Cracked Catalytic Converter
Guess it's that time, when problems start showing up! 147000km.
At $2000.00cdn to replace the left side, I'm trying to take the cheaper way out and get it repaired (welded). From what I've read, seems to be a lot involved in getting it out of there.
Here's a thought.......and looking for feedback!
Unbolt the Exhaust from the manifold.
Cut the pipe on the straight section just before the bracket at the Transmission crossbar.
Disconnect the sensors and wiggle the CAT out of there.
Get the CAT welded at the crack. Wiggle back into place and bolt to manifold.
Weld the Cut in the Pipe.
Would this not work? Avoids dismantling the Torsion Bar, etc. Saves time and money?
Any comments? Thanks for all input!

It's cracked on one side, so I wasn't going to completely break it apart! The truck runs great, so I'm guessing it's ok.
I don't know of what to look for when checking the catalyst!
Thanks Again!

I have never seen anybody get a left side cat out without taking the torsion bar out. The right CAN be done, but not worth the hassle IMHO.
Seriously with the reputation of cats lately rattling and clogging I would replace it.

Just an Update!
Temporary Fix.
Bought me a Muffler Patch from Crappy Tire and wrapped it good. Noise gone and not leaking! Till I can afford to make a decision!
I also inspected the other side.......what looks like a hairline crack developing.

Review the threads in the links below. I fixed my driver's side cat in May of this year, and so far no more problems. I've put 10K miles on since repair.
