Engine Oil Top Up Issue

[astroboy]

If valve seal rosak, you will be emitting white smoke in your tail pipe. If serious, u will have a wet tail pipe.

...

On another note. Recently i follow my friend to Naza service centre as he had to overhaul his Naza Ria due to overheat. So while we were there, i noticed that Petronas also supplies engine oil to Naza and it comes in 4L packaging which was written Petronas Syntium 3000 5w-30 and at the back there was no BMW LL-98. So now i'm confuse.

1) Does Petronas make the same oil "Syntium 3000 5w-30" with 2 different packaging?
2) Our BMW dealers use "Syntium 3000 5w-30" without the BMW LL-98 specifications?
3) Petronas short change us without the BMW LL-98 certifications.

Cheers

BMW SC are using special grade LongLife oil and is supplied in drum/bulk. So far non of the SC grade oil is supplied in retail 4L pack, except the 1L pack BMW oil (OEM Castrol). The Syntium sold by SC is Syntium 5000 LL (if not mistaken) and not available in retail pack. Even their Castrol LL or Helix LL is not available off the shelf.

And Mobil 1has lots of fake out there. Be careful!

i dun think so, means it got nothing to do with valve seal now. Mind sharing with me when u service, u pour in how many litre of engine oil and when it reach how many km u top up again. my is just a merely of 2.3k km and about 4 weeks from last service. Using Mobil 1.

my car is 2004 (dec) CKD lifestyle E46(N46B20) and millage is 81300km now. Oil sensor is ok, wife told me dipstick show oil is slight above min level on the indicator, basing on this how much i need to top up? what is the possible caused of it, would changing valve seal solve this problem?

Thanx for the reply

I am not comfortable with the way your N46 consume engine oil.

I too pour in 4L into my N46 during intermediate oil change but +1L only lit after more than 8k km.

If u have a dipstick, then forget about the OBC oil level sensor, use your dipstick as a guide. Pour little bit, then check la. If not enough, then pour more la. Never drive JDM before meh?

Did the workshop pour in all 4L?

Seriously, I have seen workshop bill the customer for oil change but did not do anything to the car..

wah like that means my car really makan engine oil kao kao......2.3k and ask for engine oil again....did the workshop pour in 4L is a very good question......sien....got to deal with this problem....

Any idea for change of valve seal and do the top overhaul cost how much? anyone here do it before? some feedback would be good.

Engine oil won't just vanish like that. Especially we are talking about 1L in 2.3k km. Must look for signs like wet car park, wet tail pipe, wet engine body, oily spark plugs, even your coolant, for signs of seepage into you coolant thru worn gasket.

If I were you, I will top up the oil and see what happen next. And since you have a limited time warranty coverage, perhaps seek a 2nd workshop opinion so if there's a chance to exploit the warranty, you can take advantage of it.

Did you check you dipstick after the recent oil change? If your workshop short change u and end up you ask them to do top overhaul, sounds like a profitable business model..

I had to top up when I was using Castrol 0w30.. then at next service changed to 5w40 and problem solved.

1L for 2.3k km? The Mobil 1 is definitely not 0w-30, should be SAE40 if not mistaken.

i call up my service advisor from M1 , jeffrey , he told me this is common for N46 valvetronic engine. Unless i change my engine valve seal, and to do so, i need to spend about 5k+ and he told me even the new valvetronic engine also got makan engine oil issue. if i dunwan to do so, just buy engine oil and top up and he say, is definitely engine oil consume and not the leaking. This is manufacturing defect. Anyone heard of this before? Please share more,feel like asking wife to sent car for check up.

My friend just bought a new 523i less than a year ago during the promotion period also faced the same problem. I saw someone compalined about the same issue in NST Cars Bikes and Trucks section. It seemed like a design fault. Not a manufacturing defect.

