HELP! freezing to death!

[giterboosted]

Ok so here is my problem, my heater coolant valve isn't getting proper vaccume, it is getting some just not enough, if I put the line that goes from charcoal can to brittle body to the top of the dome it opens just fine no problem, if I simply suck on the vaccume line it opens just fine, but when all is connected correctly it simply doesn't have enough vaccume to open it,

Two questions

1: what's a plausible temporary solution for the winter?

And 2: how can I actually FIX this? Would my egr have something to do with this? Because the vaccume lines seem to hav somehing to do with it


I'm begging you help....

 

[dumbo]

Take the vacum line that is coming from the manifold and goes to the solenoid valve and just stick it on the valve...if that makes sense. Bypass the solenoid on the heater control valve.

 

[giterboosted]

I did that and it simply wasn't enough vaccume

would it hurt anything to temporarily tee off of the line coming from my charcoal canister straight to the diaphragm? Would it hurt anything if i wanted to turn off my heat? I'm seriously thinking it's the big circular thing that's below the small circular disc at he rear of the intake mani with two vac lines on one side and one out the other and a big one out the bottom in the egr system, I know that description sucks but it's late I'm wore out and don't know what to do

 

[hvyman]

no that vacuum off the cc has gas vapors and goes into the engine as part of the stock tccs afr mixture.

when the bypassing the solinoid does not work you have 2 options: a) zip tie the lever in the up position or b) get a new valve or a good working one(as new ones are expensive)

Trace the line that goes to the solenoid, sounds like it's either clogged or got a leak in it.

also try taking the valve off and cleaning/replacing it, years of gunk might have it gummed up.

I safety wired my valve in the open position, but try bypassing the vsv, I did that because mine had a torn diaphragm and would not hold vacuum.

#1:

#2 Have you checked actual inhg at the end of the line? See if it is lower then it should be?
#2.1 Trace ALL vac lines and replace crack/brittle lines. You might have a vac leak in one of them.
#2.2 Check the the "inline check valve" on the vac line for the VSV.

If everything check outs then your valve/VSV is bad. Im guessing 2.1 is your problem, since there is very little vac coming out of the nipples on the TB that you hooked it up to.

so almost al my lines on the engine are new, did tht recently, and there is a substantially better vaccume on the line from the char can than te other two beside itinerary the throttle body, and I know it will hold vaccume because if you simply suck on the other end of the line to the diaphragm then it opens fine, cap it with your thumb and you're set, I may try today the one from my turbo car but I still feel like it's a vac issue somewhere but I can't find it

^^^ OMG!!! Insert; punctuation, spell check, sentences and paragraphs.

:1zhelp: <--- Click me.

Will re-read when it is readable.

 

[mdr40z]

you can test for vacuum, vac gauges are very cheap

 

[giterboosted]

For the spelling punctuation and whatnot ppl, I'm working from a phone as my laptop is down for a while, I'm guna completely finish replacing the vac lines under my hoo today to see if it helps

 

[giterboosted]

also I have one of my old boost guages to use as a vac guage, I'll report back soon

I safety wired my valve in the open position, but try bypassing the vsv, I did that because mine had a torn diaphragm and would not hold vacuum.

this times 10, i took some chicken wire and wrapped it around the control. presto! i got me some nice heated interior...but driving that psychotic thing in a minnesota snow is scary .

 

[giterboosted]

How much vac is it supposed to have at normal, just cranked up idle? Cus I don't have almost any, ten I rev a few times and it moves the lil diaphragm arm half way then rev a lil harder an it moves all the way and stays, idk WTF is up but at least I have heat now

 

[hvyman]

you have a vacuum leak or blockage. you should see about -17-18in-hg

 

[giterboosted]

All my hoses are new and clear, where should I check for a blockage?

 

[dumbo]

You may have engine trouble if you don't have a good vacum at idle. I also gotta agree with 92nsx, write better to get more educated responses.

Your vacum lines should look like this.

This nipple comes directly off the rear of the manifold.

If you have good vacum at your chacoal canister and only some at the heater valve, like everyone else said, more then likely a cracked line or a blockage. Even though a blockage would still eventually pull the same vacum it would just take longer to get there.

So you saying the little nipple (87293E) in the second picture doesn't pull much vacum if you the pull the line (88690C) off? If so you got other problems.

 

[giterboosted]

Wow someone ha royally screwed up my lines, there's a tee coming from that nipple and the line supplying my vac for my heater valve is coming somewere else, but could someone tell me where to find te correct picture for an NA

I just realized my lines are not messed up so bad, only a little bit, they shouldn't look the same as that since it's na

Problem solved guys, thanks for all the help! And sorry for all the bad typing
