You can tell if it is the exhaust by placing a hand over the
exhaust pipe end. It should change the tone or stop the noise.
 You can remove the valve cover and "spike the valves"
 (hit them with a rubber hammer) as it may just be
 a bit of crude that will bust loose.
 Also run the engine and recheck when warm.
 If it comes back, it may be worth a check
 with a boroscope before declaring alls well.

Mike Busch ? has written many articles in the various
 aviation press about clyinders, condition inspection etc.

40/80 is a small leak. I have flown engines that
 worked great, gone in for annual and had compressions
 or 0/80

 A TSIO may be an issue, on my Cessna a clyinder
 change is a couple of hours and $300 to rebuilt the
 same jug with all new valves etc.
