Hello,
I was doing some cleaning and maintenance on my van and noticed these lines were broken. I was wondering if anyone knew where I could get these. I have looked at junk yards already. Unless someone can explain to me what these do and if I can just eliminate lines. I do not drive in California.



I need the giant metel tube which I assume is for the egr




The grouping of plastic piping is shot they all melted in half



Here is the vacuum diagram. I am slowly cleaning this engine up. The van has 128,000 miles. Sorry for the giant pictures.

 

The metal crossover or supply manifold used to have a check valve mounted at the center where it broke or rotted off. Its not EGR, but is part of the thermactor/air pump system. Part of the smog/emission equipment. If the supply manifold isn't too rotten, you could have a pipe nipple welded to the flange area and replacement check valves are easy to come by. If you have no smog air pump (removed?) then you could weld a patch over the hole, or possibly a cover clamp.

The vacuum lines always get brittle with time/heat and you can replace or patch them. You can use small windshield washer/vacuum line to carefully 'bridge' the broken area's or complete runs if need be.

All dependent on what state emission regs you need to comply with.

 

I do have the check valve connected to the rest of the pipe for the crossover bar, I live in a farming community so emission laws are not a problem.

On the plastic lines They connect to vcv,vacuum control valves. Each one has two hose barbs coming out but three plastic pipes? So one hose barb services two lines. That is where I am running into the biggest issues. finding a fitting two accomplish that. Where would I buy the line to begin with?

 

I guess I could try and find T fittings for the vacuum lines run a small one from the barb to the tee The A/C in the van does not work and I was thinking of removing the smog pump to clean up engine space.

 

Ok,
So all the vacuum lines melted together and I am not sure which ones went where. I have been trying for two days. I even printed out the diagram to blow it up.
The metel cross bar I took a hacksaw to it and cut off the bolted ends turned them around and bolted them back on with red sealant. The problem I am having is the tubing coming out of each VCV. Like what does a TVS look like, or an ACV. I have figured out that if I try hard enough I can get the small tubing out and replace it with windshield wiper tube.

 

I figured out all my problems Thanks

 

Good deal,, lucky you live in an area where it's not a hang'n offense to 'redesign' emission pieces
