2003 boxster s oil leak after winter storage

[goodman]

Thanks for all the advices, I own it since 2009 and only put 9000km on it since. It was never leak a drop since my ownership. Next week I'll take it for a good inspection or repair. Will post the result.
BTW, the engine was replaced by the dealer in Aug-2006 at 32,000km...so the "new"engine has only 20,000km and I hope it has the new version of IMS bearing.
