I have oil slowly leaking out near the flywheel

Hi, been a long time since ive been on here. But ive been pushing my mower really hard lately, i have no govener on it so i do feather it higher then usual at time but not alot. I was talking on the phone in my garage and had the Urg to check the oil level. lets say ------------- thats how much SHOULD be on the dipstick (i triple checked too!) only --- that much was on my dipstick. But i had recently put new oil in it. and it was full when i did that. How can my mower burn that much oil in a matter of a month and a half at most. Well (my phone wont connect to the computer so i dont have pics) i noticed a liquid or oil substance was slowly coming out of the bolt holes in my flywheel and when i turned it over it would splatter. Did i crack my engine??? (if so idk if i can fix it. im 15 and its really hard to get a job now days :/)

seal under flywheel went out... if block/case is cracked its junk

how easy is that to replace? and thanks

$2 part 1hr labor. you are gonna need a flywheel puller. easy job with the right tools. I have seen guys trash a good motor trying to get the flywheel off with a pry bar and a hammer back when they had the points and condenser under the flywheels
