Many of our clients are automotive repair professionals such as new and used car dealerships, independent auto repair shops, vintage automobile restoration and customization shops. However, we also service hundreds of retail clients who want top-quality engine repairs and rebuilds – and that’s who this page of our site is really meant for. Here, we’ll give you the basics of what’s involved in a complete engine overhaul from removal to re-installation. In most cases, engine rebuilds are ready for pickup between 2-3 business days from the day your vehicle arrives. If we need to remove & reinstall the engine, then it will be ready for pickup between 5-10 business days.

Our complete engine remanufacturing process includes the following

1) Removal of the engine assembly for teardown.

All external components removed and inspected for excessive wear.
