We offer complete rebuild services for all Jeep and Jeep Utility vehicles from 1941 through 1976. Our process starts with ensuring the block is checked for cracks using three separate tests; first, we pressure test, to see if any cracks may be just below the surface. Then, we clean all valve ports, deck and passenger side for magnafluxing. If it passes these tests, we send the block out for synthetic media blasting. With the block free of paint, rust and grease, we magnaflux again. From there, we begin machining and assigning parts to the build. We don’t have a flat cost for engine rebuilds due to various factors, such as:

• What components you are providing. Please note! Cores in exchange: cylinder head, block, crankshaft, cam, connecting rods, clutch plate and disk, carburetor, distributor, manifold assembly, generator (alternator), starter, flywheel.

• Type of block required

• What components we’re rebuilding (carburetor, distributor, generator, starter, etc.)

• Whether your engine block is usable or if TJL needs to provide one

There are numerous other factors that go into correctly rebuilding these engines, so please include your telephone number in your inquiry.

Good to Know

All estimates include itemized parts recommended along with an approximate time to complete the work. If unseen issues arise while in progress, we require written authorization before we proceed. All services require a percentage (to be determined) of the estimate before we start your project. If you take delivery in Minnesota, sales tax will be charged accordingly.

Core return or charge

If a new engine block, transmission or transfer case is required, a charge for the block, case or crankshaft is required. The core return must be something we can use for future rebuilds. See above for return core requirements.

If a core is not provided to TJL, the core charge is equal to half the value of the replacement core. Example: if a professionally checked engine block from TJL is $2,000, we will charge an additional $500 if no core is provided. We don't sell blocks or cases which look-good-but-don't-worry-about it. Instead we provide the best tested engines around. The engine block is the foundation of your restoration. Cutting corners will only cost you more later.

Core Return Requirements:

• All rod & main bearing caps are present AND are specific to that block

• Maximum bore diameter does not exceed 60 over standard

• No heavy scoring, or rust pitting in cylinder walls, cracks or broken castings

• Acceptable engine cores: October - November 1941 Willys Americar, Ford GPW, Willys MB, CJ2A, CJ3A, CJ3B and any stock standard Jeep specific engine used on Jeep and Jeep Utility vehicles. We do not accept a CJ5 V6 as a core for a rebuilt CJ2A engine, it must be the same family of engine.
