After fitting a wavetrac diff centre to my 2013 c63 i found that oil was
coming out of the breather after short run 2-3 km, i thought it may be the oil i had used so i refilled it with gen merc oil, i have check the breather and all is clear, i have now attached a long hose to the breather to raise it as high as possible, i still get some oil coming but only very slight, i have contacted wavetrac via arsha, and they have no idea what is causing it. i believe that the different shape of the centre is spraying oil at the breather port, has anybody elsle had this problem??? seams like i may have to install a shield inside the diff house to try and stop the problem,

take it back to the installer

I havernt had any issues like this and ive had it in for 10000kms

Maybe too much oil.

ClivePratt

I was the installer mr747.
oil is at the correct level, even tried under filling, same result, Merc63

Honestly I have not heard any problems

A few Aussies have these installed and no problems

Jasonoff

No problems with mine.

ClivePratt

The problem was the c clips that hold the diff bearings in were not aligned with the oil breather ports, the gaps in the c clips must be at the top. when installing a wave trac centre you also have to grind a little from the diff housing, they do not fit straight in.
all good now with no leaks.

Good to hear you got it figured out. To bad someone didn't know before hand.

Jasonoff

Yes it does. You just have to slip it in with without 2 ring gear bolts (beside each other) and install them after it's mounted by clamping the pinion.

ClivePratt

in my case it did not go straight in, even with two bolts removed, I also saw this posted by another installer, I guess not all casting are exactly the same,
no great drama either way

ClivePratt

there is more info on this forum regarding the need to modify the housing. https://mbworld.org/forums/c63-amg-w...d-special.html

You have to fiddle with it to make it fit. There was nearly 1/4" of clearance with the 2 bolts removed. I doubt the pumpkin casting would have that much variance unless they changed it in 2012.

That post is likely when all ring gear bolts are installed.

Damn I bet my issue is the same. Slight leak after LSD install. We didn't think we pinched the seals putting the axles in. Does anyone have any pics of this c-clip area? A local diff builder swapped my centres over so I haven't seen what's under the seals.

Is this breather port only on the same side as the breather?

I had a decent leak after having my Wavetrac fitted. The shop who did it said this is common as oil leaks out of the breather when you install a new diff. I got it all cleaned up and it hasn’t leaked since.

bradsm87

Mine has been 6 weeks and cleaned several times. It's worse than ever.

NAPARM

That doesn’t sound good. Fingers crossed you get it sorted mate.

bradsm87

Yep I really hope so. It's mostly been sitting on the front lawn for a month now. I really have absolutely no motivation to pull the diff back out again. It's certainly been a cause for a lot of stress in the household! My wife has had to daily drive the big 3 tonne petrol Patrol which puts the C63's fuel consumption to shame .

Since I repositioned the C CLIPS, 6 years ago now, I have had no oil leak problem, wish I knew about it before I fitted it the first time

ecohen2

I had the exact same problem a couple of years ago and posted it here: https://mbworld.org/forums/c63-amg-w...ed-advice.html

The problem was solved by repositioning the C CLIPS as @ClivePratt indicated...
