Post subject: | Oil leak next to the spark plug |
Hi guys, I'm giving my Paso 87 a full Maintenance Service. However I noticed i have a leak next to the spark plug of the vertical cylinder. A few centimeters to the right of the spark plug is a small screw. At this screw i have an oil leak. I noticed that the horizontal cylinder has the same screw next to the spark plug. What's the use of this screw ? Can't find the answer in the manual. Somehow the screw has to block the oil of coming out of the cylinder. :thumbdown: The nasty thing is that the screw is so thightly that i can't get it loose. I sprayed some creaping oil (WD-40) on it. Creaping Oil, is that english ? :confused: Is there at the end of the screw a contra-nut perhaps ? Does anybody know ? Do I have to dismantle the upper cylinderhead before i can loosen the screw. :screwy: This must be a leak that other paso drivers have had. greetz, ![]() Steven |

![]() That kind of oil is often called 'penetrating oil' in English. The screw is probably to stop the end of an oilway that was drilled into the head after it was cast. It is probably best not to remove it. You could clean around it with a solvent, and then seal it with a high-temperature compound of some sort. |

Hi Skins, :thumbup: You say best not to remove the screw but i have the impression that this screw has already been changed. The screw on the horizontal cylinder is dark brown, maybe because it takes a lot of dirt from the front wheel. The colour of the screw on the vertical cylinder is gold. I must check if it really gold, if so the screw comes out, whatever it takes. :funny: Unfortunately it's will be a compound of iron or copper ? I strongly believe that it's possible to change the screw. But i would like to hear if any other paso drivers already done this. If so, how did they do it ? :confused: |

It is an oilway blanking screw and would have been locked in place with a strong thread locking compound at the factory. The compound had probably crystalised over time, hence the leak, but it will still be extremely difficult to remove so I suggest you take Skins' advice and seal over the top with some high temperature silicone compound if it proves difficult to shift. This is what I have done as there was no way mine was going to come out. |
