83' 302 EGR Delete

May 12, 2015, 12:38:42 AM

I've just been away from the mechanical side of things more than I'd like lately! ( 80 hr work weeks. Fun stealers.)

Doing a EGR Delete on an 83' with the CFI 302. Smog pump is already gone from a long time ago - not an issue.

On the back of the CFI Throttle Body there is a long oval shaped device between the EGR Valve and the throttle body itself. - Coolant from a heater hose flows into 1 end of this oval device, and out the other side of it into the intake manifold - via hoses.

What is the long oval shaped device? ( I'd imagine its related to assist in starting in cold weather, but would appreciate any other info.) - This car is put away inside November - March most every year.

Can this oval piece be removed? If so - whats the best way to handle the smaller coolant hoses on it?

Appreciate the help! Thanks!

Coolant is pumped through to regulate temperature of the intake and cool the exhaust gasses being pumped it.

The egr looks the same as the ones on later model fuel injected models. Most people fabricate a block plate and either loop the coolant lines together or remove them and add nipple plugs with a hose clamp.

Supposedly you will lose mpg by deleting it, but on my cars, o didn't notice a difference in mpg or emissions.
