Ok so here is my next question.  Ive replaced that annoying leaking head plug.  Put everything back together.  All except the L125 bolt.  I noticed when I took it out it had what at the time I thought was grey gasket stuck to it.........nope it is aluminum inside the threads.  Whoever had it apart last must have over torqued the thing and stripped the threads inside the head.  The little thin aluminum threads screwed off the bolt slick as anything and now the bolt just spins in its hole.  So where to from here?  My first thought is tap to the next size up and replace the bolt also next size up?  Will this work or am i asking for trouble for any reason?  Thanks guys.
