...not all the way out, but the injector clamping bolt's head has come off, and the the 25mm of exposed bolt remaining seems very tight. At the side of the road we got a reasonable purchase on it with mole grips, but the bolt would not budge.
The van is a Renault Trafic long wheelbase, all four injectors were changed by a garage about 6 months ago. It's now languishing in a garage compound in Germany, having been towed-in. The garage are just about refusing to do the job, so one option is to go over there and a) recover its contents of tools, clothes, beer and wine, and b) try to remove the broken bolt, resecure the injector with a new clamp bolt, and drive it home.
My questions are:
1. What is the normal tightening torque of the clamp bolt? It has (had!) a 10mm A/F head.
2. Assuming this to have happened to others before, what's a good method to remove the remains of the bolt? It HAS NOT seized in the head as we found that the shaft can be moved a mm or so at its top end - but it won't turn!
3. What are the best tools for gripping this exposed bolt shaft?
4. The bolt seems very hard, and is resistant to cutting and filing.
