1987 300SDL

I removed the timing chain tensioner today to fix a pretty good oil leak. First off, I vaguely remember there being a copper crush washer being used as a seal. Is this correct? Dealership put a new head on the car awhile back, could it be possible this washer didn't get replaced?

On to the bigger issue...

It doesn't seem like the tensioner slide will retract far enough to allow the tensioner to fully get screwed in. The tensioner piston gets pretty hard to turn, then becomes impossible to turn without force when it has about another 1/2 inch or so to go. I took the tensioner back out and it compresses as it should. No issues there. I can't think of a way to make that slide move in farther.

What the heck......
