IF any "dirt" falls in, get it out as best you can, or it can damage your engine. If a little sludge from inside the engine dislodges, no biggie. Do not put any sealers on the gasket, as they could react with the material the gasket is made of and actually cause a leak. Staying with the synthetic won't hurt anything, but I have always felt synthetics are overkill for a non-modded daily driver and the rewards (if any) do not justify the extra cost.
