Noise when starting the engine

Sounds to me like an injector dripping fuel onto a piston overnight.
In the "old days" with big engines like EMD's it was a known issue, so you opened up a bleeder valve on all cylinders, pulled a dead rack and rolled her over a few turns to "blow it down" meaning to clear the cylinders of any fuel or oil leaked in while it was shut down. The radial airplane engines were about the same, what, nine prop blades ticking by before the fuel came in, to clear engine oil out of the lower cylinders?
