valve covers would be a good guess. I would also eyeball your intake manifold flame heater, it is prone to O-ring failure. I would verify that it's either plugged off (totally acceptable if you live in Northern Florida) or at least not leaking. If you start getting fuel puking out onto the top of your turbo, that is your flame heater o-rings...failing. Open the radiator cap, verify that you've got good, bright green coolant in there. Look in the access hatch under the driver's feet, check your brake fluid reservoir for proper (DOT 5 silicone brake fluid) level, and look for any funny business. Check the boots on the inside/under of your steering wheels, if the axle boots started to leak grease then RTV could likely have been used to patch it.
If you want to get a gold sticker by your name, crawl underneath and check the whole drivetrain. Oil pan--check for orange ATV in place of the oil pan gasket. Check the plug for abnormalities, including the plug being cross-threaded. Check your 3 differential plugs, for sealant (it should not be there). Check differential drain plugs. Based on your troubles, pay close attention around your transmission. Check the tranny drain plug, bell housing plugs, and the top of your transmission for another orange ATV job.
Good luck!
