I have seen this before and have not noticed any adverse effects from it. If I remember correctly, I replaced the tensioner in the first engine in the 300D that was like this. The new tensioner lined up the same way. About the only way, in my opinion, there is to line it up is to shim the lower end of the rail closest to the block. Not exactly sure how you would get the shims in there though. You can drive the car a long time like this.
