Hi Max,
How many miles are on the engine and what kind of oil has been used?
Thx -

For posterity, using Ned's method, I got very similar results (between 2
and 3 degrees of wear).

Answering my own post here. Searched the archives and found an exchange
between Ned Kleinhenz and Marshall Booth, here's the key part below.
Ned if you're still on this list, I'd like permission to also post this
great tidbit on the MBCA forum and credit to your name.

Glad I took Marshall's advice and replicated the chain stretch
measurement on my '95 E300D with the OM 606.910 engine. My first
measurement on Saturday was 4 deg.
The subsequent measurements, today, were 3 deg, 2 deg and 2.5 deg.
Think I'll keep this chain and check it again in 30 or 50k miles.
I discovered an important trick that other 606 engine owners may want to
know - The cam can be indexed for #1 piston TDC by running a pin through
holes that align the left cam gear and the front cam tower. One of the
bolts that holds the cam cover on the head is the perfect size to use as
this pin.
This bolt will fit tightly enough that I estimate the bolt will only fit
through both holes within < 1/2 deg of crank rotation.
When looking at the engine from the front of the car, correct crank
rotation is clockwise. To measure chain stretch, you must approach the
index postion only from the clockwise direction. Backing the crank off
a fraction of a degee reverses the play in the chain and makes the
measurement meaningless.

Subject: [MBZ] OM606 Timing Chain Wear Measure
Dieselvolk,
I'm trying to measure the timing chain wear on my '95 E300 (OM606). I
cannot for the life of me find any marks on the camshaft at the #1
bearing tower. I've made this check on OM617 and OM603 engines, so I
know what I'm looking for, but this OM606 has got me stumped.
Anyone know the trick?
There is a set of marks on the third cam bearing tower and the primary
camshaft (two camshafts on this engine, remember), but they are not
easily aligned for a precise measurement. When I line them up, it looks
like timing chain wear is about 4 degrees. There's also a hole in the
gear on the second camshaft, and that hole can be aligned with a hole in
the #1 cam bearing tower. When I line that up, I measure about 10
degrees of wear!
Very respectfully,
/s/
