Question on First Oil Change on a 240D

[airfoill]

I just purchased my first 240D (and my first M-B for that matter) and will pick it up Thursday. It is a 1982 year model with 103K miles on it.

I also bought a Haynes manual at the local auto parts store because I would like to change the engine oil when I do pick it up. I noticed in the Haynes manual that after you drain the engine oil from the oil pan and replace the plug, you also remove the filter cartidge, which is what I expect. What I do not know is whether some residual oil remains in the filter housing and does that residual oil drain back into the engine or do you have to remove it with some sort of pump? The Haynes manual does not say if residual oil stays in the housing or whether you have to pump any residual oil out. Comments would be appreciated.

Remove top of filter housing before draining oil & the oil in the filter will drain into pan.

[P.E.Haiges]

If the oil filter is on the top of the engine behind the injection pump, the oil will drain into the crankcase and out the drain hole. You should also drain the oil from the oil cooler by loosening the bottom oil line connection to the oil cooler that is next to the radiator. It is about a 27mm nut.

I had not heard of loosening the oil cooler [connection] to get any oil that may be in there, out. Which brings me to this question: How much could possibly be in there, and wouldn't gravity take care of it? (ok, so its a two parter )

inquiring mind wants to know

It has about a quart of oil in the oil cooler and the hoses. You also need possibly a 23 mm thin open end wrench in addition to the 27 mm. Use the 23 mm wrench to hold the fragile connector while you are scissoring the nut with the 27 mm wrench. On a turbo 300D/SD, it is not a fun job to do due to limited space. If you are not careful, you can break the connector. I think the oil cooler for your 240D is only $200 ($280 for my 300SD).

I am in the process of buying a 240D. I had baught one new and sold it after 5 yrs. I loved the car but the power was not great. I am considering putting in a 5cyl. from a 300sd. Hads anyone attempted this feet. I will be getting a mechanic to to the job, as i no nothing about diesel engines.

I have never done this on mine, I don't think it's worth the risk of damaging the cooler to get the last few drops out. I change the oil hot, so hopefully the thermostat on the oil cooler is open and most of the oil drains to the pan. Does anyone else do it this way?

[sokoloff]

I wouldn't mess with the oil cooler lines either. If you change the oil from here on out at regular intervals, the little bit that's left won't hurt anything. Get the two little rubber O rings for the oil filter and replace them too. Use a good OE filter like a Mann, Hengst or Mahle/Knecht. Don't buy a cheap McParts filter. The OE filter ought to come with the big O ring for the filter canister and a new washer for the drain plug.

29 benzes, under no circumstances would i risk damage to my oil cooler unless the oil had been contaminated with something extremely bad. cant think of anything that bad.
