Most likely it is a failed head gasket.
broken piston rings maybe and oil gettin into the piston chamber.. too much oil maybe a blown head gasket... the smoke is steamy
You need to replace the power steering pump. If it is leaking, it is going out.
Check engine light, poor fuel economy, cuts out, mis fires, stumbles, hesitation, black smoke,
smoke a blunt
my dodge has the same problem, it is the power steering return hose being cracked or cut.
only thing that will cause smoke in steering column,is an electrical short in the wiring inside the steering column
Smoke coming out of steering box usually means the fluid is burned. It can also mean that the steering gear is failing.
Bad bearing? Leak onto engine component?
I also have a 1993 Cadillac DeVille and smoke is coming out of the steering wheel. wish I had an answer.
Power steering line leak, need to fix as can cause fire.
Oil leak? Valve cover gasket? Power steering pump?
