Default head gasket or what?

99 legacy w/ 162xxx. there's oil throughout the valve covers including leaking through the bolts on the valve covers, but theres also a good deal of oil coming through the timing belt cover as well. its hard to see where else the oil may be coming from without a lift so i want some more insight.
If it were a head gasket as well which after doing some research im thinking not...there should be coolant leaking and steam coming out of the tailpipe if its an internal gasket failure and also coolant on the spark plugs which ill have to see about tomorrow.
but if it's nopt a head gasket what else would it be to cause oil leaking through the majority of the timing chain cover if its not the valve covers?
help greatly appreciated asap

Camshaft seals. How long do have this car? Have you recently switched to full synthetic oil?
On Subarus the head gasket issue does usually manifest in over heating due to air pockets in the coolant system. In my experience it is rather rare that coolant leaks out directly at the gasket, nor do you see white smoke out the tailpipe.

Sounds like it's time for a timing belt change including all seals and valve cover gaskets. Replace the water pump as well while you're at it. Before you start have a trusted shop check for CO2 in the coolant to determine if the head gaskets are bad. If they are any questionable I would do everything at the same time, saves you doing the timing belt again prematurely.

Hope that helps.

Ya that's what I'm doing. Do everything at once and then some to prevent and to get ahead in maintenance. The valve covers were leaking. I replaced them yesterday. Brakes need ti be bled some more though. Spark plugs were changed since they were covered in oil. Spark gaskets changed so hopefully those are good now. I removed the timing belt cover just to see if anything was too bad because the bottom of the cover did have oil dripping but nothing seemed toobad yesterday so I figured it was residual from the valve covers. There's oil on the left side of the cover along with on the coolant hose eight next to it. Could be coolant too can't tell really. The rear main seems to be leaking too because on the rear just to the left of the right valve cover its got a good amount of oil too
This is my fiancée car we just got back in mid November and nothing was leaking at the time. Its something that's just been coming up. And the timing belt was also just changed he said...although you can't tell because the sticker has no date it mileage printed. I'm going to do her cam seal along with the timing belt, water pump, and idler pulleys. Its just weirs that its dripping withoil on the left of the timing belt cover but when I took it off yesterday it wasn't soaked.
