oil change 1970 2.8

Make sure to wear gloves you're not fond of, the bigger the gauntlet the better as it prevents oil from cannonballing straight down to your armpit.

Well I tried to drain the oil with my mityvac thru the dipstick- but nothing doing there. I pulled the oil pan plug, then waited and pulled the filter housing off and got some out slowly that way. I bought some Castrol 20-50 and used that- the 10-40 will go in the Venture, and the Rotella will go in the 82 wagon, and the Mobil 1 will go in my wagon. The filter I pulled had a metal preforated surround around the paper element, the one put in was Bosch made in germany but was paper pleated top to bottom with metal ends. No rubber parts with the old element or included with the new one. Two copper crush rings and one non copper ring- the housing bolt had the non copper and I replaced that, as well as the oil pan copper crush washer. New o-ring as well. Boy did she like the oil change! Valve noise was significantly less. No leaks. Now I have to figure out which cars to sell- perhaps even all three and get the wife a much newer wagon.

I was able to let the oil from the housing out slow and get a grip so that my hand was higher and it did not go down my arm. I like being skinny sometimes. I did use my ripped jeans, my hospital surgery gown, eye protection and sissy gloves.

I found that running a tank of 110 octane leaded fuel through my 250 does wonders for the valves. And it's nice to be able to haul aproximately 11.45% more ass than with normal 93 unleaded. Haha. I've had nothing but good luck with the Castrol "High Mileage" oil 5-40 weight in my 250. It cleaned the hell out of the engine, and one of those magnets that clamps to the side of the filter isn't a bad idea either. You'd be amazed how much metal floats around unnoticed.

Hello,

As "J Mela" metinoned, you should always check to see if the upper rubber seal is in place in the oil filter housing on the block. This seal, seals the oil filter at the top. It is gone most of the time. When missing, oil will by-pass the filter!!
It is not included in the filter kit and it is often times missing on your engine. It is important that all you guys check for this on your engines. You can be using the best oil in the world, but your just wasting your money and ruining your engine if this seal is missing. It is located in the aluminum housing mounted on the engine block and is directly above the oil filter canister.

Even if your seal is still there it is probably brick hard or compressed from never being replaced. The new ones are soft and pliable. You do not have to replace it every filter change. It is two or three bucks from Mercedes. The W113 Pagoda SL Group has a lot of documentation with part numbers, pictures etc. on their web site.

Most single overhead cam Mercedes six and four cylinder engines used this style filter configuration from 1958 through 1973. Some of the four cylinder engines used it up into the mid 80s.

Are these the part #'s?

MB P/N 000 184 32 80 and 000 184 17 80

or this one?


A000 184 33 80

Also- my filter did not have the metal around he element- but the previous one did- should I be concerned? The new one was a Bosch from Germany.

Hello MTU,

Most of the good original quality oil filters for these cars do not have a metal outer skin.

It is not the outer construction, but the quality and grade of the filter paper which is most critical. Your Bosch filters should be fine. Other OEM good brands are Mann, Mahle, Kneckt, Hengst....

The upper housing seal whichis usually missing is #000 184 3380.

Two additional rubber seals are also in the bottom of your filter canister. They do not come in your filter kit. They do not have to be replaced every oil change, but should be replaced occassionally since the rubber hardens with age. These do not fall off and disappear like the top one. They are a bit harder bto change; #000 184 3280 and #000 184 1780.

The large rubber o ring in the top rim of the aluminum canister comes with the oil filter and is #181 997 0341.

Well now I'm gonna go get all three and pull the element and install those. Won't do much good for the engine changing the oil and filter without the these!
