I am here today as I am concerned about E46 325CI Convertible 2001, It seems to be using alot of oil. I have had the vehicle around 7 months and seem to be topping up 1.5 litres of oil every 3 weeks.
I have had the rocker cover gasket changed as it was leaking slightly and that all seems fine now.
I have read about the cvv? the crank ventilation valve and if this gets clogged up, that it can lead to high oil consumption.
Also I am due to have 2 of my coil packs changed this weekend as on a recent diagnostics, the machine stated that cylinder 3 & 5 are misfiring. could this be a reason for high oil consumption?
If someone could please advise as the car is using alot of oil.
