Posts: 2230  | oily deposit around the sparks. hi guys,i have just recieved a set of ngk iridium spark plugs,a new set of leads,a distributor cap and rotor arm. why? cos i have noticed the power drop when running on lpg and the vehicle started to stutter on take off. after looking into the matter i was told by shakir who also runs on lpg that the leads are prone to damage and the sparks fitted to the 110 motor are not the best for lpg.anyhow i checked the leads one evening when the engine was running and saw small sparks coming off the 3'rd lead! at least i will have a piece of imnd when the electrical parts are renewed,as i guess 18 years of use does take its toll... now back to the topic heading: i was looking over the engine at the leads and sparks to see how easy they come off and noticed an oily wetness around the sparks.what could have caused it  rgds hus  | |

When topping up oil some gets spilled some time it will run over a hot engine quickly and into the recesses, most will evoporate or burn off but you may get a little residue, before you attempt the plug change I will post a photo of that rear plug on a engine that is out so you can see the difficulty, here is a little tip,before removing old plugs use air gun and brake cleaner to clean all the crap out of recesses, wear saftey glasses when doing this. when fitting a plug turn anti clock wise until you feel it click over the start of the thread , then turm it slowly clockwise and you should avoid cross dressing. apply ample copper slip to thread first ensure you do not contaminate spark surface. remember sequence of leads if you dont you will find each one numbered in tiny digits on the cap. good luck Huss | |

Posts: 2230 | RE: oily deposit around the sparks. changed the leads and sparks(NGK IRIDIUMS) yesterday and took the G for a run lastnight.the hesitant pull off at the lights and lack of aceleration on kick down have gone infact the the response of the rev counter when hitting the pedal in neutral is unreal  the difference in performance of petrol and lpg was very obvious before but now the difference is almost zero. i have an airport run tomorrow and will really see the improvement. | |
