I am set up to have some exhaust work done over the weekend. I have a 95 xlt with a leaking exhaust manifold gasket. The rear bolt is sheared off. I tried to work on it myself last weekend and got brutally dejected by the truck. I am a minor mechanic at best and since the gasket that started this project in the first place is on the passenger side, it looks like a bunch of things will have to be removed to get to the manifold. I tried to get adequate access through the wheel well with the shield removed. That allowed access to the rear bolts, but not enough to do the job. I managed to get one bolt off of each side of where the manifolds connect to a pipe that meets up and then goes to the cat. I'm takin it to the country boy I use when things get to looking like they are a little over my head. My plan is to have him replace both gaskets, then go with a flowmaster super 44. May or may not replace the cat in the process. I will try to figure out how to post a sound bite of the result. By the way, if anyone knows the answer to this one, I would love to know- Where the manifolds link to the pipe im talking about, there seems to be a donut gasket in there or something. Is this right? My guy wasn't sure and I am sure he'll find out soon enough, I was just hoping to save him some time on parts runs if I could deliver all he is gonna need when I drop the truck off today.

yo Larry,

 

Your buddy will be able to get you it all, and if he's a really good pal, at his cost which is really lower than retail prices or via on-line "discount" parts stores.

 

Which sys do you like and Year/ENGINE??

 

I have some SOUND Bite Links in my site @ http://www.broncolinks.com/index.php?index=574

 

enjoy & GL!

yo, your country mech will have the info; such as this;

Exhaust System Parts Break-Out Diagram in 96 5.0L & 5.8L

Source: by Ford via Steve83 (Steve, That dirty old truck) at SuperMotors.net

exhaust5.8l96.jpg

 

NO GASKETS etc that I know of.. some backyd mechs use just chassis grease as a seal...place a thin film around each port. When the manifold gets hot, the grease will bake into a varnish, much like cast iron cookware. The varnish creates an effective seal..some info also by Steve83

 

 

Here is some more info on related items:

1996 F-150, F-250, F-350, F-Super Duty, Bronco and Motorhome Chassis Vehicles Workshop Manual

same as your yr exc for the number of O2 Sensors.. maybe cat converters...

REMOVAL AND INSTALLATION

Exhaust Inlet Pipe

Removal

Remove the muffler (5230),muffler inlet pipe (5A212) and catalytic converter.

Remove exhaust manifold-to-exhaust inlet pipe nuts.

Remove the exhaust inlet pipe (5246) from the vehicle.

Installation

To install, perform the removal procedure in reverse order. Tighten the RH exhaust manifold-to-exhaust inlet pipe nut halfway, tighten the LH nut to 34-46 Nm (25-34 lb-ft) and tighten the RH nut to 34-46 Nm (25-34 lb-ft).

Muffler Inlet Pipe

Removal

Remove the muffler (5230). Refer to Muffler in the Removal and Installation portion of this section.

Remove the U-bolt clamp at the muffler inlet pipe-to-catalytic converter connection.

NOTE: It may be necessary to heat the muffler inlet pipe-to-catalytic converter joint to break it free.

Remove the muffler inlet pipe (5A212) from the vehicle.

Installation

To install, reverse the removal procedure. Tighten the U-bolt clamp to 54-71 Nm (40-52 lb-ft).

---------

Muffler

The exhaust system components are removed, disassembled, assembled and installed using standard tools and procedures. Only remove components to the extent necessary to replace worn or damaged components.

Always refer to the Master Parts Catalog for parts usage and interchangeability before replacing a component part of the exhaust system.

Removal

Remove U-bolt clamp at the muffler input. On Bronco, disconnect flat flange.

Remove the muffler (5230) from the rubber supports at crossmember and frame (5005).

Remove muffler. It may be necessary to heat the muffler/converter joint in order to separate the muffler from the catalytic converter.

Installation

Place muffler in vehicle by sliding it over axle housing.

Position muffler by inserting over the end of the catalytic converter and aligning slot to tab on catalytic converter.

Apply a soap solution to metal support rods on muffler and catalytic converter. Avoid use of oils or silicone since they do not dry and may allow the insulator to slip back off once it is installed.

Force metal support rods through rubber insulators.

Install the U-bolt clamp (U/8500 GVW F-Series/Bronco) and tighten to 54-71 Nm (40-52 lb-ft). On Bronco, install flat flange bolts and tighten to 34-46 Nm (26-34 lb-ft). Tighten nuts sequentially in a criss-cross fashion. Tighten first nut to half torque, then second nut to half torque, then third nut to half-torque, then tighten all nuts to specification.

 

--------------------------------------------------------------------------------

Catalytic Converter, Gasoline Engines

Removal CAUTION: When servicing the exhaust system or removing exhaust components, disconnect all heated exhaust oxygen sensors at the wiring connectors to prevent damage to the sensors and wiring harness.

Raise and support the vehicle.

Remove the muffler (5230) and muffler inlet pipe (5A212) (if applicable).

Disconnect, if applicable, the air inlet tube from the catalytic converter.

Remove the exhaust manifold-to-catalytic converter nuts on all but 5.8L manual transmission (7003) and C-6 automatic transmission Chassis Cab.

Remove the inlet pipe-to-converter nuts on 5.8L manual transmission and C-6 automatic transmission Chassis Cab.

Remove the catalytic converter from the vehicle.

Installation

To install, reverse the removal procedure. Tighten the exhaust manifold-to-catalytic converter or exhaust manifold-to-inlet pipe nuts to 34-46 Nm (25-34 lb-ft).

 

 

--------------------------------------------------------------------------------

 

Exhaust Shields

Catalytic Converter Shields

Removal

Raise and support the vehicle.

Remove the four rear catalytic converter heat shield bolts for the rear catalytic converter heat shield.

Remove the two halves of the rear catalytic converter heat shield from the vehicle.

Remove the two front catalytic converter heat shield bolts and the air inlet tube bracket bolt for the front catalytic converter heat shield.

Remove the front catalytic converter shield from the vehicle.

Installation

NOTE: It is important that all heat shields be reinstalled correctly or heat damage to other components may occur.

Follow the removal procedure in reverse order.

Tighten all fasteners to 22-28 Nm (16-21 lb-ft
