My 1980 240D "What's This?" thread

[graydonblair]

Ok, lots of questions. Here goes:
I have a 1980 240D I just picked up & it looks like it might have some frankenstein parts under the hood (newer motor? EGR?)

I'll post pics w/ questions:
1) Under the hood:

Just giving a starting point.

2) If this is a 1980, I understand it's not supposed to have an EGR.
Is this an EGR?



If it is, it's definitely unhooked & vacuum lines plugged

3) What's this thing (just in front of the air cleaner, circular thing)?

It appears to hook up to the EGR. It has what looks like an oil return line going down to the crankcase (which is leaking--not bad, but it's an oily mess down there)

4) What's this thing? (just to the right of the temperature sensor?)



5) What's this thing? (black canister mounted to F/R fender).

Has a vacuum line (unhooked) and has a throttle cable that goes out of it up to the throttle. Also some electronics look to come out of it and some other things. Reminds me of a cruise control on my 85 300SD but there's no cruise control inside the car.

I'll post more pictures as I have questions about things on this car.
(ps if the pictures are too big, let me know & I'll size them down)

Thanks ahead of time!
