"Is there anything else more sinister that could be causing this?"
Years ago I was motoring and heard a "crunch" and instantly smoke was puffing out of the oil fill. The engine ran fine but seemed to have lost some power. She got me back home, a trip of over 1000 miles and I did a compression test. One cylinder showed about 45 psi. The others 120+- psi. I planned to make more long trips so I decided to rebuild the A-4 and found that the rings in the low compression cylinder had snapped/broken. A rare occurrence.
