hey guys, my car is slowly leaking its way dry. and need some advise quick.1) power steering leaking , mechanic suggested/quoted steering overhaul rm480 and only 90% guarantee there wont be a leak as internal compartment are worn out etc. assuming the price quote for service kit + labour2) oil leak from valve head cover - has change the valve gasket last year october and now leaking again. mechanic said the valve cover bengkok redi, possibly need to replace. could this be possible , what the material of the head valve cover made of ? and any price that i'm looking at ?? what i'm suspecting is too much engine oil in the system. as my earlier service records, it was written 7.7L of engine oil. where service manual says 6.5L. i have brought it up during my last service and he actually poured in 7.7L to make it to full level in the dip stick. and the mechanic said its normal. so curious could this be the reason, too much pressure build up on the oil and leaking through the valve cover . and how much oil do you guys use? please advise guys. thankse36 325i (A)
