Replacing Spark Plugs - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I have a 2001 (50,000+ miles) with a small oil leak. It's not coming from the oil drain plug and I think it might be coming from the spark plug. I know the spark plugs have o-rings that can cause the leak and my question is: what tools are necessary to replace the spark plugs and how difficult is the job? The car is scheduled to go to the dealer is coming Monday and I know the bill isn't going to be small. If it is something I can do to save money than I'll give it a try. I don't have the skills and knowledge of a mechanic but I do atleast change the car's oil and other minor fixes.

Is there a quick way to be sure that the leak is coming from the o-rings? What other places could the leak be coming from (before I decide to cancel the appointment)? Should I be smelling a burning oil smell in the beginning if it's the spark plugs leak? There is no smoke when I have the car's engine running or idling.
Thanks...

The plugs are easy to replace. The O-rings look to be easy too and a cheap replacement. If you go to the Boxster maintenance section on my website there are instructions and required tools for plug replacement. The most important thing is to get the correct spark plugs with the proper heat rating of 7. I have the part number listed on the site, just don't settle for the plugs sold at the local auto store. The site linked above have '97-'99 for the plug, but they are actually for '97-'04.

The O-ring instructions say you just need some expanding pliers (the ones that open when you squeeze the handle rather than close and grab) to put in the plug tube and pull it out.

Whatever you decide to do, you should get the Bentley manual so you have some kind of reference while you work on things.
