Per post yesterday, I’m strongly considering selling after 24 years, which I guess would make this “someone else’s problem”. 
But in the meanwhile, looking at my options.
1967 DGS with A/C in Western WA. The Thermactor pump just starting making a rhythmic scraping noise, which I’m assuming is a vain scraping on the housing interior. That doesn’t feel like a sustainable situation for long.
[Side question: if anyone has as idea how long I could safely drive like this, LMK. Am I in danger of completely seizing up the next time I go out, or will I likely have a little while of somewhat-noisy experience?]
As far I can tell, my options are:
- Remove the engine belt. Cheap “solution”, although the A/C would no longer function
- Remove the thermactor and associated equipment, plug the intake vacuum port and injector ports in the heads. Also relatively cheap, but to get the A/C to work, I’d need to locate the correct a/c adjustable idler pulley, which appears pretty difficult.
- [not sure if this is an option or not] Disassemble the pump, remove the interior, reassemble the housing, and reinstall. As long as the bearings are good, would that work? Slightly worse emissions, I expect, but the thermactor system didn’t work all that well in practice anyway.
- Rebuild the thermactor pump. I don’t see anyone who rebuilds these 1966-1967 3-vain designs; perhaps you know of someone? However, I expect that, if I did, it would be the most expense option.
Thoughts welcome and appreciated.
