OX66 200 HP oil leak

Just had the HP fuel pump replaced and VST filter cleaned. Now have an oil leak into the motorwell when the engine is tilted all the way up. Any suggestions? Thanks in advance.

There is a small vent hose going from oil tank to air silencer cover and is routed behind VST, look to see if disconnected from air silencer.

That was it! Thanks for the help.
