Ive always thought it was a good idea to replace the timing chain when the engine is approaching 300k. My 84 300d was about to get a new chain, then got totaled. But someday, that engine will get a new one before I begin using it again. My uncles td had 250k on it when he snapped his timing chain, he loves the wagon so much hes having the engine rebuilt right now. When he bought the car, it wasn't in that great of shape mechanically, which tells me maybe the engine maintained was neglected, leading to an early timing chain failure.



Ive also heard that when your chain is near snapping, you'll hear a tick, or some strange noise. I believe it though, my uncle had driven the car to our house from LA (400 miles) and it was having that tick before he left. Went home and a week later it snapped.
