Hello, I´m repairing my gt´69. The motor was opened 3 times at least. About the timing tensioners i´ll mount the new rubber kit although the original are those made of metal-plastic, i think here there are no problem. But about the head screws, perhaps mine are used for tree times, i don´t want to use them again. I can´t find anywere a kit with 10.9 quality, only 8.8 or 12.9. 5 u - M12x1.50 60mm, 10.9 5 u - M12x1.50 90mm, 10.9 I thing that ZXN or Allen is no important. I would need tight them until 100Nm, the 8.8 according usually table allows as much at normal uses 92Nm as much,...in a motor head...¿?. The 12.9 quality could be too much rigid to accompany the head at it´s dilatation? What can i do, what are my mistakes? Thanks. Regards. Jaime |

Hola Jaime, They also have the timing tensioners Timing tensioners For the screws - most hexagon screws are extension screws ment for one time assembly only. Your old ones are usaly "vielzahn" screws and can be used more than once. Gruß Stephan Hompage: http://sh.opelGT.org Mailto: Stephan@opelGT.org |

Hallo GT Community, Thank you, Tom. I´ll keep this adress!, i did know it. Stephan: it is a great news for me. My old screws really looks like pretty. A screw when is overthightened advice, i belive that if i use a tube long enought to make me feel its behaviour. But around the head cam is a lot ghosts and myths, and don´t want to play with my "babe". And my arm is not a precission machine The last time that i tight those screws i felt them truly solid. I´ll fit them again.  Thanks a lot Jaime |
