93 Legacy wagon oil leak

[George]

235,000 it should probably leak, but a dealer/owner of a used small
Subaru lot said it had to be the oil pump. Prompto changes the oil and
the oil pan gasket has been checked. It seems pump related in that it
seems to leak down to a point on the stick, but I never get an oil light.

Is there a history of oil pump leaks and where can I find out where &
what to fix. It's wet with oil above the passenger side valve cover.

Thanks

well if its leaking above the RHS valve cover(I am guessing that this
is a LHD model) then it in no way is the oil pump leaking as the oil
pump is mounted on the front portion of the Crank behind your
cambelts,My guess is that the tappet cover gasket has gone hard and has
started to leak this is common on most vehicles after the milage gets
up there it is a simple job to replace but requires the removal of the
air intake and filter box to gain access...

I did a visual check on the tappet covers, but the engine is wet further
back on the block than that. After adding quart of oil, I started up the
car to warm the oil before checking the stick. While the engine was
running, I noticed a bit of oil slowly pulsing out the top of the oil
pressure sending unit right where the electrical lead attaches.

It's a tough spot to get to, but I managed to get a spanner on the nut
and it was essentially tight. I'll have to get a socket with a u-joint
to try tightening it any more.

Anyone have this problem before or know what might fix it?

TIA

Not on soobs, but I replaced that part twicw on a Colt Vista wagon.
And beware of after market, they sometimes have an easily clogged,
smaller opening. Get the soob part. check www.subarugenuineparts.com and
ask for/email jamie or you local dealer. I doubt it is loose - the
plastic whatever insert is cracked or bad.

I suppose there is a distant possibility your oil pressure release valve
is stuck and your oil pressure is too high. doubtful
