What can be wrong with my truck? The oil stick measured oil level as too high but it is not.?

Question

was out today and check engine went off--blinking big time.  Got home and later (once it cooled off) checked the oil stick and it was way to the top of it--oil measured too high but it is not. I have always taken care of my truck so there is no way I would overfill it with motor oil.  What could have gone wrong or what is wrong with it?

Check the oil filer cap if there is white sludge you have coolant in the oil via the head ,head gasket if not have the oil sample but my best diagnosis is fuel My guess your truck is a diesel probably cracked head or injector "o"rings

The blinking engine light signals mutiple misfires and if cylinders aren't firing the gas that is unburnt drops passed the pistons and into the crankcase.
Check for gasoline smell on your dipstick, and figure out why it's misfiring.

Reckon maybe something else (such as water or fuel) got in there raising the level?

Check and see if you are getting air bubbles in your antifreeze holder for the radiator (with engine running). Cracked head casket will put antifreeze into your oil (crankcase). You could have gas (diesel) in your crankcase.
