shouldn't be hard to make the part.
it's just a curved piece of flat metal.
the only 'tricky' part is the springy clip part where it clips to the body
of the sensor.
Something using a hose clamp would work just fine.
about like making a heat shield for a rubber engine mount near an exhaust
pipe in an engine conversion .......
you arrange some way to have sheet metal between what you want to protect,
and what you are protecting it against.
Like on a camping trip say................... an O2 sensor could be made
from a beer can in 10 minutes probably,
about like making one into a candle lantern .......it's just metal, easily
shaped, cut, drilled, bent etc.
reminds me of the head shield on the return main coolant hose on 1.9
waterboxer engines.
People evidently don't enjoy me pointing out the weakness or weird things in
VW's as I see them......
but considering all the engines ever made by all the manufactures on earth
.....
how many of them have a main coolant rubber hose an inch or so from an
exhaust header pipe ? - none of them !!
so VW did what we want to do here - nice little heat shield .
not hard to make, I must say.
fwiw, I don't think having that part on there is so critical - the 02 sensor
shield on a 2.1 waterboxer engine. If I see one missing, I don't sweat it
too much. I always install them of course, but , I have not found any issue
about them getting too cooled by air flow, or wet from running in the rain.
1.9 waterboxer engines don't use one, and they do all right.
I'm also sure they wouldn't have put it on there unless there was a
reason.
If my own van was missing it, I'd put one on though for sure.
I might have a used one for sale. I know I don't have 6 of them laying
around, but I might have one I could sell.
