4.6 or 5.4 how to tell?

[Janet Kidwell]

How can you tell the difference between the two other than the obvious cover
on the engine?The reason I ask is we just bought A used Expedition from
Carmax that was supposed to have A 4.6.When we got it home I lifted the hood
and it has on top of the motor 5.4 liter Triton.I dont know if there was A
typo on the paperwork or if some mechanic put on the wrong cover saying 5.4
liter triton.Thanks for any help.
P.s I'm not complaining if it is the larger engine:)

If you look on the engine valve cover on the drivers side there should
be a sticker that states the engine size. Also that long strip of info
that you see when you open the hood will have the engine size in small
writing next to the box that says catalyst on the left hand side.
Furthermore the tenth digit in the vehicle's id # designates the
engine type but I'm unsure of the code.
The bigger engine gives you more power and torque at the expense of a
few miles less per gallon. I would that the power over 2 mpgs.

I believe the 5.4 has a coil pack over each plug and the 4.6 has one
per bank. I'm sure I'll be corrected if I'm wrong <g>.

You can also run the VIN through a carfax, it won't cost you any to find what
engine size!

I can run a carfax report for you, just email me the VIN.

Just look at the rear diff - 8.8" for a 4.6, and a 9.75" for the 5.4

Yeah, and how is someone that doesn't know what a 4.6 or 5.4 looks like
supposed to tell the difference between or identify an axle?
Um...yeah...that's some...helpful advice. :)

Easiest thing to do is look at the EPA sticker under the hood, it will
have the displacement listed there.

Distributor? On a Ford modular v8? Not likely.

I love all this GREAT advice... :)

Not sure if it's true for all years, but if you look at the tranny pan
and there is a drain plug, it's a 4r100 trans which means you got the
5.4L.

What if it's not a factory motor how can I tell the difference between a 4.6 and a 5.4

There are a few ways to tell the difference between a 4.6 and a 5.4 Ford engine:

1. Check the engine code: The engine code can be found on a sticker on the valve cover or on the emissions sticker in the engine bay. The engine code for a 4.6 is typically "4.6L" or "4.6L SOHC" (Single Overhead Cam) and the engine code for a 5.4 is typically "5.4L" or "5.4L SOHC" or "5.4L DOHC" (Dual Overhead Cam).
2. Check the engine size: The 4.6 liter engine is physically smaller than the 5.4 liter engine, so if you are able to visually inspect the engine, you can tell the difference by size. The 4.6 liter engine is around 31 inches long, while the 5.4 liter engine is around 34 inches long.
3. Check the engine's specifications: The 4.6 liter engine typically has a bore of 90mm and a stroke of 90mm, while the 5.4 liter engine typically has a bore of 90mm and a stroke of 105mm.
4. Check the VIN number: The VIN number of the vehicle can also indicate the engine type, check the 8th digit of the VIN number it should be a "W" for a 4.6L engine and "Y" for a 5.4
