Did all that was suggested but no luck. Had an oil leak--in fact oil was being forced up the dipstick housing. Read an unrelated posting about crankcase pressure & tried the solution--i.e removing the oil filler cap, taped on cloth & ran around for awhile. Definitely have crank pressure!! Think Jay could be onto something, i.e pipes blocked in/to & from turbo. Need to sort crank pressure first. Where does breather run from/to? Easiest way to clean?
