I did a search and came up with someone here saying all 5.4 f250s 99-04 are the 2V. I'm looking at buying an 04 250 with the 5.4 that the owner says is a 3V. Is that possible? The truck isn't local to me, would a simple picture of the motor tell for sure?

From what I understand the 3V is undersirable because of a special tool for spark plugs. I read that as expensive? Is that right? What are the other advantages/disadvantages 2V vs. 3V?

Thanks

 

A 2004MY 5.4L V8 or 6.8L V10 is 2V.

 

IMHO 3V is the way to go. More power and better fuel mileage.

Not sure about the special spark plug tool you are talking about though.

 

3v 5.4L 300hp / 365 tq 2v 260hp/ 345? tq. IIRC.

To clear things up, the 3V 5.4L up until nov '07 (2008 MY) had weird looking LONG spark plugs that could become stuck in the head. Upon removal at the ford recommended 100k interval, the 2 piece design spark plugs would break, and you would pull out only half of the plug. The Tool your talking about extracts the lower half of the plug by threading into the lower half of the plug. there is little risk in any pieces falling into the engine, and NO RISK of loosing the lower part into the engine due to it's tapered design. There are one piece plugs manufactured by Champion ( still two peice, but welded, not crimped like the MC plugs.) These plugs do not seem to break upon removal, but can still be stuck until the carbon ( the main sticking reason) is broke loose. Solvents help this, and there is a very good TSB on the removal of the stock plugs with specific directions on how to extract the broken plugs. Engine and/or head removal is not needed except in the most extreme circumstances. Dealership charges can be signficant if not under warranty. Some report that even on a truck in which the dealer broke some changing the plugs, the customer was charged an extra fee for extraction. warranty or no warranty.

Most owners of the 3V recommend plug replacement at 30K to avoid the stuck plug problem. It has made a difference for some, other it didn't matter. Following the TSB IS still highly recommended.

Hope this helps

 

The 5.4L 3V engine first appeared in the 2004 F150. The 5.4L 2V engine was used in the 2004 Super Duties. It wasn't until 2005 that the 5.4L 3V appeared in the Super Duties.
