Ok, so i noticed this lil guy had both its vacuum lines snapped off. not sure what it is tho. It sits next to the upper rad hose outlet (thermo housing). what is it and whats it do? anyone?

 

Im not sure what they are, but I clipped mine of yesterday

I want to say I traced them back to a solenoid or something on the passenger side fender, and then to a charcoal canister though, so probably not important for actual operation.

 

yea she seems to run fine but idk, would like to replace it

 

I just put vacuum caps over the ends, I am led to believe all the engine really needs is the vacuum advance line to the distributor, the rest is mostly emissions control stuff.

I stripped out all of the vac lines on the passenger side of the bay yesterday but I left alone the rats nest of hoses on the side and back of the carb, I got confused tracking hard lines to vac lines then back to hard lines, I need to take a picture but there was a sort of C shaped length of hard line on the carb base that was nothing but an elbow I guess to hook the vac line around, it didnt make much sense to me.

If I can find a camera I'll take some pics of it.

Just dont disconnect the brake booster and you should be safe if not good at least lol but if you wanted to get rid of that too, you could go hydroboost out of an astrovan.

 

that would be sweet dude Im gonna be taking out the stock exhaust manifold today, looks like it has some smog crap on it tho and the O2 sensor... im not sure what to do with the header doesnt have adapter for it ill check around the forums for a work around if you know of any u can link id appreciate thanks for the help!

 

Those are valves of somesort. Eiher check valves or some a regulator thing for the vaccumm. I belive they are all for emmissions purposes

 

i appreciate the help fellas. So final word, dont worry about it then? i mean ill cap em and secure em i guess. got a question about the exhaust manifold too, but ill start a new thread for it
