Dipstick won't go back in

do stock type 340 pans have baffles? how far in are you able to get it? I have found on more than one occasion that the lead edge of the dipstick can catch on the edges of a baffle.

Steve, you thinking the dipstick is hitting the crank?
Remember, I wrote above that I am able to insert a plastic rod that is almost the same length as dipstick without any problem.
