  • <h4 class="dechead">On One Hand: Cost to Rebuild

    The cost to rebuild an engine varies depending on the type and complexity of the engine, as well as whether the parts being reused are within recommended clearance tolerances. Take the popular Chevrolet 350ci V8 as an example. Costs can break down similar to this: Rebuild kit: $200 to $600 (depending on parts included) Labor to clean and machine to tolerances: $300 to $600 Labor to reassemble the engine: $200 to $500 Labor for the engine remove and reinstall: $400 to $500 Assuming no other incremental parts are required, between $1,100 and $2,200 has been spent. It is not possible to completely know if additional parts will be needed.

    On the Other: Cost to Replace

    An alternative is to replace the engine with a new or remanufactured engine assembly. This may be a more cost-effective solution. For example, you will have a much closer idea of what your parts expense will be. It's reasonable to replace the existing engine with a long block assembly. The long block will have all of the major components of the engine, and all that is required is to transfer small parts and accessories to the new assembly. A typical new long block from GM can be installed, and all the pre-existing parts and accessories can be reused for little more than the cost for a complete rebuild. Add to this the fact that the parts are new and covered by a factory warranty, and you may have an easy choice.

    Bottom Line

    The unknown variable when rebuilding an engine is always going to be unexpected parts replacement and labor costs. As with anything, higher-quality parts and work cost more. It may be more expensive than estimated. To zero in more precisely on a total cost to renew an auto engine, the option of replacing the engine with a new or remanufactured assembly becomes a reasonable consideration.
