350 SL Valve Stem Oil Seals - 350SL Valve Stem Oil Seals

[Bill Adshead]

I'm told that it's possible to change the valve stem oil seals on a 350SL (type W107) without removing the heads by using a special MB tool. Can anybody confirm this or know somebody who can do it?

Replacing of the valve stem seals with the cylinder heads in situ is a standard repair & takes approximately  6.0hrs.

Would this also be the case for an 89 W124 300TE? The car whiffs a bit of burnt oil when you reverse it, though it is not using enough oil to worry me, or smoking a huge amount when driving. It has 140K on it.

Hullo Racingsnake?!?
With regards to your 300e, the valve stem seals can be replaced in situ. The job takes aproximately 3.0hrs.
Your vehicle is on the change. You should get away with just valve stem seals. On some of the older vehicles valve guide wear can also be a problem. If you vehicle is a facelift version. Then the vehicle should be fitted with the modified valve guides, which last a lot longer. If you main journey's are around town. Then you will not get a lot of oil usage. If you then use the motor way at greater speed. This may be when you notice higher than normal oil usage. You may see it when you decelarate & then acelerate at speed.
