Welp, here comes the first big bill
After 15 months of fun with the double-nickel, she's developed a bit of an oil spotting problem. Definitely coming from above the pan. Seems more on the passenger side but I assume that's just the easiest path for it to follow. I saw my garage floor and knew it was probably time for some surgery.
So I did my due diligence and searched, but it seems no one has ever confirmed the parts needed for the job. Can we get a guru to confirm these? I'd like to get the parts ahead of time so I can just roll into an Indy and tell them to get cracking. Here is what I've found so far.

You will need new bolts for flywheel as they are stretch bolts
the torque converter bolts part number is A 124 990 22 01.... i think you need eight of them

(rear main seal)part# 112 997 0246
rear main seal retainer # 112 011 0208

You also need:

End cover

Trans fluid as you have to drop the trans and drain

might as well do oil change when your there as when you remove the end cover you will lose some oil

when you have the trans out might as well flush it, change the trans filter, and do the electrical plug as well.

And lastly, a vendor chimed in that did these jobs and stated this was their package:

MBZ Rear Main Seal Replacement:
R&I Transmission
R&R Rear Crankshaft Cover
R&R Rear Main Seal
R&R Flywheel Bolts x8
R&R Transmission Line Seal x4
R&R Pilot Bushing
1 Qt of Mobil 1 0w40
1 Qt of Transmission Fluid
Mercedes Benz Sealant

Just remember cure time is important. At least 4 hours to cure or else the problem might come back again

they will make you chance the rear main plate since the seal has been updated

if headers were ever on your list it may be a good time if they have to remove some of it to drop the trans... when did they redesign the rear seal and plate ?

jmb614

Does the new design come as a unit, i.e., seal installed into plate and sold as a unit? When I replaced mine a couple years ago that is how it came.

whats the correct part number for the updated seal and end cover?

ALEN35

I hope my seal is not leaking again because I know they didn't let it cure for 4 hours. They called me soon as they were done with it. I will have to check it out!

how much does this job cost at the dealership? what's the range? Can anyone that had it done at a dealership chime in?

I was quoted 1100 CDN at an indie.

Paid the guy I used to maintain my E55k $250 to replace my rear main.

A.M.

250? Was quoted a 7 plus hour job. My second opinion came in at 900. You got one hell of a deal...unless we're not talking about the same thing.

justinwrock

Yep, rear main.

Ask my of the local guys, we have a pretty awesome guy up here that does our work. Toadster, frome55tom5, ryouki(sp?), etc.

A.M.

Lucky. Unfortunately, I live in Volkswagen Audi land. Damn snow.

I checked today with the parts guy at dealer for info on the end plate. Searching by my cars WIN there was no indication in EPC that the end cover should be replaced also. There were 2 numbers for the rear main seal, both were for the same part. There really was no info that end cover should be sold with the seal

So we basicly by accident checked the crankshaft, and it has been upgraded in motors after WIN numbers reaching "something", probably somewhere in 04/05 and there was clearly info stating that with the new crank there should also be sold new bearings and both main seals.

So has anyone got better info on this, and know for sure that the end cover upgrade effects all engines across 03 till 06, and if it does is it because the seal itself has a different outside diameter?

Also what is this?

" rear main seal retainer # 112 011 0208" ?

Its the new End Plate

found a good deal on ebay for the plate and seal if anyone is looking to do this job (OEM Benz)
