As with two others on USMB right now, I'm in the middle of a CCR engine swap as well.

 

If you dont know, on my Brat, its completely without the emissions garbage. Just ran with a carby, dizzy, and block. I stripped all the parts I could do without digging too deep. Now, with the new block, and having to take everything apart anyways, I'm wanting to rid the engine compartment of the remaining eyesores.

 

I've got a template made for an EGR delete plate, going on Monday to have it cut out of 1/4" aluminum plate. I've got plugs for all the little vacuum nipples on the intake, as the only vac line thats required will be for the dizzy, from the ported nipple under the Weber.

 

My question is with the coolant passages within the intake. Right in the center, under the carby mount is a small (1/4"?) hose, that twists around to a film canister size device (thermo-valve of some kind?), that connects to a T that is connected to the outlet side of the water pump...where the coolant flows to the heater core.

 

I just need to know if this small hose is required for anything as far as proper operation of the intake? I'm in a warm climate, so I fail to see what this small bleed hose is used for, as I assume its to give heat to the base of the carb... but I could be wrong like usual. Can I safely remove this hose/thermo-valve thing and plug its nipple on the intake and block off the T fitting on the other end?

 

EA81 gods, what is your answer?

You can plug all those extra coolant passages - they were there to heat the base of the carb. Not really needed in a warm climate.

 

As for the EGR - just whack the valve portion off the cast iron base and weld the actuator pin hole from both ends = instant, free block off plate.
