Bright red cat

[Zuicider]

turned the car on today and the cat was glowing red. does that mean its rooted? it even melted the high temp paint on my exhaust rated to 1300 degrees

This either means you have unburnt fuel getting into the exhaust and the heat of the cat is igniting it. Or the front of the cat is blocking up creating a bucket load of backpressure. Get it fixed as you will melt the cat and stuff the O2 sensor. Undo the front of the cat and shine a torch in there, you should see a beige looking honeycomb ceramic brick. If it looks all melted or hollowed out it is rooted.

Dont bother getting a new one, just bash the innards out with a bar...

Hi-Flow cat, but FREE!

just dont get caught by EPA or that "free" will suddenly be $10,000, not to mention the cost to the environment, but lets face it... big industry does a much better job of ruining the environment than a V6 commie with no cat could ever do.

But you get every dikhead with VN bashing cats out and it will make an impact. Oh and while you at it take out the mesh in your microwave door so you can see the food better.

the thing with cat's is, they probably all lose thier effect after 10,000-20,000km.

Yeah they say cats dont last any longer than about 5 years anyway.

Thats what i heard aswell.

[Not_An_Abba_Fan]

Legally a genuine cat has to last at least 40 000kms when the engine is properly maintained. Aftermarket cats last longer. If you look after your car then there is no reason a cat won't last 80 000kms. The key is regular maintenance and the correct fuel. Checking error codes at every service will give you an indication of what the car is running like and if anything needs attention, do it.

nope, not true, i may not know as much about cats as alot of people on here, but go and hollow out the cat and you will straight away notice a dirty smell that wasn't there before

You are smelling the all the crap that the cats are designed to convert. Really healthy too.....

Yeh it smells a fair bit but i found that it gave the car a much better note after bashing the guts out.
Rougher, i suppose you could call it, havent heard another commodore sound like it yet.
Sounds very good in the 5 speed.

[Not_An_Abba_Fan]

Tracks Soybeans IP address and rings the EPA......

[pow3rslave]

is this it?

[VHSLX3300]

lol.....i replaced mine with a second hand cat a few weeks back. dont bash the innards like every other commodore owner does for some reason. theres no real gain anyway. but yeh by the sounds of it its screwed if its glowing red

err its a brand new high flo cat. sumthing smashed into it when i took it off the car trailer. looked alright when i took it off before i got the motor starting. i was doing work on the car and forgot to put the 6th ignition lead on. *smascks head*

its because of screw driver specials we have water restrictions!, hippies... ATTACK!

[Zuicider]

i ran up the motor just then, and its sounding ****, like making ugly popping noises, not the normal popping noises, so i guess ive melted the inside. will check tomorro

[greenfoam]

yeah if you run extra fuel into them like leaving one cylinder not firing they will get realllllllllll hot. My boss had a pushrod not sitting in the rocker properly and one rocker wasn't closing and that cylinder wasn't firing which on a ford EFI windsor means that so much extra fuel was getting into the front 4 cylinders back up through the manifold that none of those 4 were firing at low revs and the cats go so hot so fast that it melted the paint off the floor of the car and almost caught a rag on fire that was under the drivers seat (made it burnt brown in colour !! )

[Zuicider]

:P, could still see through the cat, but it was distorted. put on a normal one from the vr wreak i had and she sounds mint and runs smooth as. 2 more weeks and i will be carving up perth once again
