Begging your pardon, Brian, your copper disk fit perfectly in the EGR outlet of the trap cat on my '85 300D-T (California version).

Thanks Jeremy.

I've therefore got conflicting info regarding the CA vehicles. Some have the same interface as the Federal vehicles as shown in your photos, and some do not.

Oh well...........it's touch and go with those vehicles with regard to function.

I wonder if the "trap oxidizer" (which had to be changed every 30,000 miles) was externally different from the "trap catalyst?" My car has the "catalyst;" I've never seen the older "oxidizer."

What are the identifying numbers on your catalyst? I am trying to determine if my 'football' has been swapped yet. The car is new to me and I can't tell which one it is (1985).

I'm getting ready to pull mine and will be able to read the numbers, if any, at that time. I will post them here.

Go to a dealership and ask them to look up the recall records.

I believe it has been replaced w/ the catalyst. Dealership confirms "no outstanding recalls" with one completed.

Here are the numbers on my trapox / cat / football: 126-490-34-14.. this also confirmed by another post where another member posted these numbers.

Thank you all. now how the he^& do I get it out of there?

I machined a plug in my lathe that fit in the manifold hole , but also had a small lip and put the stock clamp back on ...it looks reaally clean .
I also machined up a plate to cover the EGR ...that looks good too .
I will post some picks when I have a chance .

I had the exhaust manifold hole threaded for a pipe cap.
Brian's plate looks clean on the intake.
The only possible improvement might be a Mercedes logo on the plate.

Interesting process...
I was wondering if a couple of these disks and an extra clamp would work to simply block the exhaust gases with out removing the EGR on a 98 E300D??...

Thank you for your time...

I don't see why not. One disc over the exhaust manifold hole would do, but you don't get the benefit of a cleaner under-hood environment.

My EGR is under the intake manifold and out of sight... I would consider removing it how ever the newer cars sense when the EGR does not actuate so just leaving it in place and blocking the exhaust outlet and EGR inlet seems to be the simplest solution....
Hoping someone familiar with the newer cars would be able to confirm or provide a better solution...

thanks...

You can't block the EGR on a computer controlled engine without causing a code. The engine then dumps all boost and the vehicle won't perform.

Some folks have successfully plumbed filtered air to the EGR valve..........the system doesn't know the difference between exhaust gas and filtered air.

Aha...
Does that air supply have to be pressurized?? I'm assuming clamping a filter to inlet wont do the job, that the air needs to come from the turbo outlet....
I cleaned my intake last week and it is like driving a different car, efficient and powerful...
I would rather not have to do that job again.. .

Thanks for the info...
