you could take an air blower and blow air down the dipstick tube. I've honestly never heard of this problem before so I'm at a loss. The oil pan isn't hard to remove and will give you a definitive answer. I advise you to take the dipstick down with the pan because the dealer says they always get stuck and corrode into the pan, which mine did.
Could get the oil nice and hot and then change it, that should flush out anything in there.
