Automatic transmission 1996 F-150 pick up with a single exhaust system: "Your right manifold is needing replacing. That's what our engine guy came up with."
Is the "engine guy" talking out the wrong orifice, or is this plausible?
Further Questions will help narrow down the answer.
1) Intake Manifold or Exhaust Manifold?
2) How many cylinders in the engine, and in what arrangement? (Inline or Vee?)
The fact that there is a single exhaust pipe just means that the exhaust stream joins into one pipe (normally, for a Vee configuration engine, the output from the exhaust manifolds (one for each side of the engine) will combine before the catalytic converter, then single-pipe from there.
So, yes, having to replace the right manifold is plausible, and leads me to the exhaust system, since intake manifolds are really only seen on carbureted engine.
