I had my 850, with 20 valve motor, up at the top of the property for two months while my wife wasn't driving (used her car). Now that I've started it again, I'm getting a ticking noise. If it were an overhead valve motor with mechanical lifters, it would be a loose valve rocker arm. But my understanding is these use either shims or hydraulic lifters, and it wasn't make that noise before storage; so not sure what it could be. It's coming from the area of the front (relative to the motor's placement in the car) camshaft.
Never mind....after five minutes, the noise went away, so I assume it was that the oil needed to work its way into all the nooks and crannies.
