CAT problems.

snypereb · 05-01-2006, 06:22 PM

Got news from my mechanic i have had a bloked CAT for the last week turns out i have been blowning pieces of it out the exhaust. What damage can a bloked CAT do to your engine and what kind of prices am i looking at?

Damo · 05-01-2006, 06:26 PM

new cat should be $250 od fitted.

and lol @ me being right. I had the same problem with my EA about a year ago, but the exhaust was blocked, and the car would keep dyeing. I doubt it would have done any damage to your motor.

Not so much damage to the engine, it just creates massive back pressure in the exhaust manifold and makes the car run like crap.

Prices, new you're looking at a few hundred, shouldn't cost more thatn $50 for a second handy.

Most common cause of blocked cats is a stuffed O2 sensor. It makes the car run rich, which kills the cat (Cats and unburnt fuel don't mix).

It was putting stuff all power out because the cat was blocked.

EBFalcs · 05-01-2006, 06:48 PM

get a piece of rod, take the cat off and smash the inside out,

Extra high flow, huge power gain

extra stupid, extra illegal........ did i mention that was stupid and ilegal?

although, if you feel like paying between 10 and 20k fine, go for it!

snypereb · 05-01-2006, 06:51 PM

That would be illegal to hey EBFalcs?

Yeah it was making a rattling noise what does this mean?

gthofan · 05-01-2006, 06:54 PM

what does the cat do, and can they tell if u have no guts inside it???

snypereb · 05-01-2006, 06:56 PM

Isnt it to stop the toxic emitions coming from out your exhaust into the atmosphere?

Oh yeah, the power gains are massive!!! Mate you would be lucky to see an extra 5kW with a hollowed out cat.

And as mentioned before, highly illegal. Not only that, but for a 5kw sacrifice you are actually saving a sh$# load of emmisions from ruining the environment (and us).

Dont to it, its a croc.

snypereb · 05-01-2006, 07:06 PM

Had no intentions of doing it mate!!!!!!

snypereb · 05-01-2006, 07:17 PM

Also says that there is a cylinder miss can this be a result of the cat?

gthofan · 05-01-2006, 07:22 PM

can you also have trouble starting a car that has a partially blocked exhaust??

EDXR6T · 05-01-2006, 07:23 PM

well my cat rattles but i have no running probs just that noise
so im guessing the insides r burnt out

snypereb · 05-01-2006, 07:31 PM

Yeah be carefull my car was supposably blowing out bits of it on the road lol!

gthofan · 05-01-2006, 07:33 PM

it couldnt be blowing bits of cat out the back of the exhaust, the mufflers would catch it!!!!, unless it was the rear muffler that was crumbling.

snypereb · 05-01-2006, 07:37 PM

not sure mate reacons it was blowing out heaps of s@#$!!!!!!!!!!

naughtyfalcon · 05-01-2006, 07:38 PM

Yeah it does, my EA didn't make it home when it started playing up. I t would die and then it would restart but would take a while, then eventually it just wouldn't start. My brother went to it the next day and it started and barely made it home. I guess it cooling down must have helped or something.

snypereb · 05-01-2006, 10:30 PM

Yeah seemed to run better when it was cold and then when it got hot it ran like poo poo!!!!!!!

gthofan · 05-01-2006, 10:34 PM

well did u hear n e thing more about ur car shaun???

snypereb · 05-01-2006, 10:40 PM

Yeah mate this thread is it! He told me the cat was stuffed got a new one just looking if it did any damage to any other parts of the engine had a new coil put in and also a 5th cylinder miss compression is injectors are perfect too thanks to you i may have it back by tomorrow morning hopefully fingers crossed but aint expecting it till saturday!!

Racecraft · 05-01-2006, 10:44 PM

You find alot of the rattles is the shield over the cat, THe cover steel is only pressed on and uses a pressed sheetmetal join to hold it in place, no welds or bolts. If you car is low enough when you scrape it the seam loosens and the covers rattle.

snypereb · 05-01-2006, 10:46 PM

Is it ok to take that cover off?

gthofan · 05-01-2006, 10:47 PM

oh well, but the main thing is u should have it back soon, and hopefully the mechanic doesnt hit the old red rocket (wallet) too bad

Racecraft · 05-01-2006, 10:48 PM

I guess but it'll be 100 times more work than just knocking the guilty area back nice and tight.. That and the floor above it might get a tad warm..

snypereb · 05-01-2006, 10:49 PM
