Just had 2 year service at OPC for my C4S, they reported a slight oil leak from the cam cover. Before the service there was no oil leaking from the car, since having it back there are some very small drops appearing on the garage floor. Has any one else had this problem? Is it a major problem? My car has only done 17000 miles from new.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I think what they do is remove the offending cam cover bolt and dod a bit of sealant on the bolt and reinsert. The bolts on my BoxS were actually very loose so i removed the rear wheels and nipped them uplightly, The oil may be thinner/different grade than the older stuff removed and thus finding its way out, as also happened to mine. Mine was serviced today and i asked them to fix the tiniest drip from 1 cam cover bolt, done, with a bit of sealant on the bolt head Could be DIY if you have a few tools an a tiny bit of ability and an hour spare
Common on early 911s, as they distort.
