Default Intake removal

Hi guys, I know this is my first post (ROOKIE) but I have been an avid reader for a long time. Anyway, I used the intake removal advise that is on this forum and it worked beautifully. One thing that was cautioned was the small vacuum hose on the back of the manifold so I was very careful when sliding the manifold forward. The issue I'm having is that the hose was connected to the intake but not connected at the other end. I have no idea where it is supposed to hook up and would appreciate any help. Thanks in advance.

Look behind the intake area. As I recall, it comes off of a T fitting that sits behind the intake slightly to the passenger side of the center of the car. The lines are part of the A/C system.

I do not understand what you saying! The hose connects to the MAP sensor and the other end goes all the way to the botton of the passeners fender (INSIDE THE main wire harness) and connects to the bottom of the resiviour tank.

Something that you can do to make life easier is lengthen the hose.

It has probably broke off inside the main wiring harness. I would replace the whole line from intake to vacuum cannister.

I believe that you are both correct. Bill thanks for the pics. BigGun, it must be somewhere inside the harness. I'll run a new line outside the harness to the vacuum tank. As soon as I locate it. Many thanks to both of you.

Out of curiosity, what problems were you originally having that led to removing the intake manifold?

Oil leaking out of the pressure sender. As a side note, doesn't look like that vacuum line has been connected for a long time (someone else has changed the pressure sensor before. I've probably had a vacuum leak for a long time. The a/c seemed to function ok though??

Another good case for replacing the oil pressure sensor the correct way, by removing the intake!

You probably never would have found that broken vacuum line if you tried to replace the sensor using one of those short cut methods, and not taken the time to remove the intake. Good job Mike.

Without that vacuum line you will not be able to switch vent levels and you will most likely have a check engine light (unless the AIR System has been tuned out by a tuner.

You can find the line inside the harness and splice in a new line section easily. NAPA and AutoZone both sell a nylon line repair kit.

Well Bill, I put a six foot line on the intake and reinstalled the manifold thinking I would run the line directly to the canister. This was done prior to reading your last post about going into the harness. Can I access the vacuum canister by taking out the battery? I'm not being lazy, just thinking that the next intake removal would be much easier with the vacuum line not being in the harness. When the intake comes off again, I'll put the line back in the harness.

If you ever have the manifold off again, consider adding a length of vacuum hose from the the rubber elbow to the vacuum connection behind the manifold. The rubber elbow is clearly visible in Bill's photo on post #4 of this thread.

I used a straight 1/4 in. vacuum splice, inserted into the vacuum elbow, and about 4 inches of 1/4 in. of rubber vacuum line to connect the other end of the splice to the vacuum source.

This will take the strain off that plastic line, and make if a hell of a lot easier to reconnect.

Great idea! I will do exactly that next time I take the intake off. Thank you.

Well, all back together except for the vacuum line. Car runs great. Really appreciate all the help from this forum. Bill you were right, the blend door will not change position without a vacuum source. No CEL though. Again, thanks for all your help.
