Cheers guys. as usual i have made the job harder for myself by stripping the whole unit down so need the full gasket set now ...didnt think i could get to the bolts holding the unit onto the manifold...bet i was wrong tho wish me luck.

....I've got a funny feeling that i might need a look at that in a week or two! :blush:
Just started stripping mine down last night after discovered a hissing sound coming from the back of the unit when i rocked it forward. there seemed to be rather a lot of movement of the unit...is this normal ...
