Oxygen at high altitude on non-turbo 240D

[IndianaJo]

Turbo Owners are excluded, please.
My '80 240D started smoking blue terribly as soon as I entered Carson Natl forest on US 64 west of US 285 in New Mexico, and I pulled up the crest in second gear. The next day on Cumbres Pass on NM-CO 17, I had to pull up to the pass in first gear. I realize I could solve all my problems the next time I go with a turbo. (I've already installed new injectors, and new cylinder liners-rings-pistons are also in stock waiting installation on this cheaply rebuilt engine). But I have thought a cheap solution lies with my 20 CF Oxygen welding bottle, and the needle valve-flowmeter arrangement attached to the argon bottle on my mig welder. I don't need the maintenance hassles or the power of a turbo in Indiana 360 days a year. I think I might get some improvement by putting a rubber hose into the air cleaner from the oxygen bottle, and injecting some oxygen (20 cfm?) up steep hills in the Rockies. Refills are only $7. Any thoughts? anybody done it?
