well for start your crank can hit the oil if the level is too high, as it spins at at least few thousand RPM it can cause severe damage, and if the level was way to high i dont think you would be even able to start/turn over the engine...

nope it should be ok, as long as you dont hear any strange sounds with hood open at idle...if you do dont drive it. how much did you put it? as car manual the area between lower and upper mark on the dipstick should be almost 2 quarts (less than 2 litres) so if it was low and they put in 2 litres you should be ok...but if it was like 3L thats bit too much....

yeh you see, if you "just" stopped the engine and did the reading it was showing low but then all the oil settled and on top of the you got extra 2 quarts and thats too much....
Do one more reading with oil warm but car has been sitting for at least 5 minutes.... but either way it should never be over max. mark

If you have excesive.. more than 5 liters say.. that will cause probs.. but below that it will not be a prob..The M series has a double baffle in the crank area to minimise crank splash so you might find the engine will burn a lot of oil giving you poor performance and fouled plugs.. there might also be leakage past your valve seals. However.. getting back to the right level and driving for 10 miles or so will return it to normal.

Good day,

I have had my oil and filter replaced yesterday, but I do think that the guy has overfilled it a bit.
Can this cause a "klanking" sound?
I plan to take my car in to a MB Specialist this week, and have them just extract some to the correct level.

In the meantime, is it safe to drive the occasional trip to town?

Today when I ran the car I saw whitish smoke that wasn't there before? Could this be from oil over fill?

It was also cold and rainy, could it just be steam?

Regards,

Erich

Too much oil can cause it to "foam" as the crankshaft spins causing problems with oil pump pick up

Peter's statement is precise information; but in addition Mercedes recommends that the "ideal" oil level is halfway( or somewhere) between the upper and lower marks on the dipstick(read that in a Mercedes bulletin on AllData).

So.. sorry to bump an old thread, but I drained the oil from my ML 320 and and proceeded to fill with 5 quarts of oil. Well, turns out this was way too much and after driving for about 10 minutes the car started to make a weird clunking sound at higher revs, and it was holding gears a lot longer before shifting up... 1st gear to 2nd was okay, but would take a while from 2nd to 3rd and 3rd to 4th....

Whats the chances I've done some real damage here? :(

I did read the dipstick after fitting it, and it was over the red line by a fair bit, but I thought the engine just had to run through the oil, so I didn't give much credit to it, seeing as I emptied the oil already.... and I read that the engine thats 8.5 quarts. I only put 5... I was stupid.

There wasn't much oil when I drained... lucky to be 3 quarts.. It seemed strange to me why more oil wasnt removed when I drained it. Stupidly I paid no attention to it.


Can you guys give me any reassurance? I can't drain oil and test the car until tomorrow morning so I'm a bit worried.

I only drove it for 20 minutes.

Are you sure you drained the motor oil and not something else? If you put in 5 that was not enough. If you added 5 to a full level then way too much. Did you drain the transmission by accident?

I guess it's possible I drained the transmission... but the oil was black, not red...

I drained the plug at the front of the motor... ITs a hex key..

It was on the left side (if u were sitting in the car) under the engine..

I always had the idea that the transmission sump was further towards the middle of the chassis?

God, I hope I didn't do that..

It would explain the car not shifting though... shit.

The oil drain bolt takes a socket and is center of car in front of the front wheels. If you drained a hex key behind the front wheels it probably the transmission pan. Transmission pan has a stamped design and is a flat pan where my oil pan is deep. My car is a 94 so I have 1 oil pan. Some have an upper and lower pan. A picture of which pan you drained would help solve the question.

Fuck.. dude I think you're right.

Fuck.. I hope I haven't done anything too major...

My god I am such a fucking idiot..

I just checked, I saw the oil sump... I must've added a shit load of oil to it.. Even though my dash was reading low oil for about a week.. I hope I haven't fucked it up too much.

And the tranmission, it was the sump that was lowest to the engine with a vertical straight down inset hex... shit :(

This is possibly the worst combination of things to do..

No transmission oil.. engine over revvs..

Whilst way too much oil... frothing up.

Drain the oil and change the filter. Add 8 quarts of oil. Then I would drop the trans pan and replace filter and inspect for particles. Clean trans pan and reinstall. Drain the torque converter and add 9 quarts of Dexron 3 transmission fluid. Easy 1-2 hour job today taking your time. Just drive up ramps needed and of course tools and supplies.

I just hope the engine is okay after... The noise didn't sound good, hope it subsides. I'm pretty sure the transmission will be okay as it was just a short drive. Shit :(

if you can take a picture of the thing you drained (actually where you drained it from) it would help alot. When the transmission fluid is old on the 722.6 tranny it will look like old motor oil (like the first time I saw mine i thought it was oil)

also the fluid amount would be about 4quarts if its the transmission (hence the reason its called a 4quart flush sometimes it can be anywhere from 3-5 quarts needed) low transmission fluid is bad for the clutch packs but 20 minute driving is not too bad I drove mine for a while because of a leak and it would do some weird shifts and once fluid was at the right level it went back to normal

This thread just gave me horrible flashbacks.

A few years ago I accidentally overfilled my Lotus and it caused unbelievable problems, requiring a $15k engine rebuild. Never made that mistake again. Didn't even overfill it by a significant amount either.
