I know in that case oil will be "sucked" out of the hydraulic tappets and damage would/could be caused to the valve train. Would I hear clattering on engine start and would the noise continue? Or after initial clattering, would the tappets fill within a few minutes and the clattering disappear? The trouble is that someone else did the first start and he didn't report unusual noises. The engine has subsequently run for two hours including four flights. Should I now undertake investigations for damage and if so, what should I be doing to put this worry behind me? Rocker covers off and look at valve spring caps? Check magnetic plug? Prime the oil system again to purge air out of the tappets? Your advice would be very welcome, thanks.
