I went this long weekend to the beach with some friends and my 83 W126 SEL and it got really windy and the parking was right in front of the beach and gusts of wind kept coming and when I got home there was sand in door jambs and on top of the engine and air filter.

I cleaned the engine out and filter with a air compressor and the doors the car is clean but I am worried about the engine (internally) if it sucked up anything?

Its running perfect and added some injector cleaner should I worry?
