A short day yesterday at work so thought as I now had all the parts I'd rebuild the manifold. Got everything bolted on and then noticed the new crankcase vent hose had unclipped so left it for last night to start afresh from work today. Realised I had to take the whole lot back off to gain access. Did that bolted everything down stuck all the air intake back on all I needed to do was connect the F type fitting into the air intake pipe and SNAP! The engine block breather pipe (sucking jet pump) decided to snap leaving the whole lot to be dismantled again. At that point every tool was dropped bonnet shut and decided that rather than hit it with a massive sledge hammer I would come indoors. I think that is it now have no interest in spending anymore and will be cutting my losses and breaking it for parts in a few months. Wish I had listened to the missus and that is a first!
