What This Service Involves
This page gives you a complete picture of the components we replace during a full BMW engine rebuild. We don't just repair the immediate problem — we refresh every part that commonly wears out, ensuring the engine delivers its original performance and reliability.
Our rebuilds are carried out in-house using BMW-specific tooling, with all components sourced to OEM standards or better. Every job includes a full strip-down, inspection, machining where required, and reassembly with new gaskets, seals, bearings, and timing components.
Read our full rebuild checklist for more detail on our inspection process.

Frequently Asked Questions
Do you replace all gaskets and seals on every rebuild?+
Yes. We never reuse old gaskets or seals. Every rebuild includes a full gasket set, with all seals replaced during reassembly.
Are timing chains always replaced?+
On affected engine families (N47/B47, N20/B48, N55/B58), the timing chain, guides, and tensioners are replaced as standard. On engines without known chain issues, we inspect and only replace if wear is found.
Do you replace rod bearings on all engines?+
Rod bearings are replaced on all bottom-end rebuilds regardless of engine type. On performance M-car engines (S54/S55/S58/S63/S65), we use upgraded bearings where available.
What about oil pumps and water pumps?+
Oil pumps are inspected and replaced if worn; oil pump chains are replaced when the timing chain is done. Water pumps are replaced on N55/B58 engines as a known wear item, and otherwise inspected and replaced if needed.
