oil covered plugs on RS clios is common due to the leaky rocker covers, not much you can do about it other than reseal the rocker!
how water gets down there i have no idea (cleaning geeks engines are industrial, engineering, manly type stuff, hose pipes, APC, whatever else you throw at it = bad!!!)
i agree! i did the mistake on my old saxo vts, i put engine degreaser on the engine, to get all the gunk off, sprayed it lightly with a hose , then a few days later, the engine manager light came on, car engine was violently shaking litually, like it was gonna fly out! called the RAC, and they said it had got water into the cylinder, and it caused it to do that , i soon had a light bulb above my head and thought, yea that was my fault when i sprayed it down, and thought i did a good job avoiding the spark plug holes, but oviously not!
But seriously the spark plugs look fine! and if you do clean your enigne bay!
REMEMBER dont be a fool and hose the engine down lol! i was so dumb!
it sort of looks alright lol
that was the beast back in the days that powerfull 120 bhp! lol
