Water Thermo Valves

so i've been doing a serious overhaul on my truck... my motor is all apart i just got a reman head last friday, just got my pacesetter... i want to start puttin chit together, but lookin on my intake theres one piece i remember'd i need to figure out. So i was strippin the intake weeks ago, prepin for paint, i pulled out the water thermo valve( as listed on the vacuum dia.) and ended up breaking one of the blue nipples coming off it. so im about to get my weber conversion too, so is the thermo valve needed, i got this quote from mazda forum.

"The 2 vacuum ports coming out of the weber, you don't use both of them. One you plug, the other you run to the thermovalve and then from the thermovalve to the distributor vacuum advance. This is so that the advance doesn't work until the engine warms up. I don't think it really matters that much because distributor has a mechanical advance/governor mechanisim built into it as well. "

so what to do?



thats my intake, the thermo valve goes in the furthest back open port close to where the egr mounts.

this is a pic that i have maybe this will help you out. i have my dizzy ran straight from one of the vacuum ports

by dizzy im guessing you mean distributor advance??? yeah

if thats true, you just plug the thermo valve hole? or just disconnect all the vacuum to it?

so just capping off the egr looks like a cool idea, you went to school to make that? how thick is it? i guess you could copy the shape of the egr itself, the whole pattern, and use what 3/16" aluminum?

i was in school when i made it. its actually two pieces of 1/8" aluminum. used the gasket as a base. cut it out tig welded them together and used a bastard file to shape it along with lots and lots and lots of sanding and polishing. dizzy means distributor. if you need me too ill snap a few pics tomorrow that can help you out.
