Trying to remove the head on a 2000 Vectra, with the z22se engine.
Everything is pretty much all done, with the exception of removing the sprockets from the cam, so i can slide the head up and over. You cant lift the head up as the sprocket bolt is in the way. I simply cannot under no amount of force, remove the sprocket bolt.
Without them coming off, the whole job is stopped. I snapped one ratchet already, dented a spanner and slightly rounded the head of one of the bolts (but a spanner and socket will still grip, i stopped before i rounded any more).
Ive hit it, kicked it, smacked it with a hammer, leaned on it, pushed it, pulled it... done everything but eaten it.
Im told its not a left handed thread, can anyone confirm please and any ideas how to get them moving?
