For those members here who have a early 500SE/L (or 380 Euro), registered here in the USA, can you do me a favor:

Advise if you have an EGR tube on the driver's side of the motor, and if so, is it routed to the back of the intake manifold? If not, I'd like photos of how it is set up on these engines. (117.961).

Have a .961 motor missing one of these, and I'm interested in knowing how other early w126 V8 cars had EGR set up.

MANY thanks!

This is a normal EGR setup:

The earlier '79-'81's should have the .961 motor.

I believe the .963's came in late '81.

.961's have a bit lower compression ratio yet are considered a bit more 'rorty'.

My 84 380 euro has this exact setup, yes it is on the drivers side, and it is routed on the back of the intake manifold.

My 86 SEC has something like you say. The EGR is on the drivers side of the car, and the pipe disappears somewhere behind the engine block. I want to remove it for cleaning, but I am afraid I'll have to take half the engine apart.
I'd make you a pic, but I can't even see where it goes, let alone get a camera in.

The pic in the EPC is the same for post 85 Euro and pre 85 USA

My 84 euro SEC had it until I had to transplant a motor from a 500SE into it. That one didn'thave it, so I left it out. (Along with a few other bits butchered onto the engine when it was not just federalized but also californicated.)

The 116.961 and 117.961 never was equipped with EGR from factory. In any modifications, countries specifications, etc.
The 116.963 and 117.963 (were made after 10.1981) was equipped with EGR.

Salut! :)

Ok now that has been established.

I do NOT want to transplant EGR on the new .961 engine via the inner manifold.

So my idea here is:

Pipe in the egr from the tri-y into the air filter housing keeping as stock looking and inconspicuous as possible, into the area behind the intake opening.

That way it'll let exhaust gases in and pass the functional check and be easily removable when smog passes.

Are they really that anal about your cars being 'factory' spec?
I thought our MoT test was strict, but by the sound of it, it makes us here in the uk look like we get away with murder...lol
