ahh well a new day, hopefully i can get it all going again today.
thanks for the help , i iwll update in a whiule.
after having a good read about the amel valve, it sounds exactly like the symptons i was first getting before touching the aux pulley timing, when the boost came in it missed and popped.
what would be damaged by running with a pipe not connected to the amel valve.
there seems a lot of things that could go wrong with these engines, am i right lol??
but i can see where the addiction comes from, im having a pain with a cossie but im finding myself wanting and longing for one more and more lol.

thanks andy
