hey guyz i have a ca18det recently changed the turbo wich i think might be a bit overboosted(stock engine+t25) , did a few runs and suddenly a missfire is taking place before 2000rpm, i also noticed a small lost in power. Checked spark plugs, found some oil, what to do? what could it be? i'm afraid i might need a rebuild as i have an oil leak in the head....
Is there any oil in the inlet manifold pipe?
are you sure its oil and not petrol? eather way if the plugs have been wet with oil or petrol you will have to change them, thats where i would start and if when new plugs are in and you see the slightest miss out of it cut the engine and see if there is still oil-petrol on the plug's?
hope this helps
Have you recently filled it with oil? I did that once with my CA and due to the location of the oil filler you tend to get spillage down the cylinder no 1 coil/sparkplug hole? Would definitely cause a misfire.
