Does anyone have a photograph of the correct oil pan for a 1969 280SL?
My oil pan is black sheet metal and is dented. Thank you!

Engineer,
My '68 280 oil pan looks like the one in the picture in this thread:
http://index.php?topic=7932
However, the size is different. My 280 oil pan gasket was too big for a 230 which I believe is the same as the 250 in this picture.
Sorry, my 280 oil pan is hidden above a skid plate...
I believe this one is a later (70/71) oil pan with ribbing and a small drain plug?

Peter take a look at Brian Peters Motoring Investments site. He often has pics of the undercarriage of all his cars. I am curious if a '69 pan is the same for an automatic as it is for a manual transmission?

Thank you for the answers. May I re-phrase my question: Attached you find two pictures of the oil pan on my car. Does it look like the original oil pan that came with this model?

Hello Peter,
These engines have two piece oil pans. The upper aluminnum pan and the lower steel pan.
The W113 cars actually had three versions lower steel oil pans and at least three versions of the upper aluminum oil pans.
The first version (lower) used on the 230SLs, 250SLs and various MB sedans, had an 18 bolt, smooth bottom, steel oil pan. It used a pan gasket #189 014 0022.
The second version (lower) used on the 280SL and various Mb sedans, had a 19 bolt, smooth bottom, steel oil pan. It used pan gasket #108 014 0080.
Both these early types used the "larger" drain plug (17mm hex, replaced by the 14mm allen style).
The third version (lower) #110 010 0313 was actually supplied in Febuary 1972 (after the end of W113 production). These are the correct replacements for the 280SL series and all M130 engines. They have some improved features and are considered an upgrade. This last version is a 19 bolt, "ribbed bottom" steel oil pan with a smaller 13mm hex drain plug. This version is deeper and increases oil capacity 0.5 liters. The ribs add strength and slight cooling capacity to the steel pan. The smaller drain plug has less of a tendancy to be knocked loose from road hazards.

The factory supplies a rubber adapter for oil pick-up for the oil pump to be used with the new "ribbed" pan. It extends the oil pump pick-up furhter into the new deep pan. This adapter along with the oil pump strainer #130 180 0655 should be replaced before installing the ribbed pan.

In addition, the latest version upper aluminum oil pan supplied by the factory is also an improved design. This aluminum upper oil pan produced after W113 production, has cast aluminum fins or channels cast inside the oil pan to help direct oil back into the lower pan. I suspect these ribs also improve engine oil cooling capacity also.
These improved parts are most likely what you would recieve to replace your originals from Mercedes? In addition these seem to be the standard parts used on the later M110 Mercedes six cylinder engines so there is a good supply of good used units out there.
Some facts; You cannot replace your 18 bolt steel oil pan with either 19 bolt oil pan unless you replace the upper aluminum oil pan also. You can replace your smooth 19 bolt oil pan with a steel ribbed version as long as you add the oil pump adapter. You can convert your earlier engine by changing the upper aluminum oil pan after which you can use the latter improved ribbed steel pan. be aware that the dip stick arrangement in these pans vary slightly also so you would need the correct dip stick also.
The latest versions of Factory Shop Manual cover some of this information Sec. 18-6/1
I will post photos in the next couple of days.

Hello,
Yes, Bob's second picture is of the last version ribbed steel oil pan with the small 13mm plug. These were not actualy supplied with the cars when new, but are the correct replacement parts from Mercedes. It increases oil capacity by 0.5 liter.

Thank you for all the answers. I counted the bolts and came up with 19. I had to use all the fingers on both hands and had to take my socks off to use my toes also. It's difficult to do because I was laying on my back. I'm so lucky that I didn't run out of digits. Don't ever make me count over 20 please! Thank you Joe!

I used the ribbed oil pan on my car. Since it has the 250 engine it fit without any problem. You have to use the ribbed pan with the oil pump that has the rubber cone on the bottom. This pump is different than the earlier oil pump and it has an oil pressure relief valve on the bottom. I believe the earlier version was made without one.
The aluminium portion of the pan has curved vanes in the bottom with slots milled where every connecting rod would have to pass. This must produce some sort of vortex or a windage tray to pull the oil down into the sub pan at a higher rate than the flat bottomed pan. Oil capacity is slightly higher as the pan is about 7mm deeper.

Just to add to all this fine info -- my MB replacement 230SL block has the ribbed 19 bolt 13mm hex plug type pan.

Hello James,
This is good infomation, just as I thought, Mercedes supplies the upgraded parts for even the older models.

The 1968 280sl that i am just completing has the 19 screw pan fitted(flat bottom) and it has the rubber extension fitted as per the pcture above.
The 1970 280sl that i have just aquired has the same 19 screw pan fitted(flat bottom) this does not have the rubber extension fitted,is it possible to obtain from MB the rubber extension,if so what is the part #.

Hello,
The new rubber pick up is to be used with the ribbed oil pan.There is an early and late version rubber pick up. The late one is only to be used with the deeper ribbed oil pan. This late version rubber pick-up is 48mm in diameter and is 34mm high compared to the early version which is 45mm diameter and 16.5 mm high.
When fitting the later version, the metal strainer and rubber pick-up are changed together part #130 180 0655
Refer to page 18-6/1 and 18-6/2 if you have a BBB.

Joe is right about this. Thse are things you find out the hard way and it's a testament to this site that you don't have to go hat route.
Fitting the late style pick up into an early style oil pan wll pretty much crush the rubber pick up and possibly damage the oil pump strainer.
