Hi All,
My Father drives a 2018 Alfa Romero Giulia 2.2JTDm 180 with 40k on the clock. The car has had annual oil changes with a 0w20 ACEA C5 oil. We are having issues with oil pooling in the intake.
Our mechanic has condemmed the turbo, but I'm not convinced that a well serviced car with 40k on the clock and a reasonably easy life is suffering with any sort of turbo failure. The doesn't seem to be any oil coming from the turbo itself, the turbine spins freely and there's no play.
In the intake hose between the airbox and the turbo there is an oil breather of some sort that comes from the side of the block. I suspect more than likely this is where the oil is coming from. Couple that with the angle of the drive the car gets parked on where the airbox is the lowest point, oil is finding it's way back into the airbox.
My current plan is to run with a thicker oil to hopefully reduce evaporation slightly, install a catch can in the oil breather pipework and get my Father to stop parking on the driveway for a period of time to see if that cures the issue.
Suprisingly, the MAF currently seems unaffected but I think it would be wise to clean it while doing all this work.
I'm just looking for some opinions, maybe something I might be missing or a better way of checking that it isn't the turbo leaking? Any advice welcomed here.
