SL 500 oil water mixture / parts
 

Hi .
New to the forum
I own a 1995 SL 500
The oil mixed with the water , I suposse that an old O ring from the distribuition cover failed. Does anyone knows of specific failures regarding this matter?
I´m also looking the way to order parts straight from the plant . Has anyone tried with succes ?
Any recomendations to buy OEM parts in the us or europe with fast delivery time and low prices?

thanks
Fernando
