There are no signs other than debris and using a diagnostic tool like piwis or diametric to read the cam deviation angles. If you let the deviation get too far out of spec then you could get a check engine light (best case) or a bent valve (worst case). You would get a bent valve if the chains jump time.
Often these cars develop seeps in their cam covers. It is common to service the cam pads when you reseal the cam covers because you’ve already opened up the top end. The problem is few people want to do this repair with the engine in the car. You do get a better repair with an engine out service.
