carl0s Posted February 8, 2007 Share Posted February 8, 2007 I just had a brainwave and decided that since I'm doing nothing, I might hop under the car and fit my 1st DeCat. I want to know if that's likely to be possible though. Does the 1st decat pipe bolt right up towards the turbos, or is it fairly flat horizontal under the car? I don't want to jack the car up and throw my far-too-small overalls on if it's going to be a PITA. GF's mum's hubbie has a ramp in his garage but we're both too busy ATM for me to get over there (it's in Wales..) Quote Link to comment Share on other sites More sharing options...
uk-rich Posted February 8, 2007 Share Posted February 8, 2007 if the 3 bolts in the turbo flange come out its easy, if they snap it can be a ball ache! Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 hmm. I could do with an under-car picture showing the two CATs in place really, so I can see what I'm replacing before I get under there. Quote Link to comment Share on other sites More sharing options...
uk-rich Posted February 8, 2007 Share Posted February 8, 2007 no pic, but there is one flange with two bolts at the bottom, one at the top with 3 (the tricky ones) not the weather for this job Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 but it doesn't go up towards the engine does it? It's pretty much straight horizontal in-line with the exhaust, right? Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 not the weather for this job 'tis snowing a bit but I have a decent ground sheet. Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 Just jacked the car up and took a look. Unless I'm being a bit thick, the first cat goes right up towards the engine and isn't even very visable. The end of it comes out just above the main crossmember/jacking point. It also has what looks like an O2 sensor bunged into it. The decat pipe I have bought doesn't have a hole for the O2 sensor. Is something not right?

carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 Come on Ian (Shytot). I can see you looking. What's the answer? Quote Link to comment Share on other sites More sharing options...
Ian Ian Posted February 8, 2007 Share Posted February 8, 2007 Hey up Carlo,s ...........you need a LONG extension for the Three bolts connecting the cat pipe and the Turbo exhaust bit thing ( technical talk there ) they will be Tight as !! so be careful not to snap or strip the bolts etc ........mine came off ok ............you can see where you want to be by looking down under the turbo,s from the top just as an idea to how far you have to reach up from underneath if that makes sence LOL You coming to Masgrat on Monday ?? Cheers Ian Quote Link to comment Share on other sites More sharing options...
Ian Ian Posted February 8, 2007 Share Posted February 8, 2007 Come on Ian (Shytot). I can see you looking. What's the answer? LOL and to add yes the O2 sencer is connected to it too just unbolt and put it on your decat pipe Cheers Ian Quote Link to comment Share on other sites More sharing options...

Cheers Ian D'oh. So it's as I feared - right up to where the turbos are. The second decat would have been a piece of piss. Is the "turbo exhaust bit thing" (that'll be the flexible pipe bit then) threaded or something, so you don't have to get someone to hold a nut on the other end? Masgrat.. quite possibly I'm working in Ilkley on Monday which is a bit of a bitch to get back from, so have to see how it pans out. Would be nice to go though and see some more fancy cars and friendly people again Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 So you just tie the o2 sensor out of the way - it doens't need to be fitted into the decat? Quote Link to comment Share on other sites More sharing options...
Ian Ian Posted February 8, 2007 Share Posted February 8, 2007 So you just tie the o2 sensor out of the way - it doens't need to be fitted into the decat? You dont need to have someone above "holding the nut" its three bolts that hold it on and threaded so no problems there ................dunno about the O2 sensor mine had a bracket thing ( more tech talk ! ) for mine, so cant help you there matey ...but im sure someone will be along to clarify if you need it ? Great stuff will be good if you can make it think theres going to be a good turn out Cheers Ian Quote Link to comment Share on other sites More sharing options...
kosmic Posted February 8, 2007 Share Posted February 8, 2007 Is the "turbo exhaust bit thing" (that'll be the flexible pipe bit then) threaded or something, so you don't have to get someone to hold a nut on the other end? No it has studs which go into the turbo downpipe so all you have to do is take off the 3 nuts. No need for anyone/thing to hold the other side. Id use some penetrating fluid first to and then try and loosen them as you may snap or round them and then your buggered. Quote Link to comment Share on other sites More sharing options...
kosmic Posted February 8, 2007 Share Posted February 8, 2007 So you just tie the o2 sensor out of the way - it doens't need to be fitted into the decat? That will be the Temperature sensor in the 2nd cat your talking about. When you replace that cat, just tie it up out of the way, it isnt needed.

I bet it's going to be a bastard to get the bolts lined up and back in again.. hmm. i've got a lovely bendy extension bar though.. http://www2.css-networks.com/bendy.jpg Quote Link to comment Share on other sites More sharing options...

Was gonna suggest that, unless you have a neck and arms like E.T. its best if you get it up on a ramp just in case. Oh and your gonna need a bigger bar/rachet then that.

When you replace that cat, just tie it up out of the way, it isnt needed. It definately looks like it's in the first cat to me.. sorry about the picture quality. http://www2.css-networks.com/sensor.jpg I really need to get another decent mini-camera.

kosmic Posted February 8, 2007 Share Posted February 8, 2007 No that is the temp sensor, the O2 sensor is further up on the turbo downpipe. Yours is a j-spec right? Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 OK, I used a light this time. That's in the first cat isn't it? http://www2.css-networks.com/sensor2.jpg Quote Link to comment Share on other sites More sharing options...

I'm not doubting that it's a temp sensor, I'm just wondering how that can be the second cat.. Quote Link to comment Share on other sites More sharing options...
kosmic Posted February 8, 2007 Share Posted February 8, 2007 Thats the first cat alright, that does look like the temp probe though, just checked and yes i have mine in the shed (1st cat) with the temp probe in it, my bad. it isnt needed so just tie it up out of the way Quote Link to comment Share on other sites More sharing options...
carl0s Posted February 8, 2007 Author Share Posted February 8, 2007 OK, car firmly back on the ground now This job can wait 'til next weekend when I can get to ramp, at least I have a better idea what's involved now. Quote Link to comment Share on other sites More sharing options...

Just make sure you soak the 3 nuts up the top with plenty of penetrating fluid first Quote Link to comment Share on other sites More sharing options...
