Part 2 Now for engine warranties.
Most performance engines come with a warranty similar to ours. These warranty periods are for the builder’s workmanship. In our experience very rarely is a motor covered for some type of workmanship issue, but it can and does happen, as well as them occasionally providing additional support to cover some of the labor. This is entirely at the manufacturers discretion.
Remanufactured motors usually have a 1 year warranty and no mileage restriction. Labor may be partially, or completely covered depending on the company and their policies.
Used motors from JDM suppliers typically have a 30 day start up coverage. This means the motor must be installed within 30 days and they will only provide a replacement if it fails to operate. If a failure occurs, the customer will be responsible for labor for further replacements. This option usually has the lowest overall cost but it also carries the highest risk of additional costs.
Auto recycler / Junk yard motors and parts are usually sold as is with no returns, you own it once purchased. Some of the more credible companies will offer a warranty and also offer additional coverage to extend the warranty on parts and labor costs.
There are extended warranties that are sometimes given or sold with new or used cars. All of them are different. One typical common factor on them is that the owner is responsible for diagnostic work. If it happens to be a failed motor, that means you are paying to have the motor pulled and torn down to find the failed part. This is where they benefit because you have covered half the labor for them.
