Ford Fiesta 1.25. 02 reg.Oil inside rocker cover?

In the plug depressions. The motor is not burning oil. No blue smoke.Wheres the oil coming from.

Leaking rocker cover oil seal. It's only a simple seal, not a high pressure gasket, and a little oil is leaking and collecting in those depressions.

There's supposed to be oil in the rocker cover. It is there to lubricate the valve gear. If the oil is getting to the plug recesses you need to fit a new rocker cover seal.

If its not losing oil then it will be spilt oil or grease melting on the rocker cover and surrounding areas when the engine gets hot it melts and runs to the lowest point
nothing to worry about just clean it off

You may have an oil leak at rocker cover oil pan seals may be leaking oil line also check radiator to see if oil is in rad

Hi so is oil getting on to the spark plugs inside the engine.
if this is the case it is very worn and needs a re-bore which would suggest it needs a new engine. Worn out.
