I saw white steam or smoke coming from under the bonnet just as I was
leaving the dual carriageway. This stopped, then the temperature gauge
started to rise toward and into the red. Before I came to a halt the
"Check Oil" warning light came on and the engine started sounding
uneven.

I checked the engine oil and water and both seemed to be at the
required level. The car has been  serviced regularly since 1998 but is
it possible that there is a blocked oil filter?. Can anyone please
tell me what the cause is likely to be. I Have someone who can
probably make an affordable repair but it will help if I can find the
cause first.
