I've read all the admonishments about updating the timing chain, lest it'll break, destroying the engine; and by golly, I'm a convert. But...
I just read an ad in my area for a 91 560 with a timing chain failure and "bent valves". I assume nobody has taken this engine apart to verify the damage...it's more like, well, if the timing chain breaks throw in the towel.
So, the real question is...what really happens to an engine when the chain goes? What's the worst case? Not hypothetical, what's really happened? If it were "just" bent valves, wouldn't the engine be rebuildable? If someone GAVE you such an engine, wouldn't you open it up, or would even that be too "disturbing"?
Not to bring back suppressed memories, but has anyone had this happen and is still around to talk about it? Thanks, Dave
