Recommend the following:

-DO NOT ATTEMPT TO START THE VEHICLE.
-Inspect timing belt as listed above.
-If belt has failed or jumped due to component failure order this kit: https://www.rockauto.com/en/moreinfo...305504&jsn=406

If valve contact has occurred:
-2.2 engine swap (see the many threads on this here). Much more reliable engine at the cost of a bit of HP.
or
-Replace valves, have heads checked and leveled, install new MLS headgaskets and the timing kit above.

UPDATE: So i went out and pulled the timing cover and everything in it's way. The belt is completely intact, and all the marks lined up perfectly. I tried cranking it and noticed the cranking had evened out (not speeding up and slowing down as before). The engine started and ran fine almost immediately!

I noticed a fairly loud ticking sound coming from the passenger-side head. It seemed to quiet down after about a minute of running. I even revved it a few times and there was no missing or stumbling or anything.

Is it possible I had a valve stuck open on the passenger-side head causing the compression loss and weird cranking? Maybe after some cranking it closed finally and was able to start? Would the ticking sound over there support that theory?

If so, what can I do about this? Can I try running some kind of cleaner through there like Seafoam or something? Of course ideally I need to pull the head and take a look at some point, but I really can't afford the downtime if I can avoid it right now. I'd be in a better position to yank the motor this spring or summer as I was planning to do so anyway. I think I botched the main seal job when I did the clutch and I have a leak so it has to come out anyway.

Thanks in advance for any help or advice!

'dropped' valve guide is a possibility

a new to you EJ25 with extant issues is about the riskiest subaru situation possible but i'd hesitate jumping immediately to the worst case scenario every time. won't start - timing belt broke. i heard a noise - the head is scrap. get some information on the table and see where you're at:

piston slap? benign, turn your radio up louder.
injector? swap with the other side to see if the noise moves.
power steering/timing pulley/alternator bearing?
isolate the noise better and rule out some common and easy things.

and of course there are more ominous things but these are easy and we'll get there quick enough.

idosubaru, so far so good since the issue resolved itself. I'm fairly certain the tapping/ticking is coming from the passenger side head. It sounds very valvetrainy. However, for now it's only doing it when cold and isn't affecting engine performance. I'm hoping it can hang in there until this summer when I pull the engine to fix leak issues.

piston slap often gets less noisy as temps go up.

wet plugs from moisture (maybe oil too?) can arc until heat drives moisture out....not sure everyone would hear it though.

Is it possible to do a compression test on these in the car, or do you have to do it with the motor out?
