Engine Oil in Bilge
 

Twin 1999 merc 454 Mag MPIs w/Bravo 1 drives.

Problem: Engines run fine, but starting yesterday I found engine oil in bilge mostly under the starboard engine. Was pretty rough yesterday, so whatever oil leaked out was sloshed onto belt and sprayed all over the place. Can't see the leak after a cursory look.

It was recommended that I clean the engine and bilge first. Then run the engine to find the leak. What areas should I concentrate my time. I've heard the remote oil adapter seal on engine and the oil cooler.

Other feedback is greatly appreciated.
