Use great care disassembling an EGR valve. They can easily be destroyed. Many solvents will ruin the diaphragm too. A working EGR is a terrible thing to lose.

Well, I don’t know what all that was about.
I was looking around at the EGR to remove it.
I noticed the carbon air hose was disconnected, I put it back.
Thought I would try starting it with the rod disconnected.
It worked!!’
All I did was put new wires on, new cap & rotor.
And condenser.
I haven’t done the plugs yet.
What do you all think? |

there is a spring inside the valve. Make a blocking plate and put that under the valve for now.

Yes, the spring is loose now.
I don’t know how to stabilize it.
What can I use. |

so the valve has two sides to it. One side is closed at idle and the other at wide open throttle. There is a small spring in the valve that closes the one side at idle. The diaphragm prevents air from seeping into the valve and getting in as a vacuum leak. If the bus will start with the valve hooked up, then most likely the mixture is whacked from the prior owner trying to compensate for leakage at the EGR. I'd block it off with a plate, and try to start the bus after that. Who knows what the PO did to accommodate mixture problems.

| If just hooking up the rod causes your engine to die, I suspect that something is bent or not positioned correctly. |

used valves if you can find a good one. Interstate in SoCal sells "rebuilt" ones, whatever that means. They want about $300 for them. The rods come up for sale too sometimes. Have to watch for the parts. It has been NLA since about 1990. I have never seen a new one, come close to low mile ones a couple times.

Interstate VW parts in Lake Elsinore sells rebuilt valves. They do not disclose what goes into the valves, rightfully so as they are devilishly hard to replicate and rebuild. Try at your own risk, or make your own out of sheet silicone, and replace it every thousand miles.

what is "it?" If it is the diaphragm, no.

The EGR valve has a rubber diaphragm inside it. If it’s ripped, it leaks air (vacuum) and can stall the engine. With the rod connected/disconnected, the internal rubber diaphragm moves slightly and the air leak changes size. Remove the valve, make a block off plate for the plenum, and run it. If it runs well, welcome to the crew of folks waiting for solutions on EGR valves.

No wonder I couldn’t find them, I was looking in the fish section. I did find a zhalibut though. Where to leave it?

Well I finally got around to working on my tune-up.
I found a wire broken.
I think it goes to the temp regulator/fuel thingy.
Charging now.
Fingers crossed! |

Lake county.
I don't understand your problem. If the rod is disconnected then the EGR doesn't affect your engine unless it is leaking gasses or has a bad diaphragm. If your bus suddenly started dying it is unlikely to be the EGR. You have some troubleshooting ahead.
