Removing the smog stuff

Hey Guys!

Tomorrow I plan on removing the rest of my Smog Equipment, from my

'76.

One question that comes to mind though is.. "Does the EGR Vale just

come right off, or am I gonna' be needing to block a hole that it's

covering or something?"

I'm led to believe that there's a hole hidden underneath it.

"Is that the case?"

If so, what do you guys use / do to cover it?

Thanks,

Ken

But I think it's threaded for pipe and a plug will fit. YMMV. I took the '76 manifold off in favor of a peanut manifold - which I then hogged out for a Weber 38. But the '76 has a simple threaded hole for EGR, the pnut was off a '73 and I had to fabricate a block-off plate. Cut a piece of sheet metal from an old "no parking" sign, ddrilled for the mounting holes left from the egr fittin, sealed with hi temp rtv, along with using 4 machine screws. Seems to work well, I'm pulling 19-20" vacuum.

no thermal reactor. There is an air pump and a "gulper valve." With big pipe to exhaust manifold leading to air injection at the exhaust valve. EGR puts exhaust into the intake. I couldn't even find the fitting on the exhaust manifold where the exhaust gasses are picked up tobe recirculated but I think you're probably right about the hardware store fitting.

CA cars have more "stuff," different exhaust manifold and I think they use the thermal reaction system all the '75s did.

OK... I guess I may of missed something here. 'My bad." The piece I'm

reffering to, is a Black Plastic(?) piece that sits on the opposite side of

the Exhaust Manifold. That is.. "It's not on the same side of the EM?" It's

resides on the Intake side. Actually.. come to think of it... there's a

hose coming from this "Black" piece that goes directly into the Air

Pump. That's the piece that I wan to remove. The EM I'm using is the

EM off a Tii. So, in that case, I'm fairly certain that I don't need to plug

anything on it. It's this "Black" piece I'm not sure about. I do think it's

some-sort of Valve though.

Sorry for the confusion. "Any idears as to what this piece is?"

.. and "It is a California car."

Thanks,

Ken

It was done by one of the Sacramento guys. That's a BMW logo on the manifold where the EGR input used to be. Quite cute!

Dang, thanks for posting these diagrams. The originator of this thread must have a CA car, which must be the top diagram. Because my 49 stater does not have the EGR stuff, and the diagram confirms there's no EGR stuff on the 49 state model.

Plus, and this is the part that I like - I didn't realize that there's a check valve on the air injection system. That means I can ditch the hose and plug I put on when I disconnected the air pump! That'll clean up the engine compartment some.

Where did these diagrams come from? I didn't find them in the copied BMW maintenance guide I got.
