Our BMW Engine Rebuild Process
When your BMW engine requires a full rebuild, we strip it down to the bare block and carry out a detailed inspection of every component. Worn or damaged items — such as pistons, bearings, gaskets, and timing components — are replaced with brand-new, high-quality equivalents.
Our experienced engineers then reassemble the engine using precision tools, working to exact manufacturer tolerances. Before handover, we run thorough bench testing and on-vehicle checks to ensure your BMW delivers the performance, reliability, and smoothness you expect.

Essential Vehicle Servicing & Warranty Validation
We stand behind our work. Every reconditioned engine undergoes rigorous testing before it leaves our workshop, ensuring optimal performance and durability.
To maintain peak performance, and keep the warranty validated, two compulsory services are essential, ensuring your engine stays in top condition. These services include:
-
2 months or 500 miles (whichever comes first)– A basic engine check, oil and filter change. Remove covers, check gaskets and seals that have been replaced and any snags from the rebuild can be assessed.
-
Service Costs vary dependent on vehicle and engine size.
-
-
6 month or 6,000 miles (whichever comes first) – A thorough engine assessment, full service with oil filter, air filter, and spark plugs (if petrol) replaced, system diagnostics, and performance inspection.
After the warranty period is complete, we recommend a service every 6 months or 6,000 miles to correctly maintain your reconditioned engine.
These checks help keep your reconditioned engine running smoothly and efficiently.

Good communication throughout process. Work completed within time frame and when extra parts needed replacing, the cost was communicated before proceeding and the reason clearly explained. Good friendly staff. Engine now running sweet after 500 mile service. The aftercare and 12 month warranty was what made me choose these guys. All going well so far.Posted on Neil TaylorTrustindex verifies that the original source of the review is Google.

Thankyou to James and Charlie for all the hard work in get my Mini back up and running.Posted on Emma HodgesTrustindex verifies that the original source of the review is Google. We took our Kia Sportage to Reconditioned Engines fearing the worst as the engine wouldn't start. They managed to locate the issue, a busted crank pulley. They diagnosed and fiixed the problem within three days. Every member of staff we spoke to was very helpful and communicative. When it came to paying, they only charged us cost price for the parts and did not charge for unnecessary work as they only billed us for three hours labour. We couldn't be more impressed with their service and quality of their work. We highly recommend them!Posted on Justin TalbotTrustindex verifies that the original source of the review is Google. Excellent service, great communication. Recommended.Posted on Joe WrightTrustindex verifies that the original source of the review is Google. We've had 3 engines reconditioned by these guys.
