Review on Dorman 674-223 Nissan Exhaust Manifold: Passenger Side Compatibility for Select Models by Jeff Bourke

Revainrating 2 out of 5

I would not recommend that.

This manifold is leaking where it contacted the rear exhaust port of the cylinder head. When I took it off to check for a problem, I found that it wasn't properly formed or machined so there was a gap that the gasket couldn't fill. I had to reinstall it because I needed the car, but even after trying a different gasket and trying to re-tighten the manifold once it was warm, it was still leaking. I'm not sure what my next step will be, but I'm uncomfortable trying a different Dorman manifold on this truck. I think I'll stay away from Dorman collectors in the future.

Pros
  • Manifold and Parts
Cons
  • I am concerned about this
