OM617 timing chain stretch results.

[KAdams4458]

I checked my timing chain stretch this morning, and I'm a little perplexed by my findings.

I could not use a dial gauge, since the camshaft is so screwed up, but I wanted some idea as to the condition if the timing chain before I need to place a parts order. I used the marks on the thrust washer and cam instead.

With the marks aligned perfectly, like so...


I end up seeing this at the crank...


I'd call that 1.5 degrees, so I guess there must be an offset key in place already, since this does not look like a new chain at all...


What are your thoughts? I honestly expected it to be all FUBAR. I never expected this, and I can't comprehend why anyone would go to such lengths to correct cam timing, yet leave a scored and flattened camshaft in there.
