Timing chain replacement as preventative measure?
A question to the experienced or those that learned the hard way?
I have a Mercedes 300 SD that had a sudden timing chain snap and the consequences...well, total destruction of the engine and a new rebuild was not pleasant or cheap. Anyway, the genius MB mechanic told me that I should have had the Timing chain replaced every 200,000 kms.
Now, I have this very dear Ford 350 XLT 1990 7.3 Diesel. Just did 4500 miles to Texas and back to Ontario and was it fun to sleep in the open, under the stars, with 104 F. Frightened some people when a body suddenly arose from the back of a pick up. Anyway, you can see, I think this is the greatest truck and even though it is getting on in age, it runs like there was no tomorrow. 75MPH all day. Just feed some diesel and that's it . Does not ask for anything else.
However, want to know if and when, one should change the TIMING chain as a matter of course or just to avoid the Mercedes scenario.? Anyone, please.
And is it a tedious and expensive job. Many thanks.

The old IDI diesels Don't have timing chains. All of the timing is done with gears on the crank, cam, and Injector pump. The only way to jump the timing is to jumpp a tooth on one of the gears and the likelyhood of jumping more than one or two teeth is low.
