E70 tensioner bolt hole broken(pics added)

[WaterMonkey]

Good day to everyone.

I recently purchased a 09 X5 xDrive 3.0

Was told the belt had slipped and the tensioner had bent. And someone tried to fix it and stripped the bolt. Hearing this, I purchased it anyhow.

Upon further checking by removing parts I found that the belt tensioner bolt hole is broken.

So I need all the ideas in the world. Any bypass, workarounds ideas anything.

List of things I have checked.(please double check)

1.) Internet search, everything I found is belt tensioner bolt holes broken but usually are part of alternator or engine timing cover. Neither of which apply to the n52k(n52b30), not as far as I'm aware.

2.) Exploded diagrams of engine block. I was hoping I could remove the cylinder head and remove the "disk" that has the hole from the engine block and install a new one. I don't own any paid website diagrams so maybe it's one of those parts.

3.) Stretch belt , but none of them I found are long enough (around 48inchs) .

Here are some pics.
