I hope someone can offer some advice on this one I'm working on a Zafira with a Z18Xer in it, it was leaking oil all around the rocker cover, on removing it the usual 2 bolts snapped off in the solenoid housing (happend before on my astra) got the cover off using a Dremel and cutting the plastic off round the bolts and gave it a good clean up got the mole grips on the first one and it just snapped the casting off without any force at all. So my question is can I replace the solenoid housing and get away with it or is the head scrap now
