Case of My E90 (320i) Disappearing Oil - 1 liter every 2000++km!!

Re: Case of My E90 (320i) Disappearing Oil - 1 liter every 2000++km!!

hi Guys;
Just share my experience, I have oil leak problem too, fixed one place and another place leak again. Done all the fixes on external leaking and still my engine consumed oil every one month of my normal routine drive. I used to go to a famous BMWS in Alex and they don't really offer good service decided to switch to one at level 2 AMK Autopoint.
The WS owner Mr. Lim told me that 10 out of 10 cars got this problem (mine is E60 520) of oil consumption problem around 100k mileage. Decided to bite the bullet and give it a try to do a top overhaul today. His advise is not to switch to thinker oil as it may damage the engine in the long run. I think if I do it right the first time with the right WS when I encountered oil leakage, I could have saved a lot of money.

Should not rush into changing valves just because someone else describe
same symptom as yours
Better to get ws to trouble shoot than to self-prescribe the fix
Most likely reasons how oil consumption varies:
1.Even when new, some engines will consume more oil than others.
In passenger cars, an oil use of 0.1-0.3% of the fuel consumption is seen as normal.
Even within the same series of engines, variations are present and about 20% of
the engines have a higher or lower oil consumption than average.

2.A long list of mechanical problems may lead to oil being used up,
such as wear and damage of seals and gasket, the bearings, cylinders,
ring grooves, connecting rods, etc.

3.Driving style has a huge impact on oil consumption.
Frequent acceleration and driving at high RPM will inevitably
increase both oil and fuel consumption.

4.Failure to respect the oil drain interval will lead to oil being used up faster.
Dirty oil will block the thin oil passages and some oil will remain trapped there,
instead of flowing back to the sump.

5.Inappropriate viscosity grade: too thin oils with lower than recommended
viscosity will tend to enter the combustion chamber easier and get burnt
together with the fuel.

6.Similar to a lower-than needed oil viscosity, too high engine temperature
will also result in thinner oil and increased consumption due to burning.

So how much did they charge you for top over haul?

How many days down time?

If you oil level is yo-yoing, when it should not fluctuate no matter when you check it, it's time to change the oil sensor.

Cost around $120-150 for that part.

But to change this part which is at the bottom of your oil pan, you have to drain out the engine oil, which means oil sensor + oil change together.

I just did an oil change about 1500km ago,now the engine oil level seems unstable.After a long drive (

Hi bro seanskype,

The sloshing around is true, but it doesn't affect the oil level reading.

If i am not mistaken, our oil sensor uses thermal sensing i.e. after oil is heated up, it detects the volume of oil in the engine.

A layer of sludge on the oil sensor may cause it to fluctuate as it's unable to do it's job properly.

Hence, changing to a new oil sensor will help. This part typically can fail between 50-100k interval so it's a wear and tear item as well.
Do it with your next oil change. You will find your oil level staying the same, no matter what time or when you check it (i.e. after it warms up of course).

Yup. When you start driving, the engine oil gets sloshed all over the place and hence the readings are no longer as accurate.

hi , supposed to be 2 full days. I sent in late afternoon yesterday, the boss told me he will start working in the night for my car as he got other cars lined up. Called him up today and he said most likely late evening can get my car. Cheers.

Two days sounds reasonable,by the way how much did they charge?Can pm me workshop name please?

Can pm me the ws and charges as well.thanks bro

Hi the ws EuroAuto at AMK Autopoint level 2, goggle and you should get the details. call Mr. Lim 97567671.
Haha, damage or salvage cost is around $1.6k. plus new oil and misc oil filter, air filter about $1.85k.
I have gone round in circle looking for a good reliable ws but end up spending more $$ until I found this ws. if your car mileage is close to 100k, don't waste money doing piece mail job or change one valve at a time. In the end, still need to do overhaul as wear n tear of the engine is unavoidable, just like once in a while we need to spring clean our house.

Can pm me the ws and charges as well.thanks bro

I need to top up 1 litre of engine oil every 6500km. No white smoke and no oil stain at the exhaust. Call mr lim of Euroauto to enquire abt top overhaul but he say N46 engine is only 50% chance to remedy to solve the engine oil shortage.Only N46N engine is 100% problem solve after doing the top overhaul. N46 engine need to do full overhaul

Is the oil getting out through the PCV ?

Re: Case of My E90 (320i) Disappearing Oil - 1 liter every 2000++km!!

hi yes I overheard Mr Lim told one of the owner (320i) the same thing. He is quite trustworthy. No point to tell you 100% if it is only 50%. Than you have to pay double to solve the problem. suggest you go down to take a look at the WS and find out more.

Re: Case of My E90 (320i) Disappearing Oil - 1 liter every 2000++km!!

I'm experiencing oil leak and I need to top up around 1000km to 1500km. A workshop recommended changing the seals and since labour is already included, he also suggested replacing a motor, which will also improve engine performance. I'm unclear if its the valvetronic motor.

I'm wondering if anyone has experience replacing the valvetronic motor and what's the function of this?

Thanks...

Re: Case of My E90 (320i) Disappearing Oil - 1 liter every 2000++km!!

I have done this before by the other famous BMWS in Alexandra.
Don't waste your money doing piece mail job like what I did before. Call EuroAuto.

Hello William, does EuroAuto sponsor you? Why not get it registered as site sponsor?










Cheeeeeeeeeeeeeeerrrsssss...........

Euroauto is a nick or a place or something that can be eaten?

Sounds like a WS, not sure about its background though.

What I am saying, is that in the past, many of us were newcomers once and some of us had been misled by "word of mouth" or "third party" referrals, and got our rides or previous rides f'ked up bad as a result of f'ked up workshops that professed to be or were "recommended" as BMW experts. I have had one f'ked up "BMW expert" dealer WS (obviously not a site sponsor) pour 10, yes TEN, bloody liters of EO in my ride before because the mechs couldn't find a dipstick.

What I am not saying, is whether EuroAuto is a good or bad workshop. But if it is truly a good BMW specialist workshop, perhaps more forummers will benefit if it becomes registered properly as a site sponsor and stands up to scrutiny by more pairs of eyes.

Major jobs I go back to PML.
Gearbox, radiators, water hoses, there are enough good WS experienced in these and I can trust them with major repairs and replacement. Otherwise I go back to PML for them to solve. $$$ spent I can ZZZ
