Exhaust Manifold

So a shop told me I had a cracked manifold. The same shop replaced my bad catalytic coverters. I'm no expert so I'm not sure if its supposed to have a gap between the cats and maifold. Need help! Lol

Its got a flange between it. Basically a big metal gasket that is pressed together.
The manifold cracks because the ac drip line drops on it. Common problem.
The 4 catalytic converters usually go out between 100,000 and 150,000 miles.

i didn't think my old v6 had a gasket there and didn't think my new one had one either....just went out and took a pic



the "cracked manifold" could just be a crappy gasket they put in there when they installed the new converter...when the ball and socket should be enough to keep leaks from forming. could be a legit cracked manifold but the a/c drips on the passenger side...that pic is the driver side

If it is cracked at the flange, would that require replacing the manifold? Because I was told that I have a crack at my flange and I wanted to fix it myself but I want to know what I need

Could probably be welded..but like I said that gasket could just be leaking since it normally doesn't have one there. Although if it comes to repairing a manifold you may consider just saving for headers and swapping since it has to come out anyways.

This is a post within a post about my manifold as well my problem is how to i tighten the manifold tighter at the flange, or is it suppose to move at the flange. Or what does that mean when it's able to move

Tighten it. It should fit tight. Figure out what size the nut and bolt is and tighten them with a wrench
