Recirculating BOV

[eric91gst]

i know i know, somebody has proly alreay answered this question but i couldnt find it after searching for a long time. i recently bought my 91 gst. it has a bov vented to teh atmosphere and it takes forever to start up cold, sometimes stalls, and doesnt seem liek it running liek it should. this is why i wan to reroute my bov. but since my car already came vented how do u reroute your bov back to teh turbo. i ahve that loud turbo xs bov and i dont think u can use that to reroute. if there is a how to, on this site to do that please link me, or somebody just answer my question.
-thanks a lot

Which Turbo XS blow off valve do you have? Some of them can be recirculated and some can't. I'm not trying to be an ass but try to use proper spelling and grammar, it makes it a lot easier to understand what you're saying and it will keep you out of trouble with the moderators.

Well, if your intake has a port for recirc and it's not plugged, that's why you're having so many problems. Get a 1G for cheap, or if you have some money, a Greddy Type-S or similar, and recirc it. I don't know anything about the TurboXS, so no advice there.

if by the loud one you mean the RFL - i think the "horn" is threaded.
You can unscrew the horn and screw in a piece of pipe and hook it up that way.

Are you venting with the stock MAS or are you just kidding? I hope do god you're joking

TSI User is right, just to clarify it doesn't make a difference what kind of blow off valve you have, if you are still using the stock mass air sensor (1g or 2g) you will need to recirculate your bov, unless you like your car to run like shit. The only way you can properly vent your bov without adverse side affects is using a gm maf in blow thru configuration or by standalone. This is probably the most asked question on these forums so please search.

eric91gst are you still on the stock intake? If so you can get some tubing and plumb your bov back into the hole that comes up just right before the turbo. If you don't have this hole you will need a new intake probably or have to modify the one you have now.

Here is a link how to instal a GM MAFT http://www.dsmtuners.com/forums/showthread.php?t=99455 , just in case you deside to go along with that upgrade path. Or just custom make tubing to recirculate the BOV to the intake pipe if it has the tube on it, or if its not plugged.

u need to run a hose from the bov to your intake hose. i guess that answers your question.. just take of your intake hose and youll see a plug the size of quarter(ok bigger)
the hose from the bov exit (ie the "horn") needs to go there.

 

[eric91gst]

so i dont need to get rid of any of my piping or move it around, i just have to run a hose form the bov to the intake. when u speak of intake does that mean the hose the air filter hooks onto. also what kind of hose should i get to do that. doesnt the horn unecrew and then u can get hose to thread into it so u can recircualte?
-thanks, sorry if i had some dumb questions that needed to be clarified

Usually you can find some radiator hose that will be properly contoured (with some nudging) to fit between the BOV and the intake pipe. The intake is the pipe/hose between the air filter and the turbo.

 

[eric91gst]

ok, but doesnt the radiator hose have to be threaded on one end to go into the bov since i think the horn unscrews and then i can thread something into that instead of the horn to reculate it. also there is a k and n littel filter that sticks up from the intake. is that the hole
i want to put the hose from the bov to the intake into. all i do is take that off and put the hose there in its place. right?

 

[nightspeed87]

What??? Yo learn about what each part in your engine does and what its called maybe well make more sense. Basically what theyve been trying to say is connect the hole that shoots the air out on the bov with any kind of tubeing that works, ( flexible rubber kind in your case since youll need something that bends ) to the intake arm. ( the piece of rubber tubeing that goes from the intake filter ( knN) to the turbo itself).. If its the stock intake arm then there will already be a hole that connects this. Doesnt matter how you do it as long as they connect and theres no leaks it should work.

You'll need to do one of two things:

1. Buy a stock 1g BOV and recirculation hose. You can do this at either a Mitsubishi or Chrysler dealership. (Talon/Eclipse are the same car, so just say whichever is appropriate for whichever one you're at.)

2. Buy a recirculation kit for the BOV you have. This will usually come with a fitting that will replace the horn; it'll screw in where the horn goes. From that fitting you'll have to use some sort of hose or tubing to connect to the snorkel tube on the air intake pipe.

For your car to run correctly, you must recirculate your BOV unless you decide to go all out and go with a MAFt setup, which you aren't ready for. Do NOT put a filter on any open ports on the intake. This will bring unmetered air into the intake tract and cause your car to run lean, which could damage your engine. If there is already a filter on the intake, take it off and cap the hole until you can recirculate your BOV.

I notice in your picture that there is an open nipple on the valve cover. There should be a vacuum line from that nipple to a nipple on your intake pipe. Make sure that is reconnected, otherwise that nipple is going to leak oil gunk all over your engine bay.

in all practicality, yes you do.

There is no recirculation fitting availible for the TurboXS RFL blow off valve.

But, the horn is threaded, which means you can unscrew it. With the horn unscrewed, you now just have a threaded shaft in which you can push your radiator tubing over, and it should hold pretty well even without clamps (considering the BOV is threaded). You then take this tube and connect it back to your intake.

Now you have a recirculating TurboXS RFL blow off valve. Be happy that your car now runs normal.
