Then of course there's the fact there are probably as many BMWs using this part in the world than Chevy made cars yesterday.
If you have a rare talent and are willing to work for a dollar, come on down.
It's not that I don't understand economics.
The idea is to avoid being involved in their economics by letting them keep their fancy package (a ziploc bag with a sticker on it) and their part in Taiwan.
If I have to replace it again, I'm just going to make an adapter (I have access to a lathe) so I can use one of the cheap threaded fittings. I found one good for 180 Celsius for $8 on Amazon.
The adapter would simply be an 8mm thick, 40mm diameter disc with an 0-Ring channel machined around the circumference and a threaded hole through the center. I'd use a tight fitting O-Ring and also silicone it in (with high-temp oil and gas resistant silicone). It wouldn't be a bad idea to put a couple of blind holes for a pin-wrench in it so it could be held while threading in the sight-glass. Making this would take about 20 minutes, and I'd enjoy doing it, so the value of my time is insignificant.
I bet a person could have a local machinist or handyman make this for less than $50. They'd be supporting a local small-business, which is nice.
Anyway, hopefully my new sight glass doesn't leak for many years. I just posted this thread for the benefit of others who might one day seek an alternative.
