Venatus 2 Report post Posted May 25, 2008 I had a look at some spark plug reading charts, but I couldnt find anything that resembles what mine looked like 3 weeks ago, put new ones in anyway, will have a look tomorrow at the condition that theyre in... Anyway, to me, something looks severely wrong, and it could be the cause of my 6km per litre fuel consumption. The oil there is just from a rocker cover leak I think, its just pooled in the hole for the spark plug and doesnt actually get into the cylinder as far as I know...Im pretty sure my smoky engine is buggered rings.... But anyway, could someone help me out and give me an idea of what this means? Thanks. Quote Share this post Link to post Share on other sites

While you're at it,. make sure your air filter is good - replace if necessary. As for oil smoke, generally that always means you have some repair work to do - it can only be piston rings, valve seals, or cracked head gasket. Off the top of my head. Someone else will probbaly tell you what else to check. Quote Share this post Link to post Share on other sites
