Thanks guys, got it all sorted, tightened a few hose clamps and cleaned up the pipes, seemed to have the leak throught the hoses. As for the turbo fittings, ill probably be getting that sorted sometime next week. On another note though, I pulled off the piping from the turbo off, to fit a "dose pipe" but got over it pretty quickly and fitted it all back to standard. Whilst doing this I also pulled off the pipe from under the battery, to get easier access, and refitted it also. Now its all back to normal, until I drove it for a couple hundred K's, gave it a squirt and somethings popped off.. SO I check all the pipess!!! over again took em all off and made sure there was no gaps and everything was tight.. But I think I have a huge boost leak somewhere. When the turbo kicks in its almost like the BOV is open like all the time!! I can hear it loud, but its not like spool sound its like the BOV opening sound. I also had flutter normally with the standard pipes, but since this I just hear a massive whoosh, and no flutter. Is this possibly wastegate related? something fallen off? Any ideas wherelse I can check, Im 100% sure there no leak from the cross over pipe, or the under battery \pipe or the turbo to crossover pipe. THanks
