300E Head Bolts
 

I have an older, but in excellent shape 300E (M103 engine I believe it was) with a 3.0L inline 6. Unfortunately the other day after checking my engine oil which I do every other day, I found that my oil level was drastically low. Of course the first thing I checked was my radiator. Sure enough, it was filled with oil. After doing some research, I found that the 103 engine is notorious for head gasket problems with engines 250K miles and above. Which I understand, the engine has a lot of miles, but it has far more life left in the engine than that. I am a decent mechanic, and I'm able to do the repair work myself. However, after removing the exhaust manifold, well, moving it out of the way, as well as in the intake manifold and all, and removing the valve cover, I come to realize the head bolts are nothing more than massive Torx headed bolts. I cannot find anyone that has the size I need. Does anyone know where I might be able to find the proper Torx wrench I need, and what size?

Thanks

Well I believe I found the answer myself. From what various websites say, its a 12MM Allen (55pt) wrench. Which is odd, looks more like a Torx wrench than an Allen wrench to me.
