whats the beat way of getting rid of the oil inside my engine???
please NO wisecracks
ive run it on fully synth for 70k and it had started to leak out of every oriface so i changed to vaux semi synth.
the engine used to be nice and clean on the inside
2k miles later
its all black with like tar deposit everywhere in the rocker box
also my cam is now pitted in places and when i start the engine it takes nearly twice as long for the oil light to go out
i will stick some fully synth back in but whats the best way to clean as much 5hite out?
