The 4.6, 5.4 and 6.8 Triton engines have been used extensively in such popular applications as the Ford Explorer and Expedition, E Series vans and F Series trucks, Explorer Sport Trac, Mustang, Crown Vic as well as the Lincoln Mark LT, Town Car and Navigator.

This Triton engine family is susceptible to issues with low oil pressure, spark plugs, general and valve train noise, engine rattle, knocking and ticking noises, noise under acceleration, timing components and the cam phaser. JASPER has addressed these issues to improve the reliability of this engine family.

Please view our Ford Triton product information below to learn more about some of the quality processes we perform to this engine family.

JASPER remanufacturing advantages include:

100% torque-plate honing of the engine block, using a torque plate and specially designed ARP2000® head bolts.

Decreased piston-to-bore tolerances for improved ring sealing.
Cam clearances are held to a tighter JASPER® standard through the use of CNC boring machines.

100% installation of a high-volume oil pump, which includes a higher-pressure relief valve spring and a rigid backing plate for improved oil pressure on 3-valve VVT V8 engines.

Verification and machining of 3-valve VVT solenoid housings for straightness.

VVT solenoid housing screen undergoes a thorough ultrasonic and pass-through wash process to verify proper oil flow to actuators.

100% NEW installation of the latest design camshaft actuator VVT solenoids (excludes VVT Delete engine option).

Installation of new or remanufactured cam gear actuators on 3-valve VVT engines.
MLS head gaskets

Block and head surfaced to 50-150 Rz.

100% new head bolts

Piston compression height reduced to maintain O.E. compression ratios.
100% inspection of all threads.

Damaged threads are replaced with TIME-SERTS®, which allow for increased thread engagement.


JASPER oil tolerances are more precise than O.E.

Micro-polished crank
100% upgrade of early 4.6 DOHC oil pump and screen to high-volume pump and large oil tube screen.
JASPER offers VVT Delete as an option for the 5.4 engine.
