K-series engine.
Loss of power/misfire - valve sticking
Range:
111,114, New 214/216/200 Vi, New 414/416, metro 1.1/1.4 XW 214/414
Problem:
Loss of power and misfire is likely to occur while the engine is warming up but can also occur when it's
warm and while the engine is at various RPM. Likely to occur on cars that have done more the 5000 miles.
Cause:
Journeys that don't allow the car to warm up to optimum operating temperature and shorter journeys that
never allow the car to reach high RPM are a prime cause. The valve stems particularly the exhaust ones
become clogged with carbon deposits.
Action:
New carbon break valves should be fitted to replace the old. These new valve stems have a slight narrowing
to allow the small amount of carbon deposit which occur naturally to form without fouling

c'est quoi le carbon break valves
