Y pipe Leak

[john_eckels]

I think I know the answer here but I will give it a shot. I have an annoying exhaust leak around the front oxygen sensor. It had no gasket, so I got a new gasket today and put it on and no improvement. I noticed that the inside of the oxygen sensor mount had some chunks rusted out of it and that is where it is leaking. For a quick fix, I doubled up some fiberglass cloth, shoved it in the crack between the pipe and gasket and tightened the bolts. It seems to be holding.

I think I need a new Y pipe, and I think it is expensive. My friend offered to try to fill the void with his Tig welder. I think the spot is too had to get to and I am not sure if the weld will hold on the rusted pipe. I also thought about trying to fill it with JB Weld, but I am not sure if it will withstand the heat. Any suggestions here? Thanks in advance for any input.

Forget the jb weld

That stuff won't really hold up over any period of time, but a tig weld certainly should, if properly done. If this were my rig, I would do a temp repair till I can replace the whole section (at least).

There are a lot of great threads here on exhaust mods. Choose a favorite and put it in your plans.

Hope this is helpful.
