FDV weep

Before embarking on the overhaul of my GTi auto (welding first, then head off, front brakes etc) I want to know if the is a way - as much as possible 'once and for all' - of fixing the slight drip either by repair or replacement. It's not a job I can do but would ask someone to do it for me... I just need to be able to plan this 'restoration'...

FDV's can be overhauled - which is really a dismantling and replacing of the seals. Its not an easy job and mine didn't work properly when I did it.

If you look at the thing - there are 5? caps on oit. 4 are plain and the kit contains new 'O' rings for these. The 5th one (middle of the side with 3 ports) is an adjuster and can be unscrewed easily and if its leaking the O ring seal on it can be replaced.

Finally there are the pipes - which can leak at their junctions if stressed (ie doesn't go in quite straight) (or simply loose - not as daft as it sounds - they're difficult to get at and not meant to be done up very tight - so its easy to think you've tightened it enough and for it to work loose later)

Tightening the pipes (gently) has cured the FDV weep for myself and I think two others on the forum.

Me too on both of our BX's. A slight tweak on the nut often does the job

It works for me

I'll see what can be done...

But at the moment I've got to get a quote for the boot floor welding. Looks a straightforward job so don't expect it to be much. But then again

Do check the plugs on the side of the unit for weep. If it's leaking there, all the pipe-tightening in the world won't do any good.
