This Post will apply to those M119 E420, W210 Owners:


Wow.. when I rains? It POURS!!

It has been "Leaking Oil on the Garage Floor, Central" at my house. Between the Leaking M112 (W210) and the M113 (W463) Valve/Breather Covers, and now the M119 (W140)? This is becoming my new Full-Time job... :^(

Anyhoooo, apparently this is a very Common Oil Leaking location on these Engines.

This is a REALLY Easy DIY solution.

Please note: The Specified Sealant 001 989 89 20 10, apparently is the EXACT same thing as Loctite 574. The price difference between the Two? Negligible.

Be sure to let the Sealant Cure completely BEFORE starting the Motor. It looks from the Curing Charts that 24 hours (at a 22C shop temp) is a good interval.

Greets to Kuwait!

Well, the material you are showing is not the "Specified" Sealant.

The material you are showing is designed for sealing Timing Cover Cases... Breather Covers, etc. You can see the same sealant in this post: http://www.benzworld.org/forums/w210-e-class/2281666-photo-diy-m112-breather-cover-re.html
It is BLACK, not Orange.

If it helps, I have heard the Rumor that Loctite 574 is the SAME material as the Orange
001 989 98 20 10. I think the price of the two are Equal, though.

G-AMG,

Your write-up on this was great as usual. I am preparing to do this on an M119 and I went by my MB mechanic friend to get some of the Loctite 574 sealant yesterday.

He warned me that the leakage is often at the solenoid coil connector rather than the mating interface to the cyl head. I went out to clean the area again in prep for disassy and it did look like at least some of the leakage may be coming out of the interface of elec conn & the cylindrical housing that holds the coil & mates to the block.

I wondered what your findings on leakage/seepage has been after you did the re-seal on these cam solenoids, i.e. did the re-seal largely solve the issue or do you still see some seepage?

Part of the problem with this issue is the seepage is so miniscule that it doesn't even really make thing wet, it just gives dust something to stick to and slowly build up a coating of black dust.

Can you provide an update on your findings?

Yes, in my case, NO more leak.

But, YES! I understand the Electrical Connector is the Culprit in many cases..

'Your mileage may vary'... You'll have to check for yourself, 'Where' your leak is most likely arising from..

I don't think the Adjuster is 'that' expensive.. (Under $100 clams if I'm not mistaken), if all else fails.

I used some 3M 2216 epoxy to whet/seal the interface of the elec conn/insulator and the steel housing just for insurance.

The 2216 never gets hard/brittle and sticks to almost anything.

Thanks for your write-up.

This job is dead easy so there's no reason not to do it.

A little 'pat on the head' and thanks for the 140k miles of devoted service.
