Hi Mercedes lovers.. I've got an oil leak in my engine
the car is a 300D w123 with Turbo engine From texas

i have replace the
turbo oil return oil ring and gromet
Oil Filter Gasket; Oil Filter Housing to Engine Block

Oil Drain Plug Gasket
Turbocharger Gasket
Valve Cover Gasket
Oil Pan Gasket

And leak will not stop what s the problem ?
i hate some oil leak

This may sound obvious, but you need to find out where it's coming from. Start with where's it's dripping from, then clean that off and see if you can find where it's coming from.

Also, did you check the oil separator in the air cleaner?

Hello aaa
do you have a picture off the oil separator in the air cleaner?
i think thats the problem

some day leaks the car and some day i can t see any leak
i have just claen the engine thit hot water
and now i see nothing leaking

Well I can't find a picture of the exact area, but it's where the separator connects to a tube going to the oil pan. There's a gasket that goes there. Just remove the air cleaner and check out the tube to see if it's covered in oil or something.

If the leak is on the side with the oil filter it can also be the place where the pressure gauge line screws into the filter housing (the plastic lines shrink and leak...the only solution is replacing the line to the gauge). There is also a gasket in the oil filter housing on the side where the line connects...hopefully that was done when the block gasket was done.

Also, mine was leaking at the point where the injector pump connects to the block, but just tightening up the nuts seems to have stopped that one. You really need to pinpoint the location of the leaks in order to properly fix it.

Thanks for reactions
air filter house are clean there is no oil into the filter is dry ans clean

I have heard of folks replacing a gasket/"O" ring in that area, and taking a few tries to get everything lined back up just right.
Good luck.

Remember the engine is behind the fan which is blowing all the time. So any leaks will be blown all over the place. completely clean the engine and diligently check it every couple of days.
The front of the engine has numerous oil seal that need to be checked.

Replacing the 300TD front crankshaft seal and other front of block oil leaks

How can i remove that tube?

__________________

On my '83 300D Turbo, I would remove the air cleaner housing and hoses. Then from underneath, you can see up thru the steering and frt suspension the tube mid way has a bracket with clamp. My clamp was broken and tube flying in the breeze. The bolts attaching this bracket both broke from their welds and I could not remove the nuts from below. I resecure the bracket and with heavy tywraps secured the tube.
I have not cleaned this engine since the starter replacement, other than what I soaked up on my clothes along the way. I hope this helps.

BTW, I spoke to my MB dealership and they have no O-ring listed for this, merely a pressure fit ? ? ? ?

The o-rings are the same ones that fit on the dip stick . The ones on the top any way , I never looked at the bottom but i dont see why they would be any different .
