Those things MB will replace for free with the catalyst pipe. Check it out, you can get a free exhaust system and turbo out of the deal if you're lucky.

WOW you got a 51 Caddy? I worked on one of those things back in the early 80's, a 51 Fleetwood. Had power window problems. Gotta love it, hydraulic power windows and power seats. What a great car though. Love the hidden gas cap, very clever.
