Removing 3.9v8 downpipes.

[Markdisco94]

Are there any threads anywhere on how to get the downpipes off a v8 disco1?

I've searched and can't find anything.

Any special tools required, special techniques, things to know etc.

Thanks

There's only one pipe as such which is called because of its shape a Y pipe, so just undo the six nuts (three on each manifold) and if you want to remove the Y pipe completely two nuts joining the pipe to the middle silencer.
No special tools required just spray 'Plusgas' beforehand and new gaskets are required when refitting.
If u have an auto and if it's box has been serviced it may be easy as the Y pipe has to be removed to change the auto box filter.

Thanks Discool.

It is an auto so hopefully previous owners looked after it.

I'll tackle it soon. Might do the box at the same time.

The chassis cross member also has to be removed to be enable the gearbox sump being removed.. So best of luck on that, get someone else to do it
