Overfilling engine with oil

huggy15

I recently done an oil change in my bmw 320d f30 2013. I dipped it after adding the oil and it was up at the max mark. I had noticed recently the engine sounded a tad different than before. I dipped it again yesterday after it sitting overnight and it was reading a few millimetres above the full mark! after driving it i dipped it again and seen there was small air bubbles on the dipstick. I read through a few forums and found out this was a sure sign it had too much oil and wasn't a good sign so I drained out about a half litre, today and it read about half way on the dipstick. I'm going to top it up later and make sure I don't over fill again. I know the engine in the 320d can be susceptible to timing chains going which is worrying. I done about 500 miles with it over filled. just wondering would this cause any lasting damage? and could it contribute to timing possible chain problems ? I listened to the engine while it was idling and it sounds alright, not overly noisy although there is a slight ticking I think but it may just be a normal sound, I'm not sure tbh. could this be the timing chain? any input appreciated. thanks!

If it was only a few mm then I wouldn't worry about it as it wont do any harm. If its now reading half way down the stick then top it up, add 1.4litre and leave it sit for a while to settle and dip again and then add another drop if necessary.

I presume you mean 1/4 of a litre Cee Jay cee.

Buy a vac extractor pump,cheap one,for this problem, and for servicing in future,put your mind at ease

I can understand the use for it when you want to take a bit out in the case of over-filling however but why would you use it specifically for servicing? Why not just drain it via the sump?

They have oil pumps at Lidl now. They do nice and clean job.

Silane

Half way down the stick is fine, the upper line is max, not a target. I'd leave it where it is

Wibbs

A little bit over is probably OK, but too much increases pressure on seals and if it gets to the level where the crank touches the oil, then cavitation occurs causing foaming of the oil and that extra air in the oil will bugger bearings pretty quickly.

pm.

If it's half way leave it alone, no need to fill the oil to the max mark as its just that MAX... Mid way is perfect

Use it every second service as it's quicker and neater. I alternate between sump and the suck vac.
