Hi Tank 34,
I considered myself fortunate to bought the car from one very careful Datin lady driver who also religiously had her car serviced by AB. Very tip top if not, mint condition.
Dr Meng suggest me to change the tank as he told me it is a life item i.e not subjected to normal wear and tear but count by number of years!
I had to buy his words as I found out by knocking the tank with my fingers,the tank reverberate distinctlively.This show the plastic had become brittle unlike the japanese made which is made from a more resilient plastic material.
Better replace it than sorry.
There are a few things here which I would like to share with all our BMW brudders here and correct me if I am wrong and to save our hard earned monies.
Dr Meng sometime gave me benefit of doubt but he may be right, depends how you look at it.He said my crankcase is leaking oil and even jack up the car to show .HE suggest me to change the gasket.
All I can see is some wetness around the lower crankcase.I think it is normal cos the gasket is made from aluminium alloy not impregnated with a rubber seal around it. Sealing is done by sandwich the metal gasket between the crankcase and lower case sump.
This is purely a metal to metal contact and different metals have different coefficient rate of expansion and contraction. Overtime,oil will just seep thru.
There are many definition of leaks i.e patches,seeping,wetness or running leaks.I done a very simple experiment to confirmed the oil leak. .Just thoroughly clean up your car porch floor of oil stain,then park your car on it overnight and the next morning, look at the floor for any tell tale signs of oil.So far, mine is o.k.and save me Rm600 for the gasket. Another way is to check your dipstick every 5k miles and see how much oil you need to add.
BMW recommend to change the engine oil at every 25k! I think not in our kind of Hot and Humid climate. I prefer to change oil at every 12k and use Castrol magnatec semi syn to do the job. A 4 litre Castrol full syn cos Rm150! but the semi
syn cos somewhere from Rm70. After all I am going to change oil at 12k,no need to pay Rm300 for the full syn.
BTW,do you know why BMW recommend to change oil at every 25K?
This is applicable In Germany where Labour charges are count by the hours excluding parts. Less workshop visit means less money spend.
Also changing the engine to a new one is better than fixing cos the new engine come from around Euro 1k depend on model? Here, it would cos us a whopping Rm40k for a new engine!
I learn this from a German Gentleman.
