190E 2.3 Timing Chain Noise

A 2.3 chain tensioner has a ratchet in it. Unlike the V8 tensioner that are
just oil pressure controlled. As a 2.3 chain stretches, the tensioner comes
out to take up the slack but it cannot retract. When the tensioner reaches
the end of its clicks, it can extend and retract like a V8 tensioner. BUT at
this point your chain has stretched to its breaking point. You need to
replace the chain very soon!
To replace the tensioner, you will need a couple of big allen sockets. You
remove the center allen plug. Remove the spring. Remove the housing from the
timing cover. Pull the plunger out. To install: screw the housing into the
cover tight. Push the plunger in [the ratchet is the spring ring on the butt
end]. Install the spring. Put the end plug on the allen socket and PUSH HARD
to compress the spring AND turn the allen to start the threads. Have fun!

Another project that I'll never have time for.

Since I think that the chain is fairly new, I'll start with the tensioner.
Is there anyway to test the chain for stretch? The P.O. might have used have
used a cheap chain.

Thanks for the info.
