Two part question on an 87 FJ60, exhaust related...

a. There is a tube running from a cast iron box on the lower left side of the engine up to a flange near the carb, held by two bolts. Tube is about 22 inches long, 1 inch in diameter, runs about 15 inches straight back from the cast iron box and then about 12 inches up. The lower side going into the cast part is secured by a slip ring. These parts don't seem to be in the engine, chassis or emission manuals. What are they called or is there a diagram anywhere on planet earth?

b. Problem.... one of the two bolt studs holding the tube upper flange has broken. It will (eventually) get very noisy. What is the part that has the bolt studs and how in the heck to you get in there to replace whatever it is.

I sincerely appreciate any hints, ideas and or ????

Just looks like an ugly job for me but I can't start until I have parts and I can't even identify the parts

Thanks !

 

Sounds like an exhaust gas recirculation. Do you have emissions where you live? If not plug it.
