Since changing the MSD cap and going to a QF carb with leaner idle and main jets, oil on the spark plug threads is virtually gone. The engine now has about 10,000 miles and burns 1qt./1200 miles. Otherwise it performs well. Is the oil consumption to be expected for these Roush stroker engines? |
Swift, I never thought of that but when my dealer changed the plugs after the carb was replaced by roush the all seemed to have the same bad carbon build up. None worse than the others. But I might check into them jsut in case. From what I heard here and about Roush engines 1pt per 1000miles seems "normal".
