leaking through ring
 

looking at buying my first 911. The car is an SC with 108K. I had a leakdown done on the car. All were 5's except #6 (closeset to the passenger seat) was an 11. Mechanic confirmed it was coming from the ring. Is this a car I should steer from or is this normal. Note: the car sits in heated storage in the winter and was just taken out.

Depends what you plan to use it for. Seems acceptable, if you are not planning on getting another 100k miles out of it and that you are not going to beat the heck out of it at the track. AND if the owner recognizes that there is an issue and offers some form of credit for it.

How will I know it is time to fix the problem?

excessive oil consumption would be a tell tale that the prob is getting worse, plug fouling up perhaps, others will no doubt chime in here though

I've found that a single leakdown test can be confusing. I'd run the car on the hy in 4th between 3.2-3.8k rpm for 20mi and do another test.
