Welcome to the forum. Nice that you have some experience with Bobcats. If you make a post about the problems, you should have some new friends answering to help you.
I'm working on a Bobcat B300 with a Kubota V2203 engine. I'm looking for the oil dipstick tube seal. The seal installs into the oil pan and the dipstick tube goes into it. It keeps oil from splashing up out of the oil pan.
