MINI model and engine fitment

MINI model Chassis Approximate years Engine
One and Cooper hatchback R50 2001–2006 W10 petrol
Cooper S hatchback R53 2002–2006 W11B16A supercharged petrol
One and Cooper convertible R52 2004–2008 W10 petrol

Relevant engine codes are W10B14A, W10B16A and W11B16A. Check your egnine code or confirm the OE references against your VIN before ordering.

This kit does not cover later N-series engines including N14B16A. Those engines use different camshaft parts.

Inspecting camshaft and rocker wear

A persistent top-end ticking noise is a reason to inspect the valve train. With the rocker cover removed check the cam lobes and each rocker roller for pitting, scoring or uneven wear. Look for a worn-down lobe and check that every roller turns freely.

Noise alone does not confirm a failed camshaft. The timing-chain tensioner and other valve train components can also cause noise. If the lobes are sound but a rocker is noisy or damaged have the complete valve train inspected before deciding which parts to replace.

Check the oil supply before fitting new parts

A replacement camshaft will not fix an oil supply problem. If the old lobes or rocker rollers are badly marked ask the mechanic to check the oil level and supply along with the rocker shafts and their oil passages. Inspect the camshaft bearing surfaces and remove any metal debris before assembly.

On an R53 the standard oil pressure warning switch doesnt provide a measured pressure reading through a normal OBD scan. Suspected low oil pressure needs checking with a suitable gauge. A blocked passage or low pressure can damage the replacement camshaft and rockers as well.
