First of all, thank you all for the awesome support and advice given to me the past two years owning my Benz.

It's still ticking!

And on a related note, it's going to be ticking a lot more here soon.
I got myself a nice job at a big school district in the Seattle area. I figured my car is in good enough shape that I can run it for a little while on the 50 mile round-trip (freeway) journey every day. BUT....there are a few issues that I want to look at and hopefully resolve soon. Actually, just one major issue at this moment. Has to do with the awesome problem of oil leaks.

The oil filter housing is leaking progressively worse at the gasket. I saw this a while a ago and thought it'd be an easy enough fix. Save myself trouble down the road by doing it now. So I go and buy an OEM gasket from the dealer and I'm set to replace it and refresh the housing a bit....
...or not.

I go to remove the allen bolt that sites right next to the steering box, and it turns out it is rounded out! Guess a PO or shop did this...grr, and it had to be THIS bolt out of all of them! Thanks, Murphy....
So, gents, what would be the best way to remove this stubborn thing?

I've heard of tapping it out, getting a set of vice-grips locked onto it, hammering in a larger allen screw or even a Torx head into it....the real issue is space. Not a lot to work with here next to the steering box. And if anyone has a few of these bolts laying around, I could really use extras! If not...to the junkyard I go.
