Catalitic converter woes

Mickb

hi all

I have a 1998 Volvo V70 T5 and live on Central coast NSW, has got a rather annoying rattle from what I believe to be coming from the cat converter, would anybody have a good used one up for grabs atm, or know of the best place to get one to suit 2.3 turbo ?

Any responses would be greatly appreciated.

The easiest less hassle way is to call the local exhaust shop

Have seen success with screwing appropriate length tek screw into the body to secure the matrix.

Thanks,

Snoopy, sound like a good emergency fix, any idea on length and location for the screw ?

The noise is driving me nuts, not to mention embarrassing ?

I would jack it up and run the vehicle double checking its not a heat shield or exhaust rubbing some where before I drilled tech screws in my cat. It a catalyst so it will break up and go further down your exhaust.

If your sure its your cat for a home free fix remove it and punch the inside of the cat out with a long extension and a hammer.

3 bolts on the turbo and 1 clamp. Remove the front section of the exhaust and bash out the cat.

No fault codes no issues unless you need a emissions test

This is front exhaust with the cat section looks like this

My mate used a 30mm odd one and tried his luck. The matrix will take a screw no problem. You can't tell where the break is so tap and see if it rattles , go in there.

If you want to be anal you could put muffler putty around the head when screwing in.

It fixed mates car. It will still do its intended job which is clean the evil gases from exhaust as unleaded without catalyst is actually worse than leaded fuel.

Thanks heaps for the advice guys, looks like it's under the car for me, hopefully for me it's the heat shield that's noisy after travelling on our wornderfully smooth roads ?
