Ok heres the situation. Pulled the engine and transmission to change a
rear main seal out and reseal the steering. I had to turn the engine,
and I turned it the opposite direction on accident. I had to replace
the oil pan gasket and there was a piece of white plastic in with the
oil. Its back in the car and it wouldn't start. I pulled the valve
cover and the chain is still there, but it felt REALLY loose. I could
almost get my pinky between the chain and the sprocket. What kind of
damage do you think has been done.

Sounds like the timing chain tensioner is shot... You will have to realign
all the timing marks.

There is only one... passenger side... comes off with two bolts...just look
it up at parts store online and you will see it on your engine.

More than likely, that plastic piece came from the inboard upper rail on the drivers side head. When
the chain stretches and the tensioner no longer can compensate for the slack [after about 100,000 to
120,000 miles] the chain movement breaks off the lower end of the left inner rail.

#95 here:
http://www.detali.ru/cat/oem_mb2.asp?TP=1&F=126037%5F287&M=117963&GA=7...2E30231

Do NOT start the engine!!!!! The chain may jump and bend the exhaust valves on the drivers side.
REPLACE both 95's, 83, 47, and the chain NOW.

They started out in life a very light ivory white. Age and oil darkens them. The darker they get,
the older they are.
