Well, I'll give it a try. When I did the chain on my diesel, I was able to get a crimpable master link. Well, this will certainly be a lot easier, but it also makes my crimping tool that I bought some years ago for MB double chains quite useless for this job...

Timing chain failure effectively just stops the engine (permanently) when it occurs. Other than removing power assist from steering and brakes, you can still control the car quite well, just as if the engine would die for any other reason. I had a BMW that died when the timing chain (single) failed at highway speeds. Just turned my blinker on and pulled off the road. The sound of the failure clues you into what happened immediately. The only problem that can occur is the car speed will still try to turn the crankshaft through the transmission if you are not quick to shift to neutral. If for some reason the chain will still try to feed by the crank's speocket, the chain can bind and damage either the crank, the sprocket or worst case the allum block. If this happends, rebuilding is unlikely.

Thanks,
