Timing Belt Change

[VXR]

I thought that our VXs had a non-interference engine. So if the timing belt went it would not cause engine failure. Can anyone clarify

I am 99.99% certain you are correct. Engine damage from a broken timing belt would most likely NOT occur. However, I don't want to find out what does happen when something goes wrong under there.

The jury is still out on the interference issue. The specs indicate a positive clearance on the valves so THEORETICALLY yes, loss of the timing belt won't trash your engine. I'm not going to be the one to find out.

This comes from a training course for Isuzu techs on the new '98 3.5L engine.
We have a non-interference engine-

Just the fact that it is way easier to change when all the cams are lined up properly is all I would need to know. If the cams get out of time it is a pain to get them back in time. It is much easier to get everything lined up ,remove old belt ,install new belt with marks aligned and be sure that you will not be taking it back apart. I used the instructions from the vx manual, it was a piece of cake. If you are using an aftermarket belt , make sure to put marks on the belt before you remove it and make sure they line up with the marks on the new belt. The marks on mine were off it was a good thing I marked it and counted the teeth between the marks to make sure they were correct. It took maybe 5 to 6 hours. I remember someone saying that they had bent valves from a timing belt failure. So the jury is still out on the interference issue. The question is do you want to take the chance of having to also remove the heads and replace valves when you install the new belt? shawn

Well shoot!.....

I could have been using my DEWALT 1/2" 18-Volt Hammer Drill right now instead of being comfortable in the fact that my timing belt wont break.

Oh well, responsible decisions continue to take away my fun.
