There is a special tool to remove them, designed for removal w/o breakage.

MOST of the time they break anyhow. If you are replacing them make sure not to allow pieces of them to get into the engine.

YES timing chains can jump on the M119 engine, have seen at least 10 with bent valves & broken camshafts.

The tensioner is always at fault.....lack of oil changes are the most probable cause of tensioner failure!
