Fraid you're gonna have to pull off the timing case.
The piece that is broken off (find it here
http://www.detali.ru/cat/cats/?cat=mb ) is situated between the two
camshafts. Now the problem is that you have two holes in the cam cover.
Why? Because something broke off in the bottom, got dragged over cam A,
smashed a hole, smashed the sliding rail and dragged over cam B and
punched another hole in the cover and did God knows what else.

Looking at that, only chain guide 104 sits inside the chain, the rest
all appear to guide it from the outside. I am starting to think
something nasty happened and may not be a guide rail fault, as I can't
see a piece from guide 104 going all the way round to the camshaft
sprockets. However I stand by having to pull the front cover off the
engine to inspect all components.

I've never looked at one of those engines, so it's hard to say - did
you pull the other side and compare?
Can you get someone to crank it by hand while you watch the cam
followers go up and down? Don't know how you'd tell if valves were
bent other than to see if they go down and come back up.

Pulled the valve cover today to survey the damage. Looks like there is
supposed to be a slide rail at the top of the head under the chain toward
the middle side of the engine, which is not there. Is this correct? Looks
like its broken which caused the valve cover to break. Chain is intact and
it does not appear at least from the outside that there are any bent valves.
So, opinions on what needs to happen? Does that slide rail need to be
replaced or does it need to be torn down and all of them replaced? If just
one one, is there a way to replace it from up top? Looks like I might have
to split the chain and put in a new master link. See pics
