THE VENERABLE JEEP 4.0 LITER INLINE-6 ENGINE HAS POWERED MILLIONS OF JEEPS, INCLUDING CJs, YJs, WRANGLERS, CHEROKEES AND WAGONEERS.  THE 4.0 DELIVERS ADEQUATE HORSEPOWER FROM THE FACTORY, BUT MANY OFF-ROAD DRIVERS WANT MORE HORSEPOWER & TORQUE TO CONQUER CHALLENGING TERRAIN, WHICH MEANS THESE ENGINES ARE OFTEN BUILT AND MODIFIED.  THE JEEP 4.0, OR 242-CI IS AFFORDABLE, ABUNDANT, EXCEPTIONALLY DURABLE, AND MANY CONSIDER IT ONE OF THE BEST 4X4 OFF-ROAD ENGINES.

WITH MILLIONS OF JEEP 4.0 ENGINES IN THE MARKETPLACE (THAT ARE SUBJECTED TO EXTREME USE), MANY OF THESE ENGINES REQUIRE A REBUILD.  IN ADDITION, MANY OWNERS WANT TO EXTRACT MORE TORQUE AND HORSEPOWER FROM THEIR 4.0 ENGINES SO THESE ENGINES ARE ALSO MODIFIED.  THIS COMPLETE AND AUTHORITATIVE  GUIDE COVERS THE ENGINE REBUILD AND BUILD-UP PROCESS FROM BEGINNING TO END.  "JEEP 4.0 ENGINES"  IS THE ESSENTIAL GUIDE FOR AN AT-HOME MECHANIC TO PERFORM A PROFESSIONAL-CALIBER REBUILD OR A HIGH-PERFORMANCE BUILD-UP.
