Trap Oxidizer?
Trap Oxidizer?

09-11-2009, 08:10 PM #1I viewed a video on youtube about a recall on the 300sdl. I recently purchased an '86 300SDL. The recall had to do with a "Trap Oxidizer" and exhaust system. I dont know what a trap oxidizer does to the engine but have read that the EPA will replace it free. Does anyone know anything about this recall? Is this the reason why my exhaust is so clean?

Quote:Is this the reason why my exhaust is so clean?Yes. The TrapOx is a particulate filter, the same thing new diesel engines are getting, except a much older design that uses passive regeneration (engine heat made during normal operation) instead of active regenration (a computer makes the exhaust hot by injecting extra fuel) to burn off the soot.
If you have the football, I suggest you get the pipe off an engine that has already had the recall performed.

After the exhaust, the next upgrade you should look into is getting a W140 300SD/350SD exhaust manifold. Its a normal design that goes straight to the turbo instead of that bypass BS. Quicker spoolup and less energy lost to heating the air.

The recall has already been done. They removed the trapox, installed a bypass pipe and installed a new exhaust system that has an updated OxCat under the passenger floor. Replacing the exhaust will eliminate it.

Thanks alot everyone for clearing that one up for me. Does anyone need an exhaust system for an SDL cause its goin out the door.
