vacuum line identification

Featured Replies

Still working on this project someone else took apart.

 

I need help identifying a vacuum line/tap.

 

On the back side of the #3 cylinder intake spider there is a very small ( maybe 5mm) intake tap. I cannot figure out what line goes there and to what.

 

It is the 97 2.2 Lego Anyone know? Can't find a picture and the diagram on the hood and in the manual is not much help.

 

This project is getting me down. Just found tonight all the AC compressor mount bolts are missing too.

If it's anything like my '92 2.2 then it leads into the aft end of the fuel rail by way of a metal tube. It starts off rubber hose, then about 5 inch's of the metal tube, then ends in rubber hose terminating at what looks like a pressure regulator.

Thanks, I have a feeling my son left that metal tube off when he installed the intake.

What exactly is this "project" and why would the metal hard lines have been removed from the intake?!? I've never taken those off. Is the engine original to the car? There were about three or four different vacuum routings over the years on the 2nd gen EJ's..... if the engine came from a different car it might not match up to anything. The trick is to follow the lines and find out what they go to and make sure everything has the vacuum signal that it needs....

To make a long story short. Someone pulled the engine to swap it, since this one had bent valves.

 

The engine he brought was no good, so removed the heads to have them repaired.

 

He quit, and left - everything laying around the shop.

 

My son ( it's his car) decided to remove the intake and paint it red. That is when the tube was removed.

Will do that tomorrow, after I fix the rabbit hutch.

Just run a rubber hose straight down there to the fuel pressure regulator. That's how it was done on the older cars.

Okay, found the place to connect to hose to the manifold and the regulator,

 

However , I found this metal pipe on the cart, that I have no idea where it goes. It still has some rubber vacuum line on it from when it was removed,.

That first pic I posted is of my '92, 2.2 in my wagon. All the others are of this EGR, 2.2 manifold I picked up somewhere. Pretty dirty, but mostly complete. Maybe some of these pic's will help.

Thanks,

I'll check, but I don't think this is one of those lines on your manifold.

 

My EGr is hooked up, the fuel press regulator is hooked up and the engine runs (not well without the airbox on it.)

 

Since this line is painted black, I think it has something to do with the air box, filter system.

Probably one of the evap system lines. I've never seen the hard line with the T in it like that though, so I can only guess where it goes. I'm pretty sure it has nothing to do with the airbox though.

 

Is this engine original to the car? You can look on the bottom of the hood there is a sticker/label with the routing diagram for all of the vacuum hoses.

Original engine.

I may get a better idea when the air box is on. Hoping someone would recognize it.

Looking inside the tube, it has a white powdery build up in it. Smells a bit like solvent.

 

Looked at a friends RHD 97 and cannot find it on theirs.
