nerf99 0 Posted March 17, 2008 Report Share Posted March 17, 2008 i've just been digging around underneath my 96 vr6 as i noticed the exhaust burbling on the way home. there appears to be gas venting from a small spiggot or hole at the back end of the cat on drivers side. is something supposed to be connected to this (such as a sensor) or has some sort of cap fallen off- hence the burbling. i've got to get the cat motd by the end of the month so i guess the venting needs to be sorted out- the noise is horrible anywayanyone got any ideas. i'm going to be replacing the system from the cat back anyway as the centre muffler has blown. will i need to add a new cat in with this?

thegoth 5 Posted March 17, 2008 Report Share Posted March 17, 2008 The cats are drilled for two lamda sensors, but the VR only uses one, the front one. The back hole is normally filled with a bolt, which often rusts away. If the thread has gone as well simply get a garage to weld over the hole. Link to post Share on other sites
nerf99 0 Posted March 17, 2008 Author Report Share Posted March 17, 2008 cheers for the advice. should be a quick fix. i'll look to see if there are any threads left to take a bolt otherwise its the welding gear Link to post Share on other sites
