Small exhaust hole at the weld V70-XC70 2009

Klaus,

you know I am a glutton for punishment. I just had an oil change and tires rotated on the 09 XC70 at 85K. We call her the Immaculata because she mostly lives in the garage and goes out when we truly need AWD. Anyways the Immaculata is our best horse and we hardly drive her 5,000 miles a year.

And so the latest is that despite over care and sensitive operation, there is a small exhaust weep at the weld on the pipe which crosses to the second pipe. I would have been in the mood to ask the independent if there was a life hack for that, but the independent is focusing on more expensive automobiles and as I get older I am becoming more invisible.

So is there a life hack for a small hole in the exhaust weld?

I am expecting it to be bubble gum tied down with nude panty hose. Again, please excuse my sarcasm but I thought it was common knowledge that the Volvo exhaust is stainless so there shouldn't be an issue with it.

THE thing a welder wants to avoid is burning a hole through work upon strike-up.
This goes double for thin metal.

I'd go for a welded repair as the "weep hole" will only enlarge.
Seek out a good muffler shop where they MIG weld routinely and tell them your tale.

If confidence doesn't result I suggest cleaning the hole of soot with whatever gauge wire works and try J-B Weld. Use some kind of strap or hose clamp to support it.

You knew all this.....

I wish I knew all that. So a welder is the guy who can fix it. I will go to a muffler garage and see what story they can tell me.

Thanks for the heads up.

How about drilling a nice hole to plug with a screw. Include flat and lock washers.

Sometimes simpler is better. I will need to take a closer look. I was just so exasperated to be looking at a part of the car that thought was bulletproof.

Thanks for the heads up.

I wouldn't use bubble gum, it will expand with heat and the drag of the bubble on the ground will probably stop the car.

Yes, the exhaust is stainless, but the welds are not. My guess is that you got an exhaust that was welded just about quitting time on Friday.

Isn't there a welder around you that could re-weld it? The pipe itself isn't compromised, just the weld.

On my 1967 122, I used a soup can and a couple of clamps. But that exhaust pipe was just about gone and not a weld.

I will take a better look at it. And have a welder look at it as well. I need to get more eyes on the vehicle.

Thanks for the insight.

Try furnace cement. Worked well on a couple of small holes in the exhaust header pipe on my 240 years ago...

I am going to try furnace cement. And I am going to enjoy telling the story about the furnace cement rated for 50,000 miles.

Thanks for the heads up.
