I notice there are little oil leak under the car between the back engine and the transmission joint. I suspect this is the
reason for the engine oil lost. (about 3
liters for every 1500km with no white smoke from the exhaust)
Is this a common problem for this
model ? and What are the part need to be replace ? BTW, Can this be a week end task ?
Thanks in advance

Also, I have never seen a leak that is a drop on a driveway cause a oil loss.

I think it is the transmission oil (red),
but I can't notice any transmission oil
lost from the dipstick. However, the engine
oil lost is significant. (as I described
earlier). Can the engine oil leak from
the engine and transmission joint ?
I really to have fix this because it is
expensive to refill the engine oil.
Thanks.

If the drop that you are seeing is red it ATF not engine oil and will have not effect on the engine oil loss. Yes engine oil can leak from this area as can transmission oil.
A few drops of oil on the ground does not account for the amount of oil loss that you are reporting. Engine is most likely burning the oil. If you think that the cost of oil is expensive then you probaly do not want to know the cost of the repairs that may be required.

well,If the engine oil can leak from same
area, I would like to get it confirm and
rectify.
Repair is one time cost but refill is
forever. Just wonder, if the engine is
burning the oil, How can I confirm that ?
Is it true I should see some smoke from the exhaust ? In my case, there isn;t any smoke.
Many Thanks.

If the oil is coming in through the
headgasket, you run the risk of a
hydrolock which will probably bend
a connecting rod and cause other
problems - none of which are cheap.

I recommend finding the cause of the
oil usage. I am not a mechanic but
I would think that a thorough compression
test would be a good start.

My 300SD uses 0 quarts between 2500-mile
changes. At one time (about $8,500 ago)
it used 1 quart per 1,000, then 1 quart per
700 miles, etc.

As I stated before a few drops of oil does not account for the loss of 3.0l per 1500Km
If you were leaking this much oil the entire undercarrige of you car would be dripping wet and the exhaust would be covered with oil makeing a very bad burnt oil odor.
As far as diag. of this is concerned The first order of buisnes is to remove the sparkplugs and inspect for the pressence of oil residue on the plugs. Then procede with a compression test and a cylinder leakage test. the CLT is much more accurate than the compression test. If nothing is discovered with these test then have the clyinders inspected with a bore scope. It is possible that all you need is valve guide seals. If the compression test and the CLT show up negitive and there is oil residue on the spark plugs I would replace these seals.

Whoa guys. Don't scare him to death! :)
I have an 89 190E 2.0 that uses a whole schwack of oil. I freaked when I first got it, but then I looked in the owners manual. Depending on how much the engine is stressed (and in hilly Pennsylvania, the poor little 2.0 is VERY stressed), "normal" oil consumption can be up to 1.5 liters per 1000km. My car uses about a quart per 600 miles, so I'm well within "normal". Even though I use so much oil, the car doesn't smoke. This is not to say that oil consumption is *desirable*... but it is, according to my owner's manual, acceptable.

altan 06-16-1999 11:36 AM

Well, Can someone confirm on the Jason
statement ? Is this applicable to 190E only ?
BTW, how much engine oil do I need to refill from min to max level as indicated on the dipstick ? ~1 liter ?
Thank for all the reply.

I send it for inpection today, and
problem seem to be due to some harden
valve seal and and some play at the valve
guide. However, my mechanic proceed to
replace all the valve seal and would like
to monitor the oil consumption again.
Anyway, If problem persist, then I have
no choice but to replace all the valve and valve guide.
Thanks Corky.

I have a 1990 190E 2.6. Had the same problem with oil loss. Took the car to the mechanic and he replaced the valve seals. He said the old ones were too hard already. Cost was $180. Shop was not MB, but mechanic is familiar with MB and BMW. Oil loss was reduced, but did not disappear completely. Hope this helps you.

altan 07-30-1999 11:57 AM

Thanks JMike, Mine is the same, the
consumption reduce but not disappear
totally. Anyway, I will live with it
since no top up require until the
next service, ie every 5000-6000km.
