I am just trying to understand whether there are different turbos on models of the car; reading the Haynes manual, they seem to list 3 variants: XUD9TF - turbo XUD9SD - light pressure turbo XUD9 BTF - turbo for catalyst Not knowing how the variants were marketed back in the day, I wonder why & what the difference is between TF and SD types? (I guess the BTF came along a bit later, when catylsts became mandatory). Q. If I had the SD type, could I fit TF, in order to get a performance boost? If so, is it a simple spanner job? All guidance will be appreciated!

Managed to get help from a local mechanic - we found another nut, at base of manifold, but then had quite a job getting enough clearance for removal of loosened manifold. Had to loosen the actual turbo, to allow clearance of manifold to (I think) pop-off valve. Any way, job now done, and my thanks for all advice given - not easy! (PS. Wonder what the actual tubo is, in terms of manufacturer, model, spec? Is it a 'low pressure' turbo, as used on some PSA variants? )

Ah, that sounds quite possible - can't just get a good visual, despite use of torch & mirror, darn it!

Oh, 1.9TD engine. I'm now wondering if there is a SEVENTH fastening to the manifold - I took off 6 nuts from conventional studs but now see that Haynes manual referes to a hex-head seventh one, in the centre of the middle pair of inlet tubes. Anybody know anything about this?

Hum, I'm rather stumped - I have undone 6 nuts from manifold, which is now somewhat loose (wobbles by hand, small gap visible between head/manifold) but it doesn't want to come any further. I've tapped it at ends & centre of top chamber but don't want to go mad on this, in case the casting breaks - what could be holding it from coming off? Any ideas, please?
