Question Losing oil on drivers side of engine, unknown cause [Photos Inside]

So my engine is up there in miles 123,857 and recently have been losing oil. About 1.5qts in 700 miles, no good. My first thought was the pistons, but wanted to rule out a turbo seal and removed the TMIC and it wasn't that. No blue/white smoke and I hit boost fine. There is a hint of burning oil. I am limping the car when I need to drive it. I am going to IAG on Monday for a compression test. I did a leak down test and everything is okay. Yesterday, I hit the engine with purple power to degrease it to see the fresh oil today and I noticed a lot of oil/water running from beneath the car.

So today after putting the TMIC back on I went under the car and saw a lot of oil running down the drivers side of engine near the rear timing belt cover. It starts around the oil tube, runs down the block, past the coil packs and puddles in the tray. I am maybe thinking a the cam gear gasket, but what do you guys think from referencing these photos?

Seems to be right on par with this: http://forums.nasioc.com/forums/show...5&pagenumber=2

Puddled oil on bottom tray


Bottom of drivers side front timing belt cover


Laying on ground on drivers side looking up, oil collecting on block




I see one thread, I wasn't sure it was backing itself out or not

Looks like cam seal or valve cover. Kinda hard to tell in the pic, plus it hurts my neck looking at it.

Yep. When I saw the timing cover I was going to say cam seal, but then the later pictures make it look like a valve cover. Is there oil on the side of the valve cover? the plug tube seals tend to go bad also, but I cant see them in the pics.

only real way is to get in there and pull all the covers off and start removing some things to get an accurate answer

I will take a look tomorrow and report back, I am glad it is external oil leak rather than internal. I know cam seals at $5 from Subaru, I have to look to see how much a valve cover is.

I do not recall off hand, I want to say a little towards the bottom, but nothing like the outside.

Wouldn't hurt to check the top of the head towards the front. There is an oil line and a couple banjo bolts as well as an oil control solenoid for the intake camshaft. Those could be a source for leakage as well.

I checked the car, a little inside, mostly at the bottom of the timing belt cover. Elbert, I will also check that as well. The car goes in the shop monday to be on a lift to have a look. I decided to do a compression test/leak down test with a friend and will post those results as well.
