Hi guys, I have two 1994 E420s with the same leak.

(caution, 1600x1200 picts)

HERE is one. You can see the leak toward the right hand side of the picture.

Once I remove the cam adjusting magnet, it looks like THIS .


Whats do I need to buy, and how do I fix this?

Thanks a bunch.

Looks like mine three years ago.

MB sells a sealant for this. Like an idiot, I bought a tube from the dealer ($60)!

Oh yeah, clean the excess residue first before applying the new sealant...

ah. so there isnt some rubber o-ring or gasket or something I have to replace, just use some over the counter high-temp silicone right there in between the cam magnet and where it sits. I dont have to take off that large nut. Just clean it all up....dosent sound too bad.

cool thanks.

ther proper sealant is not silicone, i dont recommend silicone mainly because if it gets in the adjuster it can clog the oil passage preventing it from working, mercedes uses what they call a flange sealer, it is anerobic in nature similar to lock tight,i have some at work i will send you if you want it,but i will be off from work until the 17th of may, the mercedes part number for the sealant is 002-989-00-20, i would sugget you invest in a tube, ther amy be others here who need it, if it is that expensive you guys could pool your money.

is there any particular place to apply this flange sealent or just make a bead on the bottom of the cam magnet and press on?

apply a coat to the mounting surface on the front cover, applying it uniformly, after you bolt togeather torque to 10Nm, wipe excess from area,
