zetec turbo breather system problem
hi hoping that some one can help. i have an 1800 zetec turbo fiesta and my crank seal on the belt side keeps leaking, ive changed it twice and its just started leaking again. im thinking it must be a crankcase preasure problem, im running the frst inlet manifold with an uprated alloy breather and the small pipe that runs from inlet to breather has a 1 way valve and im unsure which way its ment to be and if this could be my problem. i also have smoke coming out the exhaust with a hint of blue which is obviously oil but the head is brand new and the compression test is reading 140 across the board so bottem end seems good and the turbo has done less than 50 miles, so im stumped any help would be greatly appreciated thanks
