1986 1st Supra Running Poorly

dlfred · 03-17-2010, 02:01 AM

This is the BVSV, it has nothing connected to it? Does it need this in the loop to run correctly?

Yeah, run the charcoal canister's purge to the BVSV and from there to the TB. It's a flow control which prevents the charcoal canister fro providing extra fuel when the engine is below a certain temp.

The BSVS has one of the nipples broken off. Is there a fix or just get another?

Nice info link at the bottom of your last post CRE.

Thanks folks

The BVSV's are very expensive new and I don't know of an aftermarket solution. The best bet is to hit up a salvage yard and grab a couple off any Toyota's of a similar vintage. Most will fit and operate at a similar temp.

Thanks, I really need to update some things and add a couple new wiring diagrams, but you know how it goes... other priorities and all that.

Have everything out of the way and was able to plug in the KS. Now I have to be able to check the vacuum line routing and connections. I guess I can understand the lack of clean up for a flat rate mech, but man it sure was nasty in there. What causes that much intake goo? It looked like mud/grease all though the intake plenum and box. It is now much cleaner.
There is a small 2 hole bracket with vacuum line hook ups, on the drivers side below the intake. Any ideas on what those 2 bolt holes line up too? This thing has been good to work on so far. Thanks

There is a broken wire on one of the connectors, VSV I think the filter is broke of it and now there isn't a bit of wire to repair the connector.

As far as the broken wire, I was thinking that I could take a straight pin and connected the wire and connector using the pin in the center and solder the area. Sounds pretty cheap, I haven't figured out how to push the remaining wire out of the connector and go at it that way. I am open to suggestions, please.

thanks
