Title: bypass valve
Post by: annie151 on May 06, 2009, 02:53:00 AM

I am working on my own car and I am sort of mechanically inclined.  I have an aftermarket issue though...  Does any have a picture of a bypass valve?   I had been told to order bov valve in place of one but I am having a difficult time on how to install it?  Is there an aftermarket kit I need to order?

Hey Annie!  If you ordered the one Rocketman featured then it's an easy adaption, if not then you've got hell to pay. To answer any further would require a picture of your unit.  Gus

Hey Annie! This in suppliment to the existing unit. I thought there was a photo showing it installed in one of the posts. I don't know how to post photos so hopefully someone can butt in with a photo.  Gus

Guss, this is to replace the old unit - you do not keep it.

Annie,

Find the crossover pipe on top of the valvecover - its the silver metal pipe running over the top of the engine. On the right side of it near the throttlebody - there is a small piece of rubber hose that connects the crossover pipe to a metal hardline. The hardline will run off the side of the engine past the distributor and make its way down under the turbo intake pipe. The stock bypass valve is down there, you'll find it by tracing the line. Its round and it'll have two 3/4" hoses and a vacuum line on it.

You may be able to directly replace the stock valve, or you might need to get some flexible hose of the proper diameter and get creative. As long as you have the in/out properly connected everything should be fine. At one point I replaced that metal hardline with a length of rubber hose, you might need to do that.

Maybe Grant can post up some pictures of his install?

-Matt

I might be incorrect but... I think it is in backwards????

Title: bypass valve
Post by: annie151 on June 15, 2009, 10:31:00 AM

really?

I don't think it will hurt it if I turn it around...I can try it.

It does look like it is installed backwards - can you get a picture or describe the ports on it? Try running the recirc as open (plug off the return to the pipe first) you should hear a pssshhht or woosh as a blowoff. If not then it is in backwards.  Did you happen to get a diagram with it?

No, I did not get instructions...this is the one I have ordered on ebay...per your instructions.  I have contacted the person selling it and she said just remove the old one and install the new one...I gave up.

Okay, I do think its in backwards. The center port should have a piston in it - that piston will move toward the cap with the vacuum line attached, letting bypass boost out the side port. Try switching it around and let us know how it works. It might partially work in the current configuration but they generally rely on the boost to help push the piston open.
