I have oil dripping from the airfilter on the fuel injection pump on my 230SL and it causing nasty marks on my parkway so I need to stop this some way.
I have searched/read trough several Injection pump treads here and can see that the leakage comes from a bad sealing in the injection pump that should probit engine oil to go in to the injection pump oil resouvar and the only way to solve this is to have the pump serviced, a costly job as I’ve understood.
Now to my question, my engine runs well and the car drives well, what can happen if I don’t do the service on the injection pump apart from getting oil stain on the ground?
I made a intermediate solution to get rid of the dripping oil, I collect it to a container outside the pump that has a capacity of about 0,4l that I can drain manually from time to time, it ought to last for at least 1000km.

Your choice: Pay for the repair or continue to use a drip pan for free. Just be sure that the pump continues to be lubricated. As an aside, it appears that anything approaching 0,4 liters/1000km through the pump is wildly excessive and bespeaks of a major problem that should be addressed.

In my opinion the pump is completely dead and there should be no discussion what to do! The pump should be repaired. All the best, Martin

Of cause I will do the rebuild but I would like to wait until I park the car for the winter.
I have to correct myself, the leakage is from the oil resouvar filling cap, see picture.
The dripping oil shows where the red ring is.
The dripping oil is very black so I think it could be positive that the old oil is pressed out buy the new oil as I recently did the engine oil change and the dip stick shows the clear oil.
And a picture of the dripping aid solution :)

By the time anything starts to overflow out of the oil filler cap, the IP crankcase would be more than half full of gasoline. Not only will this affect the governors inside the back of the pump, it will also cause all of those moving parts to wear, especially the stylus that follows the three dimensional cam. All of these parts are supposed to run in engine oil and gasoline has very little lubricating value.
Best to get it fixed now before you do any damage which will only cost more to fix. This is not one of those limp home down the side of the road situations.

Thanks all for your input.
Today I pumped 0,9l out of the IP which should only contain a maximum of 0.25l so it is well lubricated and yes it smells of petrol!
I am fully aware of the petrol's poor lubrication effect, so now that I have pumped out old oil/fuel and filled it with new oil, the pump should not be damaged more than if I did nothing.
I have found a company that can service the pump locally where I live at an acceptable price, so the service will be done during coming winter.
