check your spark plugs if they are soaked then try replacing htem first. but check compression aswell as it may be low compression and at your mileage would mean a rebuild of engine.

i have changed the plugs they are new ones, as of the compression it is okey, the problem is that the distrubitor wire itself is what i am talking about, no current is found the two lower cables which is No.1 and No.4.

check resistance of plug wires should be 5000 ohms per foot then if they are ok check for a cracked dist cap. make sure to move wires around while holding volt meter leads to it. then look for crackes in cap or carbon tracing which look like a pencil mark inside it.

there is a crack and a shorted wire which carry currents to those plugs. I have looped the wire, but only one is working except the cracked one which is leaking current. The cylinder to that plug (No. 4) is always flooded with oil, can that failed plug cause oil to flow into that cylinder? Even with plug adaptor the plug is always soaked. Please i want to know

fix the crack and shorted wire if you don't you'll continue to get your oil/gas soaked plug. also check engine compression.

is it really certain that if i replace the coil wire and plugs the oil will stop comming to the cylinder?

part of it is because the cylinder isn't firing tha tis why I told you to check compression it cold be bad valve seals or something else but until you do what I asked for you to do it is a mute point to keep asking the same question over and over. I have no further suggestions for you.
