There's usually little to no leaking with a bad crank seal but they can suck in air through the seal causing a lean condition. Pulling the motor is not gonna show you much as far as a bad crank seal, you might could pull the clutch and look at the seal and see if there's any sign of slight seepage or what not coming out around the crank. That being said that particular sled is pretty easy to get the motor out. The motor will be bolted to either an aluminum plate or two straps that then bolt to the chassis with two bolts in front of and two in back of the engine. Remove those bolts, the belt, exhaust, carbs and the wiring connected to the mag side and it comes right out. The belt is the only connection between the engine and the rest of the drive train so no need to mess with any of that.
