I put in the new Opti...

[tred95]

Now I need a little help. I'm replacing the vacuum vent lines and when I separated the parts, I'm not sure I remember where each one went.
Does the one with the 5/16 to 3/16 adapter go to the blue restrictor, check valve, and intake? That's the way I have it now.

Thanks, its probably the only thing that I didn't mark with tape.

:duh

Looked thru the manual which is no help, at least I coudn't find anything.

I'd give Jeff Koop a call at Superior Chevrolet. 800 728-8267

He shud be able to help.

Rabbit,

Thanks for the look-up. One of the first things I did after buying the 'vette was to get the manuals...pretty salty, but well worth it.

Unfortunately there are some things they do not show and some things are very hard to find unless you know their terminology.

I will give Jeff a call...

Thanks again!

Here is the assembly order. The plastic male vent on top of the Opti runs to the driver's side top of the black neoprene intake runner. Make sure that has vacuum when you get her fired up. The steel male vent on the bottom of the Opti runs up to the white side of the large 2-way restrictor/filter (this one is NOT a check valve; it can flow 2 ways). The blue side of that travels up and over to the white bottom of the small 1-way check-valve. The blue side of that little guy runs straight to the front of the intake manifold, just under the throttle body assy.

I hope that's what you needed. When reassembling the neoprene intake runner, make real sure that the Opti vent hose running to the front of the manifold does not kink. Otherwise your vent sysem will be inoperative. That happened to mine.

Ted,

Wow! Thanks a lot. I had it bassackwards. Did you read the tech article on Corvetteforum about instead of going to the neoprene intake runner, running the hose to the interior of the car.

Supposedly it is to suck less humidity out of the incoming air.

Don't know yet if I'll try that.

The air passing through the Opti and into the intake manifold is measured by the MAF sensor. Pulling in air from a non-MAF metered location is not a good idea.

CYa!

Unless you run the a/c (which wrings moisture out of the air), you're not really lowering the amount of moisture that will get into the Opti.

On cold days the air in the cabin may feel dryer because it has lower relative humidity after it's heated up, but it's holding the same quantity of moisture as it did ouside the car. In the summer, with the a/c on, you will be drying the air before it gets to the Opti, so that will help.

I do see one big advantage to having accesss to the end of the vent tube - If your Opti ever gets so much moisture in it that it won't start, you can dry it out much faster by blowing dry air through it.

My sentiments exactly SR94.
