hi guys,

I spend much more time on the 280te 123 resto over the last few years than my 6.9 which is running well.
I made a brief video of the auxiliary air valve which I learnt a little about as I needed to replace mine.

anyway, if of interest see attached

Excellent work!  And that engine is beautiful.  Mine has little drips and seepages no matter what I do.  Just wondering, can these valves be resurrected with a solvent soak or similar treatment to free a sticky piston?  Cheers,

I learnt a little about these things during the process Dave.
some say you can rebuild them, most say not possible. my German mechanic said they weren't rebuildable and he knows a lot more than than my 3 Horus of googling.
there was a bloke selling the heat sensitive bulbs which I understand are the main reason they fail. they were about 80 bucks each.

my car is still not perfect at idle, im wondering what next. ive had the WUR rebuilt already but not the fuel manifold.  reportedly the cold start valve is fine.

before I start paint and interior, I want the mechanicals as good as they can be. after much much financial investment, its getting there.
the underside of the car has already been painted, and many new parts from brakes, to bushings, radiator, and everything has been done!
