Help! Recently purchased a 2022 318g skidder from an auction with 2500 hours on it. It's leaking oil from both breather cap/plugs right behind the control joy sticks. Looks like it would be a relief for the front axles as it's right above them. The tank is not over full so I'm not sure why it's flowing from them. It does it when it's parked not running. Any help is greatly appreciated as I can't seem to find much about it.

Ok, I know nothing about this machine but I have a guess.

Have you checked the oil level in the chain case?
Normally the hydraulic oil level has nothing to do with the chain case oil level. If the chain case is overfilled then that could be the problem.

If the chain case oil is over full, then there could be a chance that a drive motor seal is shot and filling the chain case with hydraulic oil.

Of course I could be way off base since I mainly work on Bobcat machines.
 
Ok, thanks. I'll look into it. Freaking me out since it's on both sides so maybe both drive motor seals are bad?
 
Oil looks really clean. With machine sold at auction did they service it just to sell it? If so, possible it was overfilled. Try looking on manufacturers or Messicks website for a manual or parts list. That might show you what is connected to what, a parts description and number to Google and search for more info. Good luck.
