hi, i changed my spark plugs today and noticed the two plugs nearest the battery looked like this! any ideas why? i recently had the big end replaced and had to run the engine in again- would this have anything to do with it??
funny you should say that. i've replaced my rocker cover, the gasket and the plug seals today as the original gasket was cracked and leaking a bit of oil. maybe i've already fixed the problem then!
