[quote][i]Originally posted by nibnob21[/i] After a further look into things, I think it may be gear lash causing the occasional rattle. Slightly annoying as there's nothing I can do about it, but it's not that bad and only rattles occasionally. It's a fairly common thing on MX5s and is caused when the gearbox isn't put back in quite right if it's had work done on it. A very delicate and precise art refitting them apparently. Once the rattling has started the damage is done, however the good news is that it doesn't actually cause any issues and shouldn't get any worse. Just something I'll have to live with. Came to this conclusion after a bit of research and after taking it for a couple of drives to really try and pin point when the rattle occurs etc. Also, inspecting the gearbox mounting points it's apparent that some work has been done on it in the past as there are some faint marks where the bolts have been tightened up before. So my guess is it just wasn't put back in quite right. Oh well. This therefore obviously means there was nothing wrong with the CAT, but seeing as I've already bought the decat and I needed to sort the blow anyway I set about fitting it today. Bit of PlusGas and much to my surprise and delight the nuts came undone pretty easily! I'm always sceptical when things go to plan and get nervous that something's inevitably going to go wrong :lol: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0374.jpg[/IMG] Prised the CAT out with a spanner: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0375.jpg[/IMG] Sooty deposit on the rear section flange; evidence of the blow: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0376.jpg[/IMG] Sooty CAT flange: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0377.jpg[/IMG] Gasket on the blowing end was fudged: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0378.jpg[/IMG] Decat against old CAT: [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0379.jpg[/IMG] Got the new one bolted on with relative ease. I used M10 x 30mm stainless bolts, which in hindsight may be a little short. Only about one turn of thread is coming out the end of the nuts, hopefully it'll be fine. I just used standard penny washers and regular nuts. Keeping my finger's crossed they don't work loose. [IMG]http://i57.photobucket.com/albums/g230/nibnob21/Eunos%20Roadster/0380.jpg[/IMG] I couldn't manage to get the face of the rear section flange completely clean so I used a small amount of exhaust putty to help it seal. Seems to have worked nicely. The downpipe flange joint I just used the gasket and it seems like it may not have fully sealed, very very minimal though. Still a bit annoying, but I really can't be bothered right now to undo it again to add a bit of putty. Seems to be absolutely zero noise difference, which I was actually slightly disappointed with :lol: I didn't want anything lairy at all, but perhaps just a small noise increase, or hell even just a little burble on overrun would be nice; but no, nothing lol.
