993 persistant oil leak,solution needed
A question posted to anyone whose experienced this same leak.
I got a 993 engine in my 914/6. The oil temp/pressure console has leaked since the day I first installed the engine and fired it up. Never a bad leak, but a leak that would wet the top of the engine after an hour drive. My first attempt at repairs was to obviously replace the o-ring under it. No cure, so then I replaced it again, and this time I made a gasket to go with it. Then I thought the oil pressure might be to high, and removed and checked all the pressure plugs and springs only to find nothing unusual there. The console continued to lightly leak, but leak none the less. Last summer I pulled the engine to do a full top to bottom overhaul, and after I reinstalled the engine and fired it up the engine has not leaked at all, and has stayed completely dry for the first 5-600 hundred miles of driving. Now I'm at about 7-800 miles on the engine, and lo and behold, the sorry oil has started leaking again from under the oil temp/pressure console. The car has averaged no higher than 205 degrees after a good run, and the oil pressure on the gauge is saying about 90psi riding down the road at 60 mph @ 3000 rpm. I'm not sure I can truly believe the gauge because it is not a 993 OP gauge married to the 993 dual sending unit. Who has fixed this similar problem, and what did it take to make this oil leak go away????  Thanks Ron

Are you 100% sure it's coming from the o-ring?
Other possibilities are: Oil pressure sender Temp sender the screw-in galley plug next to the housing (the one with the internal hex drive)

Is it a Varioram engine? Could the moisture be coming from the bottom of the intake manifold? I've seen those make quite a mess on top of the motors.

i have a 95 993 motor and had oil leak in the same area. mine was coming from the oil pressure sender. put new aluminum crash washer and fixed. i was prepared to do a copper crash washer but was not necessary.
