100% true. Replaced the timing chain on my 83 300D at 335,000 miles on the original chain. Made this repair right before 10,000 mile plus road trip. Cheap insurance, 900 bucks spent with cost of new chain included, done by trusted shop down the street.
Performance of the car changed dramatically, as whunter said, timing had not been adjusted for 300,000 miles, and slop in the chain was directly affecting performance. Felt like another 15 to 20 hp added.
