Default Valve seals, possible without removing heads?

I just got my new motor in and running... but it looks like I must have torn a valve seal when I put the valves in. I really dont feel like pulling this thing apart AGAIN, but I cant really see any way I can get the springs off without a big c-clamp style remover... anyone got any thoughts?

I assume you have an STI engine??? Their is an engine forum here and scooby mods.com sometimes has better "how to" info.

You can install new valve stem seals without pulling the heads. I would pull the engine out and perform this work on an engine stand.

You may need Subaru tool # 499718000 for the valve springs, and Subaru tool # 498857100 used to properly install new valve stem seals. You also should use an air compressor to keep the cylinder pressurized to prevent the valve moving while your replacing the stem.


Have fun.

At least in the boxer engine, you don't have gravity demanding the valve drop into the engine. Did the seals in an old Buick engine once and for some stupid reason I released the air pressure holding the valve up. Things got expensive quick.

K I'm getting confused... This doesn't make any sense.

Cylinder 1:


Cylinder 2:


Cylinder 3:


Cylinder 4:


Obviously I need to switch to a colder plug, but the oil is what's puzzling me. Plug 1 clearly has oil on it, but I ran a UV dye in my oil, and there's no oil in any of the intake tracts, but there's oil in the exhaust port for cylinder 3, and not cylinder 1!



Blurry picture, I know, but it's hard to take a decent picture when you're holding a UV light in one hand and a UV filter over your camera lens :P

Any idea why this would be? There's no evidence of oil getting into cylinder 1 other than the spark plug.
