How many miles are on it? How do the teeth look on the timing gears? How much slack does the chain have?

They aren't terribly expensive, however you do have to drop the front of the oil pan to get the timing cover off and risk damaging the oil pan gasket. That too can easily be fixed by strategically placing sealant on the block, pan and w/in the newly formed cracks of the gasket before bolting the pan up.
Nothing is ever easy.
How many miles on the engine/timing chain? Any modifications?

At 140k, I would put serious consideration into changing the timing set while you have things apart. Also all timing cover seals while you're at it.
