Featured Engine: 5.4L Ford Triton


The Ford Triton engine made its debut in 1997 and was offered in many pick up, van and SUV applications. The Triton family of engines included the 4.6L and 5.4L V8 engines, as well as the 6.8L V10 engine. This featured 2004 Ford F150 5.4 Triton was released in 2004, is the 5.4L size and features 3 valves per cylinder for a total of 24 valves. This 5.4 liter Ford crate engine uses Variable Valve Timing (VVT) to attempt to improve performance, fuel economy and/or emissions.  

Tri Star remanufactured 5.4 liter Ford crate engines are built to meet or exceed OEM standards and our backed by our standard 3 year, unlimited mileage nationwide warranty (private use applications). For total peace of mind you can also upgrade to our 'No Fault' Warranty Supplement, call for details. All Tri Star's remanufactured Ford truck engines incorporate the latest updates to correct original design flaws - Click here for the product bulletin outlining the updates of Tri Star remanufactured 5.4L engines. Tri Star engines are remanufactured, not rebuilt, for the most reliable and durable engines available. Tri Star remanufactured 5.4L Triton engines are completely remanufactured including machining the block, crank, connecting rods and cylinder heads, and assembled with new or remanufactured parts. Rebuilt 5.4L Ford 3 valve Triton engines will only correct the issue with the "core" engine used as raw material, but will typically not include any other machining or remanufacturing on the rest of the engine or have any updates performed. Used engines incorporate no updates and are extremely susceptible to failure due to mileage already being on the engine with questionable maintenance records. Used and rebuilt 5.4L Triton engines are inferior, do not correct any of the original equipment design flaws and typically have very limited or pro-rated warranties. When shopping be sure to ask if you're getting a used, rebuilt 5.4L Triton engine or a 100% remanufactured 5.4L engine.


Be sure to use our online lookup or call our engine experts to ensure proper fitment for your application. Don't worry, the Vehicle Identification Number (VIN) from your vehicle is required at time of order as well.

The 5.4L 3 valve Triton engine is notoriously known for valvetrain noise (rattling or ticking), noises under acceleration from the cam phasers and/or timing components, spark plug failure and issues with low oil pressure. Tri Star remanufactured 5.4L engines address these most common failure points in the remanufacturing process to provide the most durable and dependable engines.

Valvetrain noise, low oil pressure, VVT codes •New O.E. VVT actuators (cam gears) installed. These are extremely crucial to the 5.4L 3v engine but some competitors reuse cam gears or replace them with inferior aftermarket alternatives.
•Cam journals are machined and engine is assembled with cam bearings for tighter clearances.
•Updated high flow oil pump from Melling.
•VVT solenoid housing screens replaced 100%.
•VVT solenoid housing checked for straightness.
Leaking timing cover and/or oil pan •Tri Star includes the timing cover and oil pan installed on this 2004 Ford F150 5.4 Triton engine. Timing covers are checked and machined for straightness to ensure a good seal. All engines are simulation tested and black light checked for leaks during testing.
Spark plug thread issues •All spark plug threads are 100% inspected. Any threads that are damaged are replaced with TIME-SERT® inserts, the OE approved method.
Premature bearing failure or engine knocking •Blocks and cranks are completely remanufactured to exact tolerances utilizing CNC machining equipment
•Crankshafts are micro-polished to extend bearing life. Unlike some competitors, the tape used for micro-polishing cranks at Tri Star is only used once and in only one direction. Reusing tape back and forth can cause fine metal particles to become impregnated in the journal and cause premature failure.
•Tri Star 5.4L long blocks include the oil pan and pickup tube installed to avoid contamination issues. Some competitors offer the engine without the pickup tube installed which risks it being exposed to dirt/debris that will plug the pickup screen.
Head gasket failures or leaking head gaskets •Multi-Layer Steel (MLS) head gaskets are used which resist heat and avoid head gasket failures.
•Compression height on the pistons is reduced to maintain factory compression ratio specifications.
•Both the block and cylinder heads are precision machined to exact specifications.



  • Graphite coated hypereutectic pistons resist scuffing and damage to heat much better than factory aluminum pistons
  • Moly piston rings and steel compression rings reduce friction and cylinder wall wear to extend the life of the 2004 Ford F150 5.4 Triton engine
  • Fel-Pro® rear main seals protect against heat and leaks
  • Connecting rods are honed (both the little and big ends) to ensure uniformity, and bent rods are scrapped (some competitors will bend rods back into place)
  • Chrome plated valve stems resist scuffing and heat for greater durability
  • Soda blasting aluminum components provides a visually 'like new' raw material without the risk of contaminating the 5.4 liter Ford crate engine (some competitors blast with other abrasive materials which can become stuck in the 2004 Ford F150 5.4 Triton engine and cause the new engine to fail)
  • Every engine is 100% simulation tested very thoroughly by skilled technicians. Engines are checked for good compression, oil pressure, and black light checked for any leaks before packaging
  • Engines are provided with a written warranty which clearly outlines coverages. Unlike some competitors, Tri Star warranties are not 'pro-rated' which decrease your coverage over time
  • Engines are shipped in plastic totes with simple core return instructions provided to make returning cores extremely simple
  • Excellent product support technicians aren't just order takers, they are knowledgeable customer service experts
  • You're buying your remanufactured Triton 5.4L direct from the manufacturer so you know you aren't dealing with a middle man for increased costs and headaches for warranty, core returns and technical assistance
