ID these HEs

Edit: Nevermind - I think they are B&B.

They are B&B, but not all B&B are the same and there are cutom versions out there as well.

Those are B&B, Carrera, either 1.5" or 1.625" I.D., well used I might add

[bbh03]

They should be usable though right? I thought these things were pretty much indestructable. Maybe bead the outside and ? the inside???

[Bill Verburg]

Yes, that's all just surface tarnish, those things are well built, the stainless will last forever.

I would just use them as is, except any oil that got into the exhanger part should be cleaned out.

[bbh03]

There is oil in the header portion of one of them. Should I just flush it with solvent and dry it?

[Bill Verburg]

If there is oil inside the exhanger(not the exhaust pipe) you can try to clean it out, but it's usually baked on pretty well. Try solvent but be very carefull when it's time to put back into service, you will want to be sure all of the fumes are vented overboard before you need heat in the cabin.

[bbh03]

Nothing in the exchanger portion, and I can;t think of a reason for oil to ever get in there. Oil did come out of the exhaust portion on one side though.

They will clean up like new. The headers are built like battleships (and hence a good value on the used market.

If you look closely where the stubs come up from the exchanger there is not a solid seal.

Oil can drip down the stub and into the exchanger chamber.
