I recently did a cam belt change on my K series and when I went to tighten the crankshaft pulley bolt it did not tighten properly. I torqued it in stages as I am always cautious in tightening bolts and started at 80Nm, iit clicked so altered the setting to 100Nm but the bolt continued to move for another 1/4 turn with limited resistance. Took out bolt, which seemed OK, but I couldn't see inside the crank to check the state of the threads. Re torqued to 80 and left it (should be 205Nm i yhink). Is it possible to strip such a large thread in steel or am I missing something. Is it safe to run the car with the pulley torqued up at just 80Nm?