Latest update from my case, i have check it with 3 workshop , all the three confirm need to change the valve seal and also the piston ring. And need to do a top overhaul. Guess what, since there are going to remove the engine cover so i go n have a look, my engine got no sludge, condition superb, thanx to previous owner on every 10k service.

since i still got warranty , i bring the car back to the second hand car dealer to claims warranty. Bla bla bla, trying to tell me this is usual lar, whatever la...bla bla bla. Again, got to thanx to this website and also the forumer for contributing information for me so that i wont buy the idea of need to top up engine oil one, this car all like that one even the new 5 series. All valvetronic like that one. And i got him fixed it for me to change the engine valve seal and also the piston ring, in a way which is doing the top overhaul. and also change me a new oil filter and new fully synthetic oil.

finally the secondhand car dealer call me, ask me to top up some money, telling me need to cover this n cover that, most important i think his commission got cut, so i dunwan him to do anything funny, i tell him, i will pay him 500 for the labour fees and also considering i wan things to be done perfectly for me. he is happy and i m happy.

By the way , the second hand car dealer sent my car to LB smart Auto service. is at cheras there, Big industrial lot, lot of big car, got bimmer, rolls royce , porsh there. i bet they are good. Anyone of you service or repair ur car there before?

and i just make friend with the secondhand car dealer service advisor, he told me to replace and valve seal,piston ring and do the engine top overhaul only cost them only 2.5k++. All walk in customer price would be double up, M1 quote me 5k++, just now i ask that guy LB auto, he told me 4K++ close to 5k. i told the service advisor, if next time i wan to repair anything, ask him to arrange for me, i will pay him some arrangement fee. he is ok

i will update after i got my car back in next few days and will drive it and update, i ask them to put in 5w 40 fully syn for me. will check my engine oil and update frequently, hope my experience will help other forumer as well. Thank you.

Don't forget to run in those new piston ring, while u are at it, see any pot and polish necessary or not. Remember, intake manifold no need too smooth.. :wink:

Actually mineral oil is more suitable for run-in the piston ring. Then drain them after 1k km. Think about it or seek 2nd opinion.. :wink:

They never tell me need to run in, so, i need to do so? since i m not changing engine block or piston, only change the piston ring, valve seal, casket and also engine top overhaul. advise would be good. Thx.

Alo! Your piston is not rubbing the cylinder sleeve la. Its the piston ring in between that's soak up all the friction and to keep the gap sealed preventing crank case oil from splashing up into the combustion chamber. The new piston rings need to seat in properly and the process is called "run-in" or "break-in" ..

Check the manual. The break in instruction is to keep rpm below 3k (if not mistaken) and below 160kph for 2k km.. :wink:

The space between the two marks on the dipstick corresponds to approx. 1.1 US quarts (1 liter). I excerpt it from the Owner's Manual

found this, and already sent my car to hospitalised, final confirmation is valve seal, piston ring need to change, considered a top overhaul.

HI THERE FRIEND,

I know it is an annoying problem. Almost everyday i used to check my engine oil dipstick. It used to drop every 2 days to half the dipstick. I bought my car last year in august. Noticed this engine low levels after a month of driving . white smoke used to puff out. I wanted to solve this problem immediately. Went to my friend who is BMW expert workshop.His name is Albert Pang at Pandan Indah. He open up the top cover and I saw my engine was full of bloody dreaded SLUDGE. Previous owner never change his oil we concluded. Was like ur maid cook with the same oil for a week and u can imagine what color and stuff the oil would be. So i decided to do full overhaul and found out that my crankshaft , crankshaft bearing , conrod and lots of other stuff was full of this thick sludge and it was gone , spoil and caputs! U know what i mean...Oil passages was all clogged up with this black sludge too... my piston and block were all no use to me already.... so the option was to change all the parts of get a 2nd hand engine.... My mechanic said cheaper to get a 2nd hand import N42 engine from Japan ... It cost me rm 6500 and his labor was rm 1200 and my mechanic found one for me and took him just 2 weeks to get it done...... I also change new timing chain and tensioner with valve seals......... Wala, its all brand new now .... Now its running on Motul fully synthetic oil 10-40w as my mechanic recommended ....5000km and today i just check the dipstick after 3 months of this new engine .... Not one single drop of oil lost, bro. It is still at the top level , MAX!
Thats my story .... If u need further info from me ... feel free to call me at 016-9227788... My name is Malvin. U take care k. All the best in what u decide to do .
