I wouldn't wait for symptoms. Chances are you won't see any until it's too late. If you drop the oil pan, you might find some bits of gasket in it if they are starting to fail, but that's not really a convenient check. The biggest issue is the stock oil pressure sensor does not illuminate the dash light until pressure is so low that you have likely already compromised the engine. Probably the best way to get a heads up on gallery gasket failure is to install an aftermarket oil pressure gauge so you can identify the oil pressure dropping long before the dash light comes on.
