Ranger 1000 oil leak

I already did what all the forums said about replacing the oil seals but there's still a leak. What else might be the reason for this?

Did you check the gaskets? If theres a leak, first things to check are the oil seals like you mentioned, gaskets and hoses. You can also check the oil pan for damages.

You can try to clean the mating surfaces thoroughly and check for any hairline cracks in the housing or cover? It is probably a warped surface or maybe the crankcase ventilation system causing pressure

I guess what you need to do is to double check the crankcase breather. Might be clogged and causing the pressure. Just like what @Wholee here mentioned. So look around the valve cover and cam chain tensioner as they can also seep.

Additionally, if you've replaced the oil seals and there's still a leak, it's a good idea to examine the shaft surface for any signs of wear or damage. A compromised sealing surface could cause the new seals to fail quickly.
