I am Gussing you mean that retarded 3 bolt flag before the cats…try to get the other 2 bolts out then drill out all 3(will probably break the other 2 trying to get them out) and replace them with nut/bolt and don’t forget to change the gasket
I second this^
No not after cats before cats the 2 bolts that hold cats to headers
Ok (older ones has that 3 bolt flanges before the cat) same advise get the other bolts out then drill out and replace with nut/bolts and don’t forget the gasket
Pic would help alot also
Cut it off, weld a new one on. Or just cut it out and weld in a piece of pipe.
Where the cat meets the header What the c clamp is holding up lol
Cant get a welder around it if i cut and cant fit a drill in there or the other side even it i could drill it probably couldnt even fit a wrench in. took about a foot and ahalf of extensions to even snap that
Well you want the bad news you have to take the exhaust system basically off the truck…what motor is it
Basically what i thought and its the 4.0 but it these bolts are this bad the header ones are probably the same
No don’t take the header off just the y pipe take the other 2 off the other side in the same spot and then you will have room to work on it you don’t want to risk breaking the bolts off in the head then you have to take the heads off the motor to drill them out
The one on the other side is turned right up against the engine so one bolt will be a bitch if i can even get to it gunna have to do a lot of test fitting
This is the other side
It has to come off…swivel and extensions are your friend..alomg with heat lol
Thats what snapped the first bolt
That’s the thing one bolt can fuck up your whole weekend
Drill hole in it and use an easy out.. You can get the easy out at Home Depot
Its so rusted in there they wont even turn even with the manifold flange cherry red they just snap
Don’t get the manifold cherry red you can snap that ear right off then you will have to temp to take it off the head
So best bet just try and grind off the bolts that snap flush to manifold and drill them out and just nut and bolt them up
That’s what I would do
…the ones that snap off I would, the others I try to get them out first
Okay thank you should be a super fun weekend
Start soaking them now with pb blaster every day as much as you can and when you go to take then off if you can get mostly straight on it smack the extension with a hammer a few good times befor you trying to loosen it
Beat it out then use a nut and bolt with anti-seize
It will never happen again
