96 dohc vacuum diagram

[dohcfiend]

i don't know about the newer bodies but the older ones it was right beside the hood latch.

Can some1 snap me a pic of that diagram?

Which ones are you having trouble with? I can possibly help you out.

Here's a picture of a 97 motor... the only lines that aren't hooked up are: brake booster, and the vacuum ball line which is right next to the brake booster. Not pictured is the PCV which uses the nipple on the side of the plenum below the intake arm mounting.

i need all of them. i am putting a 96 motor into my 94 lumi and i don't have a 96 diagram. i really don't think it matters a vacuum port is a vacuum port? but i will make an effort to get everything to the appropiate ports within reason.

judging from the pic it appears the only ones left is a connection to the vacuum modulator on the tranny, and the connection for the purge/accessory connection.

Here you go homeslice:

appreciate it. got it saved too. 2 connections left. the vacuum modulator and the accessory connection. u have any idea what that port next to the brake booster goes to?

[dykz34]

The smaller nipple next to the brake booster line is for the vacuum ball in the fender that is used for HVAC, cruise, etc.

[dohcfiend]

sweet that is the accessory connection i was referring to. so where does the vacuum modulator on the tranny connect?

[dykz34]

I dunno... 96's didn't use that.

[dohcfiend]

didn't know that. perhaps i will set it up like the my setup then. on my motor there was a t in the vac line for the charcoal cannister purge valve and that was for the accessory connection.

perhaps i will do that again and use the connection next to the brake booster to go to the vacuum modulator.

Do u think that will work ok?

The CCP on the 97 motor is the two black boxes that are bolted above the fuel rail. They draw vacuum from the TB. For the modulator on the tranny, I would just use a T-fitting on the accessory line to split it.
