'05 230K Oil leak from top rear of engine
if you plan on diy, take the engine hook off first i used a 1/4 inch rachect with a 5/16, 12 wall socket, cus the e-10 tork socket i had was for a 3/4 was too big to fit between the fire wall and pump. the pump use the same socket. putting the engine hook back was a pain.
hope this helps you out cholleman,
Thank you very much. I'm going to see about those seals this weekend. I guess i'll have to take a measuring tape to the parts store and see which oil filters have a seal that measures the 3 and 3/4".
Also, if it's not too much trouble, would you mind taking a pic of the location of the pump itself? I looked the other night and wasn't able to find it. Thank you.
I took the part numbers you gave me and searched Mercedes Parts Superstore. With shipping, they came out to ~$12 and saved me a trip to the dealer.


This post was not helpful to either party, the original poster or the new guy. Posting in this older thread proved he was using the search function - something not many do. Had he started his own thread, he would have been told to STFF.
So perhaps you should stop "policing" and start "helping"?

the oil seal ring i use was little short but it strecthed over to fit. make sure the oil filter ring seal is the round kind, not the square one. the pump was easy to put back in. the hook was the hard part.
...and screw that stupid engine hook. i tried using 12point sockets since i didn't have any reverse torx bits. ended up marring the lower bolt that holds the hook on. fortunately it's still possible, though a bit tighter, to get the vacuum pump out. if anyone knows anything about the large o ring/seal that seals the lid to the housing, let me know. and if anyone needs to replace their pump, the part number on the back of the housing is: A 271 230 09 65. worldimpex has them for $210 which is WAY better than the dealer's $750. others might be cheaper, worldimpex was the first google hit.

Not sure where anyone got the idea of $750.

I was told that tranny and engin leak are common on C class. At least, we had tranny gasket replaced twice in the current c class we have.
Dealer will quote it about $750 due to the labor fee. Fortunately, our vehicle is still under 100k warranty. thanks God

Would I need to put the car on a lift to get to the vacuum?
I am pretty mechanically inclined but would love some images or guidance if anyone else has done this DIY before.
Thanks in advance for any assistance/advice.

Why not try it yourself?
I looked up the pump price and I got $159.85
I'm wondering if I should just replace the pump. You know if it came with the seals?
Thanks for your input.

Does anyone know if these 2 seals are interchangeable? I know the MB system says 00 is used up to a certain serial #, then 01 is used after.
My car is supposed to use 00. I replaced it with another 00 and the stupid leak is back. Sigh.
