Not sure that you would want to do this as a scheduled maintenance item.

Having gone through this, I now know what to do if the oil pressure drops/changes suddenly! Didn't have a clue before but now it would signal removal of the valve cover(s) to immediately fix.

But the bad part is, that you may not get a tick-tick sound right after the oil pressure changes. Thinking back, the oil pressure changed, then about 2 - 3 weeks later, the ticking started.

If you don't wait, you would have to pull both valve covers in the worst case to find the 'culprit'. It only takes ONE open oil tube to drop the oil pressure but without the tick-tick, it's a crap shoot as to which side it's on.

Re 'SOUND': Mine was a nice clean tick, with a 'clean' note. Not a 'smashing' sound but a more clean tick! Anyone can hear it from the outside although it's almost impossilbe to hear in the car with the windows up. Hope that answers your question.
