Exhaust issue

Hi, A mechanic was telling me I needed a new RH manifold for my car. One day the smoke was coming out of the hood bad so I decided to check myself. I notice there was a hole next to the oxygen sensor where the smoking was coming from. I did a bit of research and have seen that there is something (hose?) That is connected to RH manifold when searching for other Lexus manifolds of the same year. My guess is I'm missing that part since thats where I saw the smoke coming from. I don't know what that part is called or where it connects to from the other side or if there is a certain procedure in connecting it back on. Please help!

Any chance you can post a photo of it? It sounds like you're describing a rusted off emissions tube. Depending on how it was attached, it might be less expensive to replace the entire manifold rather than trying to repair it. On some, that tube is pressed in, and once the manifold gets rusty the new tube won't stay in place. Some designs use a screwed-in threaded fitting. Again that rust can destroy the threads.

For many applications there are repair kits for this type of problem but we would have to see what it looks like first. The goal is to find the most reliable and permanent repair, not one that will result in more problems in the near future.
