The original Trap Oxidiser is a big barrel shaped assembly as shown in the photos. The replacement catalyst (if that's what it is) on my SDL with the 603 engine, is a much smaller diameter cast pipe with some bonded silver heat shielding around it.

I have a 85 300TD wagon CA. The trap oxidizer work was done - along with a new turbo. The kargr "football" looks like the original. But there is a sticker in the drivers door - says "NON CATALYST",(since I am not the original owner) I am not sure if this was always there - or if it was put on after this work. Question - is there a "football" shaped item that is called "NON CATALYST"? Is there any way of removing this can - while using the same turbo - (It may seem unrealistic) - but I would like to use this turbo - it is new.

Thanks

Steve

I swapped all my components from an '81 300SD. I could not use my original turbo. I tried to spin the housing but the oil return tube would not line up.

I just had my trap oxidizer go bad in my 124 back in December. When it went, it took out the turbo. We were leaving to go home for Christmas when it let go. It took out my turbo when all of this happened. I took it to the dealership and they replaced the entire exhaust system to include the turbo and muffler and everything in between, at no cost to me. They had the car for about a month because some of the parts had to come from Germany. They gave me a loaner to drive while I waited...they gave me a 2005 C240.

The catalyst retrofit on the 617 engine ('85) looks exactly like the oxidizer it replaces. The only way to be sure you have the newer trap is to take your registration into a dealer and have the service manager look it up on MB Net. MBZ kept records of all warranty/retrofit work done by VIN number. On the 603 engine the football shaped can is replaced with a foil wrapped pipe shaped trap so the conversion is obvious, if it has been done.

Last January we called MBUSA about the trap oxidizer in the 85. The car is a Kalifornia car. MB said they did all the update work on the car. Last week we pulled the head off to install new valve guides and I took a good look at the thing. No insullating foil, football shaped, and not a thing inside of it. It is just an in and out for the exhaust. Any comments on what we found with ours will be appreciated.

Thanks all

JRB,

Did you look into opening where emmissions valve hooks up? Can you see it through there?

Steve

I just made a quick trip back to the shop and double checked. Inside where the emmissions valve hooks up is nothing but a pipe with kind of a baffle/exhaust deflector welded on. I checked with a flexible flashlight. It's empty. What do you guys think? Tomorrow she goes back together.

I had mine replaced back in '97. Its leaking now. Just went to a shop today. They told me its a $1000 part. Anyone ever fabricated a replacement? Thinking of bringing it across the border to get it done. Any suggestions?

Some have gone to Junk yard and got Manifold,Air Cleaner, Turbo drain and new gaskets, plus the firt section of Exhaust pipe. And toke the trap off and replace it. Off of a 84 model.
Also removed EGR valve.
Now this does not comply with some smog laws.
But the law of nature is cleaner for it.

Here's a picture of this trap oxidizer I removed tonight. Big ol' pain in the butt to remove for SURE.
