Hi rob4155, its easy to slacken the top cam belt cover to get a little bit of access to a bit of the cam belt itself for inspection. Just a couple of small bolts to remove to see if its slack. Not so useful if the teeth are missing.

But if the teeth have sheared off, you can turn the engine over and observe the cam belt not turning the cam shaft while the crank pulley rotates. The valves will be closed at this point if the belt is damaged so you won't be doing any more damage to the valves that has already been done (potentially).

Its not enough for a full inspection, but OK to see if its broken. The belt should last 150K miles or 10 years.

If you wanted a much better look you will have to remove the engine mount while helping to support the weight of the engine.

if it was running rough and now won't start i'd be doing an injector leak off test.
