This instructable is how to on changing the oil pan and or the oil pan gasket. there are a few reasons you why you would have to change one or both of these things. One being, not leaving oily patches where ever you might stop. Another may be the environment or spending less on oil. this should also be done in conjunction with an oil change. And as it happens, I have done an instructable for that too. Also do it when the engine is cold. there is little point in burning your self.
The reason you may have a leaky oil pan is simple. your car is 32 years old and it has a few dings in the pan. Which warps is, so there is no longer a tight seal. Secondly, the gasket is 32 years old. But if your reading this you already know these things, and just need a few tips to get the job done.
One of the side effects is improved performance dont you know.I gained a noticeable amount of extratra "pep" or a "few more scolded cats under the hood" after replacing the pan....
Do not under estimate how dirty this job is or how long it will take. Start it in the morning just in case something goes horribly wrong. like you accidentally fold the gasket or something. Some sites on the web say it takes no more than one hour, but thats if your have done it before. It is a simple job, but as you will see, sometimes the car will through a monkey into the blender. If you know what I mean....
Step 1: Tools
5mm Hex socket,
6mm Hex socket,
Torch wrench (I got mine on the day from Kragens for $9.99, works good)
A 3/8 to 1/4 converter to go from the torch wrench to you Hex, (if you need one)
Jack stands or a pile of 4x12s ( I used 4x12 railway sleepers until my neighbour saw me and was so shocked that he lent me his stands).
Oil catcher thing -- 4 litres plus ,
Disposable gloves -- Not a requirement, but useful.
Old cardboard boxes (to lay on)
All Mercedes are in metric! Using imperial sockets or wrenches may work (sort of) but you'll just round the nuts off. And no one... NO ONE wants round nuts.
These will do and they are cheap. http://www.amazon.com/Neiko-7-Piece-8-Inch-Socket-Metric/dp/B000IQNMQU/ref=pd_bxgy_hi_img_c
