What hose should I attach the smoker to test for a vacuum leak?

Mark,

First, your WUR-072 is not vacuum assisted. Vacuum is never applied and used for this particular type of WUR. Some of the advises offered to you makes sense others are just garbage. So be careful whose direction to follow.

I have a strange feeling that you don’t know or understand how to use the Smoke tester tool you have. You need to isolate the CIS unit (airbox, throttle body, and intake runners) to perform a pressure test using a smoke generator or machine.

You need about 5 mins. to do your fuel pressure test and 30 sec. for your vacuum or air leak test. Do these two (2) tests first to understand what is going on with your engine. I am betting my money on unmetered air.

So what happened to the missing rubber hose connected to the top of your WUR? You might have also a nipple at the throttle body left unplugged. Could you post a picture of the throttle body and air filter housing? Thanks.

What do I need to remove to get a picture of the throttle body? Just to reiterate. I know nothing about these cars.

Mark,

For this investigation, just remove the air filter cover (snorkel) like shown in the above picture. I like to see the area between the throttle body and air box from the driver side viewpoint. There are two (2) small nipples above the butterfly valve on the throttle body. Thanks.

Mark,

In the second picture where the black/blue hose is connected, there should be another smaller nipple. Now, to get to the bottom of your problem let’s identify your throttle body.

Look closely in the last picture you posted. To the lower left of the spring is an aluminum strip I refer as label. Please post the last 3 digits stamped on the label and post the number. While you are there, take also a look at your fuel distributor number. Post the last 3 digits. Thanks.

Tony, I don’t see another nipple or a tag or number. Maybe the tag was removed.

Thanks for your help but I’m going to take it in to a shop. I’ve driven the car a total of 140 miles since I bought it last year. Going back to my 1965 Mustang.

Closed thread. I’m out of here.

Encircled is the aluminum tag or label for the throttle body. I think you are making a good decision to take it to a shop.

Let me reinforce the sincere welcome. The stuff you
are learning today, you will pass on to the next new
911 owner with a fresh perspective. We are all here
to help each other.

One of the things you will find unique to this Forum
is the ability and willingness for everyone to state
things correctly. I post something in error at least
once per month. There is this wonderful feature
called an “Edit” button that allows me to post the
error acknowledgement and the correction.

Most of my posts try and answer the question at
hand but also provide the detail for the wider
issues that someone might search on. When you
see someone posting far more detail than necessary,
they aren’t being condescending to the questioner,
just providing archival information.

Additionally our host has a “Search” function.
Understanding how that works and the “key
words” is critical for the efficient use of the Forum’s
extensive archives.

BTW, Please post some images of your “new” 911.

Best,
Grady
