Replaced exhaust manifolds, hear another exhaust leak
I replaced both exhaust manifolds on my '00 (stock exhaust). The originals had some leaks at the primaries where they're welded to the flange. Visible soot marks and I had the audible exhaust tick.
I now hear an exhaust tick but appears to be coming from underneath. I believe it's the collectors at the mid pipe. Has anyone had issues with getting it to seal at the ball connection to the manifolds? The studs at the manifolds have been re-torqued after a heat cycle and the collector nuts are all tightened down. I made sure to tighten them evenly when I had it all lined up. I'm thinking about dropping the mid pipe entirely now and checking the mating surfaces and maybe even taking a sanding wheel to the collectors at the mid pipe to make sure it's clean. Then maybe put a coating of anti seize on there. Also, just an observation, I'm a bit surprised that the factory mid-pipe(Y pipe) doesn't have any exhaust hangers. I would think this causes quite a bit of stress on those manifolds being that they and the rear portion catback connection are all that support this heavy pipe w/ 4 cats. |
Someone correct me if I'm wrong but isn't there a hanger at the trans mount?

Anyway when I get to it, I plan on dropping it down again and cleaning/sanding the collector areas really good and maybe using some anti seize on the mating surfaces for good measure. |
