N14 Timing Chain - MINI's Biggest Problem
If you own a 2007-2010 MINI Cooper S with the N14 engine, you need to know about the timing chain issue. This is the most serious problem in MINI history.
The symptoms: Rattling noise on cold startup (the "death rattle"), check engine light for camshaft position codes, rough running, or sudden loss of power. If ignored, the timing chain stretches, jumps teeth, and destroys valves and pistons.
Why it happens: BMW used a defective timing chain tensioner in N14 engines. The tensioner fails to maintain proper chain tension. As the chain stretches, it rattles and eventually jumps timing causing catastrophic engine damage.
Our solution: We replace the entire timing chain system with upgraded components - improved tensioner, guides, rails, and chain. This is a 10-14 hour job that requires removing the front of the engine. Do it before the engine fails and save thousands.
We've performed hundreds of N14 timing chains. We know this repair inside and out. Don't wait until the chain jumps - address the death rattle immediately.
