thats weird then as i would have expected it to be smoking a little.

just have a look under at the sump and see if its wet with oil. my focus has been weeping a bit of oil from the rocker cover for months, gets the engine and sump coverd but never leaves drips on the drive as it doesn't leak that bad. i've sorted that now mind by switching to the silvertop rocker cover which uses a much better gasket imo.
