W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

1982 300SD engine mounts question

I see the engine mounts from under the hood. I also noticed what looks like a mini-shock absorber. Is that part of the engine mount? Is it important? How can you tell if it is working? The engine vibrates while in idle but it has no effect on that mini-strut. The rubber mounts are soaked in engine oil but they are not torn. I'm not sure how old they are since I just got the car 1 month or two ago. Mercedes Source has a neat engine mount kit that I can buy but I was wondering if aside form the two rubber engine mounts and the transmission mount, if the mini-strut should be replaced?

1984 300SD ATF level drops when cooled ??

According to the manual, the ATF level should be 5 mm below the low mark on dipstick when at air temperature. I imaging this is because hydraulic fluids expand when heated and contract when cooled. I have the opposite: my level is at the full mark at operating temp, then rises about 2 inches over full mark after it sits overnight. It's as if the torque converter is draining into the pan overnight. The transmission is fine and doesn't leak.

Anyone have any thoughts on this? Thanx.

What model Mercedes is best for DIY?

Kent and all,

My youngest son has seen the light! After his 4YO Kia Rio broke a timing belt in Nowhere, Tx. he finally figured out the old-stogey Mercedes Diesel that his dad has driven for 305,000+ miles is the way to go.

He's got mechanical skills but no garage (other than Dad's)and he's on active Duty with the AF Reserve, right now at McCord AFB but soon in Alpena, MI and then on to Charleston for several months-Germany after that.

1959 6 cylinder Sedan Manual Transmission Interchange ??

Hello, I purchased a '59 220S that had the wrong engine and trans in it (mid-70's model). I found an engine with Type Plate M180.III 180.924Z and rebuilt it. I believe the transmission that I used was out of a 190SL, I don't have the number with me. The engine very quickly revs to high RPMs and seems as though the gearing is incorrect. For example, the car seems most comfortable if I am in third gear by 25 mph. I was told that all Ponton transmissions are essentially interchangeable with minor gearing differences, but now I am wondering if I have a problem with this marriage.

'84 300TD engine shudders while in park ??

Ok. I'm having some trouble determining what is going on after I've driven the car for a while then place it in park.

I get 1-2 seconds of shudder, followed by the same of smooth idle. If the same thing happened while stopped at a light, I might think it was idle speed/fuel delivery related (and it may still be). And occasionally after a spirited run, the engine will shake pretty good when I come to a stop, but smooth out pretty quickly.

But when I put the car in park it's a very quick shudder without much rocking like I get when I just stop in drive.

Any thoughts?

91 350SDL -- HELP - dropped something into engine

This is a new car to me and I was replacing the glow plugs. To make it easier I removed the Intake Manifold on that engine since some of them did not have the 'proper' nuts on the bad glow plugs.

My mistake was to not cover the intake holes and I think something fell into....ALL THE WAY into the cylinder (past the valve). I have all the nuts and bolts that I was using, so I can't figure out what fell in. After I put it together I heard a metallic bang, bang, bang when I started the engine so I shut it down right a way.

I am trying to find new rear axles for my 1983 300d. I know that they are refered to as can style, but all of the places I have looked call them either annular or homokinetic. Does anyone know what the technical name for the can style rear axles are? Thanks for the help!!!!

Coolant Resevoir W123 1982 Turbo

Hi Kent,

I just installed the thermostat on my '82 W123 Turbo and the installation went smooth and easy (except for breaking off the radiator drain plug - got a new one from the dealer). Now I'm at the point of refilling the resevoir with coolant (50/50 mixture with water) and I understand that the capacity is 13.2 quarts. So far I've only put about 4 quarts of coolant and the entire coolant resevoir looks full. Ugh. What have I done wrong, and what do I do next?

Thanks much,

Brook
