this happened on mine, come to think of it, you did it! i cut through the offending bolt with a dremel, and it came free then. only top top part of the head of the bolt snaps off, leaving the wider part holding the head down | |

Yes i agree, cylinder head should come off if the head of the bolt has snapped? Also id the head of the bolt has snapped that should relieve the tension making it quite easy to get the bolt out by welding a nut on. | |

i'm lost. the head has come off the bolt, but the cylinder head head wont come off? surely the headbolt without the head, would be just like a metal stud? so the cylinderhead should come off.... | |

tried that before, doubt it would hold as they were rediculously tight. | |

well, the head is stuck on because only the top 3-4mm sheared off the bolt. | |
