Kingcon, I dont think it has set off any codes, as there have been codes for other things like my camshaft sensors. Like you have expereinced I too think it will run smoother once the pipes are done.

Amacman, do you know where these write-ups are on the forum? I've already run a search or two containing the words 'hoses, oil, and breather', but nothing comes up. Do you know where there could be any info concerning the removal of the bulkhead? It looks like a few bolts here and there on the front but I'm reluctant to start undoing things incase I have to start pulling the car apart, and then the dark catches up with me, and I have half a car left!!

Thanks for any info you can supply...
