Greetings SLK owners,
After an eventful couple of weeks with our new SLK 350 we have finally had a success story
An oil leak was found.......not great news but looking at this marvellous forum soon revealed several suggestions. The cam expansion plugs looked a simple enough repair and the leak was from the larger of the plugs.
Surprise surprise the main dealer parts specialist needed some help in identifying the part but confirmed there was stock available.
Old plug prized off with screw driver - very little effort required. There was plenty of oil in the plug and it was easy to see how some of this would seep past the seam.
The existing cam plug has part number: A000 997 78 20
The new cam plug has part number: A000 998 56 90
Comparing the two I can see the new plug has a more pronounced o-ring. It could be that the existing plug o-ring has got compressed during its life.
Still, great news the leak was simple to fix. I thank the forum and its members in sharing several articles on this subject.
Following information from other articles I cleaned everything and installed the plug dry - in other words did not smear oil or grease on the new plug.
Overall, the easiest engine oil leak to fix!
Now onto the more serious issues of heated seat base and the random parking generator aka parktronic.
Enjoy a weekend of SLK driving.
