[W126 Coupe] Chain Jumped

[Pavel]

Yeah, I'm not turning the motor over until I pull out all the rockers,
spark plugs take off the oil pan and put in a new tensioner.  What I assume
happened was a weak tensioner, records on car state that they used SAE
15w50 oil in it a no-no here in Minnesota when temp is about 15 deg F.  So
what i assume happened was they tried starting it tensioner did not get
enough pressure chain was loose took out one of the guide rails and jumped.
 What will happen to the car I will fix the motor then supercharge it using
mega squirt fuel EFI management system once I have that car and system
running good i will part that car out and put the engine in my 380. So if
anyone needs parts let me know, the car will be parted with in 6 month if
all goes well.


>From removing the valve covers I have found that everything is intact

except all the guide rails and timing rail is busted.  The tensioner has a
piece missing from its pressure cylinder.  The only damage I could see on
the head was a tiny piece was broken off where the tensioner goes into the
passenger side head, I think if I find it in my oil pan i can JB weld it or
even having that piece missing I do not think will effect how the car
operates, assuming the valves are not broken.  The timing chain has tons of
slack on the tensioner side of the chain.  I will start messing with it
during my winter break from school.
