jasper Posted February 11, 2011 Share Posted February 11, 2011 What makes you think you need an engine rebuild? How do you know "oil" is on the plugs? How many spark plugs are involved? Which ones? What are the compression numbers? What color is the smoke out of the tailpipe? Get the idea??? Quote Link to comment Share on other sites More sharing options...

Which ones? What are the compression numbers? What color is the smoke out of the tailpipe? Get the idea??? The plugs are black thats why i think its oil. All six plugs are black. I dont know the compression. Its got a kind of blue look to the smoke and when i rev it up it shoots black soot out spots on the ground.

jasper Posted February 12, 2011 Share Posted February 12, 2011 It sounds like overfueling/running rich. What engine/ fuel system do you have? What is the history on the car? Milage? Pictures? Quote Link to comment Share on other sites More sharing options...

Pictures? Its the stock l28 77 280z. And its the stock Fuel system that came with the car. I bought the car from the frist owner about six mouths ago. The lady i bought it from said it has ony run over once so if thats true it has 160,000 on the engine. I planed on rebuiled it and geting rid of the few rust spots but if i have to do the engine stuff frist. I toke pics of my engine and of a spark plug. And the one with the black on the concret wall is back up to it and the exhust left that on the wall. Quote Link to comment Share on other sites More sharing options...
Cheesecakepiebar Posted February 12, 2011 Share Posted February 12, 2011 The plugs are indicating that it is running on the rich side, but are not oil fouled. I would recommend doing a compression test (with the engine warm), but just for information sake. Quote Link to comment Share on other sites More sharing options...
