if at all.
One guys opinion.

I am in the middle of changing the timing belt on my 02 trooper. I cannot get the serpentine belt tensioner off to get to the timing belt cover. I have taken all bolts out but there either is a dowel pin or another bolt inside the tensioner. Any suggestions would be greatly appreciated.

My '95 Trooper quit running. It turns over and tries to start but it's as if it's not firing. I assumed it to be the timing belt needs replacing. Anyway, I started pulling spark plug wires to take out the plugs as the Chilton suggested and when I got to #3 plug the wrench came back drenched in oil. What's the significance?

well You need a long !/2" drive Breaker bar or at least a 24" craftsmen (strong one) and a pipe over it for leverage(mayb). I have a 32" I got from harbor freight. Use a small socket not a long deep one. Use a 14" pipe wrench tighten it up top lip inside of
pulley bottom lip tight against outside of pulley lodge other end against frame or something very solid and pull lefty loosey righty tighty

you need new grommets that go in the under side of the valve cover.that will stop the oil getting into the tubes

That is due to bad spark plugs or cables, or maybe the O2 sensor too.

Have a 3.2 L DOHC motor in a 97 isuzu trooper. My timing belt has gone out and I am looking to replace it. I am wondering if this motor is an interference motor, an if I could have incured damge to my valves etc when the belt failed. I am torn between replacing the belt or removing the heads to see what, if any, damage their might be. any comments and/or suggestions would be greatly appreciated.

Pull the head and check. Nothing like replacing the belt to find that valve damage has been incurred.

There are 2 bolts hiding behind the tensioner housing the spring
