Hey guys, I recently took out my ej25 block out of my na 2008 outback. It has had one head-gasket replaced already. i took it out because it was leaking oil out of the passenger rear cam seal. I was wondering if there are any other things that you guys would recommend I do while the engine is out of the car. It does have 160,000 on the clock.

Before you took it out, was the compression good? Burning oil? You could pull bearing caps to see if the bearings and journals are okay.
I did have it compression tested when I bought it only 300 miles ago and that was good. I don't think its burning a lot of oil just leaking.

It should be good for around 300,000 miles. Put it back in and drive the vehicle.

Make sure you keep up to date with maintenance items like timing belt kits at the relevant times.

The most important thing to do from now on is to do your engine oil changes regularly. The engine may use some oil but this is “normal” so check it every 2000 miles or so and top up as required.

Yep what he said, replace the leaking seals and put it back in. Replace any hoses that would be hard to get too later on.

Us with XT's and Legacy GT's would buy a new OEM ej257 short block, have our heads rebuilt install ARP head studs and have a great DD. My EJ257 has over 134,000 trouble free miles.

Is this engine subject that the leaking oil passage that bolts to the back of the block? If so, he may as well look at that as well while the engine is out.

If I were he, I'd replace all cam seals, the front and rear crank seals, and of course, to the timing belt and pulley change, and maybe the water pump.

If you want to go further, replace both head gaskets and have the valves lapped and their seals replaced.

Yep, just depends on how much he wants to spend.
OP think about what is easy to do while the engine is out...how long do you plan to keep the car...?

I’m only sixteen so I’m planning to keep it through college. I pulled the engine myself without any help.? I found the service manual online and it gives step by step instructions to do everything it’s awesome!

I’m grateful to have parents that would pay for any other things like new headgaskets, water pump, etc. I have to pay for any mods though like a short shifter.

Unless the engine was showing any serious oil consumption or bad noises beforehand I would leave it alone. Rebuilding an EJ25 is a bit more difficult than normal engines and best left alone if it doesn't need it.

here is where it is leaking out of. It just started leaking a LOT suddenly on my way home from school onto the headers and this caused a bunch of smoke. I stopped right when it started leaking

I’ll just take off the head to fix the cam seal then I guess

I replaced the front cam seals on my 08 2.5i when I replaced the timing belt 90k miles ago. I am going to replace it again soon and will replace the cam seals at that time. It only takes about 5 minutes with this tool. $13 at Amazon or most local auto parts stores.

Do you have the name of this tool?

That is a very unusual place for an oil leak. That “seal” is basically a plug to plug the hole.

Looking at the photo the head is much cleaner than the engine block and I suspect the head gasket may have been replaced. If it was replaced, maybe someone also replaced that seal BUT did not apply any sealant to prevent this type of leak.

You may just need to remove the valve cover and loosen the camshaft bolts so you can pop that bung out, clean everything up and then reinstall the bung with some sealant.
