well thanks for all the comments/advice, i have sprayed tons of wd and carb cleaner looking for leaks and no joy. the van is now staying off the road for a bit longer, i am gonna rebuild the engine and start again renewing all engine bits as i am sick of it, especially afeter tonites shananigans!!!! there is no way it is gonna make it to goth tommorow so i will be there in a peogeot partner van with no badge on the front (cos im ashamed) so come say hi if u are there.
I took the van back to garage tonite to check the emmisions on there machine. basically they are just the same as before if not worse. the hiydrocarbons peaked at about 1690 and went up as the revs were raised!!!!!
anyways, on the way home the engine started rattling and knocking!!!! by the time i got to my house it sounded really bad and when i got out and looked there was smoke pouring out the top side vents on the van and from underneath!!!!!
funny thing is, i started it a couple of hours later and it started ok with no knocking or rattling!!!! I am lost with the ruddy thing now and wouldnt trust it now anyway. So as said before, i have a spare engine with it (not sure on condition though) going to strip down the two and rebuild 1 good engine from them hioefully with all new seals ect.
having said that if i could find another engine COMPLETE with carbs and everything still on, so i can just throw it in and get it going/mot'ed for the right price, i may do that (although the other engine will still get rebuilt anyway just so its ready if anything happens)
so as you can tell im not in the best of moods at the mo, although i am passed caring now and think i will laugh instead of cry

going looney here
