Ok folks, so gmog220d (Greg) helped me out a ton the other day. We got a few things sussed out: oil change, valve adjustment, checking timing with the 2mm method, pulling out my cam gear to see the offset key and were finally left with the question of what is a #18 camshaft? More specifically, we couldn't find the cam timing specs for the #18 camshaft, which is what my engine has on it. From the tag on the block, it looks like it is a Mercedes-Benz rebuild.

Things I thought I knew before working at Greg's shop:
-The timing chain was stretched about 5 degrees using the camshaft notch/tower notch against the crank.
-The IP definitely needs timing.

After the work:
-I have a camshaft with 18 stamped in the back.
-18 is not listed for cam timing specs.
-Against the 2mm valve test, my crankshaft balancer reads 16~17 degrees.
-Cam gear wear is very minimal. Teeth look good. Chain looks good.
-I have what we think is a 2deg offset key installed right now.
-My IP was missing the overflow banjo bolt/drain tube.
-I really should replace my front main seal...

Now, do any of you folks with the super secret Mercedes knowledge have the timing specs on that #18 camshaft?

Thanks all!

Phil Forrest
