bluedotsnow Posted May 10, 2014 Share Posted May 10, 2014 EPIC expencive OOPS! hopefully I can get this welded back together.... Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 10, 2014 Share Posted May 10, 2014 (edited) ha ha, the entire bung sheared off!? exhaust shops routinely weld in new bungs, they've got them by the boxes and do it all the time. clean it it up well, get all that rust off there and you can easily weld in a new one or the old one. i'd use a new O2 sensor bung so it's fresh, clean metal. you can weld so you won't need this but if anyone else ever finds this thread, a non-welding repair might be to get a tap and thread the hole for a spark-plug non-fouler (O2 extender) and just thread it in.

Fairtax4me Posted May 10, 2014 Share Posted May 10, 2014 That's an easy weld for an exhaust shop. Especially with the cat already off the car. Just drag it up there and have them weld a new one on. Quote Link to comment Share on other sites More sharing options...
bluedotsnow Posted May 10, 2014 Author Share Posted May 10, 2014 that was my first thought fairtax but its saterday so they are all closed.... the one I spoke with said they could do it but not untill monday and for $85... my thought a new harbor freight arc welder is $100 I'm going to spend the extra $15 and go all Jeremy Clarkson! but first to parts n wrecks in sacramento for a new to me ypipe. I just hope I don't need 02 sensors on top of this but C'est la vie btw take a look at this after market crimp and twist courtesy of a rock I hit at 50mph... honeycomb looks shiny clean and intact! way better than I was expecting!

Fairtax4me Posted May 10, 2014 Share Posted May 10, 2014 Yeah that's a nice custom bend for sure. Just tap the cat with a mallet a few times and see if it rattles. If it sounds solid then its good. $85!?! That's three minutes with a wire brush and less than a minute of weld! Is there a welding shop in your area? I had a filler neck TIG welded back onto an aluminum radiator for a 4 wheeler for $50, and he had to straighten part of the end tank before he could weld it back together. And the guy did it while I waited. Quote Link to comment Share on other sites More sharing options...
Junkie Posted May 11, 2014 Share Posted May 11, 2014 Seriously, $85 sounds like way too much. If I had my welding gear up here I'd offer to do it for you. If you do pick up a welder be aware that the HF ones are pretty shitty. Practice on other stuff first, too. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted May 11, 2014 Share Posted May 11, 2014 yah, cheap welders aren't well known for laying a clean, nice bead. though i don't have any experience with the arc welders from HF, the wire feed migs are hard to dial in just right.

Junkie Posted May 11, 2014 Share Posted May 11, 2014 On top of that, it's likely very thin material that you're welding something thick to. Not the easiest thing to weld up if you're new to welding. Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted May 14, 2014 Share Posted May 14, 2014 I would say braze it! Quote Link to comment Share on other sites More sharing options...
bluedotsnow Posted May 14, 2014 Author Share Posted May 14, 2014 cat seems to be leak free I'm going to put the car on ramps and have another look at the exhaust system. among other things I need to straighten the hanger bracket from the last smashed pipe...
