I developed a tick it is very audible inside the car, but only when there is a load on the engine. Its really loud I originally thought it was coming from inside. I can hear the ticking when the clutch is in and in neutral when reving but not nearly as loud as with load. I checked for exhaust leaks but, found none. Has anybody had any experience with this? I haven't had time to pull the valve covers yet just wondering what to expect.
