A new elbow is $250.
I’m sure I need all new piping.
I can’t afford it now.
Any ideas are helpful!
Thank you

No used ones on EBay but there was slightly less expensive ones.
I’ve had a welder help me before.
I haven’t examined the muffler system yet, but If I find rusty holes, could i use some of the JB Weld High heat products for a temporary fix.
I don’t have the money to do her right yet. _________________ 1976

I'd use JBWeld high heat putty. And simply delete your EGR. _________________ -Ian

That EGR doesn't look like it's worked in years.
My farmer fix for that would be to ball up some wood stove gasket cord and clamp it over the end of the hole with a big long worm hose clamp. Of course that would be *temporary* until I could repair it with a welder. _________________ Rust NEVER sleeps and stock never goes out of style.

once those elbow clamshells start to fail it is simpler to just replace them. Jan Blair of Blair and Son's wrecking, (the third link) has a good used one for $70. I'll bet one could get him down enough to pay shipping. The bus is in California so it has to have a working EGR to pass smog unless BAR waives the EGR, which they do sometimes on Catalytic equipped buses, but not always. There are two gaskets plus the EGR gasket, and new bolts, washers and nuts needed. Whole repair including a temporary EGR block off would be under an hour and $100. Someone please explain to me why we need to do it any other way. If someone is welding and they pooch the crossover or heat exchanger, or dingleberries get into the catalytic it will only get more expensive. I get that people want to be frugal, but damn near everyone here had their bank accounts loaded with lots of cash this year, and some of our neighbors got as much as $25,000 USD tax free depending on what their financial status, and children count were. $70 is too much? |

I agree on doing it right. But that is not a one-hour job, even on a dry bus. The system looks original, so count on some rusty hardware needing special attention. Plus, the flanges are likely bent and need to be straightened to get a good seal. Then they should be finish filed flat… Maybe painted?
Your biggest, baddest vise grips can pinch the tube shut for now. Remove the EGR rod until you can spend a day fixing it properly before your next smog check.

My understanding is that the elbow is cracked, and not a warped flange. If the flange is warped and that is the leak you would be correct.
they are just replacing a cracked elbow. The bolts will be seized and can be twisted off with a couple closed end box wrenches. That is why new ones will be needed. Don't even mess with trying to save them. Someone young and flexible like you should be able to do that in 30 minutes Robbie if an old fart like me who is old and worn out can do it in 20 minutes. I swapped that whole area many times when working on fitting the Magnaflow cat project. The only "if" is if the pieces are too tight together, loosen the left driver side U pipe to heat exchanger a little to get more wiggle room. Those bolts may need to be replaced also which would add 20 minutes, three bolts, and a gasket. Use the older gaskets that compress better rather than the newer thin ones that don't take up any deformation. Some week when she has time she can redo the whole exhaust but for now just get that elbow.

The elbow isn’t cracked. There is a shadow in the pic that makes it look like that.
I looked for more damage, didn’t see any.
I’m lucky enough to live in a handful of counties that don’t require a smog beyond the first time registering.
There is legislation in Sacramento the would change smog requirements to 1984.
I’m going to try to press the EGR hose shut and the JB weld on the elbow for now.
It’s illegal to sell block off plates in California.
I just won’t be able to sell her unless the law changes.
Oh well. Lol

And yes, the bolts are tragically rusted. _________________ 1976

Elbow, silence the putt putt putttt...., pull the electrical plug off the EGR (flying saucer) to disable the valve, the pipe can dangle open after that. _________________ Rust NEVER sleeps and stock never goes out of style.

I only see one UFO Thing and it only has a hose on it.
On the distributor?
Remove the UFO? _________________ 1976

Nope, not on the distributor, it's bigger and up front:

the early 1976 electrical EGR is a disk. The 1976 1/2 manual EGR is a square block. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

Mine was manufactured 3/76.
Found the other disc, near the charcoal filter.
Maybe the link is under it? _________________ 1976
