Engine Rebuilds in Sunbury-on-Thames
When an engine has suffered internal wear or damage, a rebuild can restore it without the uncertainty of a used replacement. It’s major work, so we always diagnose thoroughly before recommending it.
We carry out engine rebuilds in-house, including BMW and Jaguar Land Rover engines.
Rebuild or replace?
The decision depends on the extent of damage, parts availability, the value of the vehicle and the history of the replacement options. We lay out the options and the reasoning so you can decide.
A rebuild typically involves stripping the engine, measuring components, and replacing worn or damaged parts such as bearings, rings, seals, timing components and gaskets.
