Doesn't have "lifters" as such, hydraulic or otherwise.
Valve clearance is manually adjusted - its a service item.
Have a look here

Could need the valve clearances doing but could also be :
Exhaust gas leak from exhaust manifold/header that side.
Spark plugs loose - gives a loud tick as the compression blows past the loose plug.
Noisy injectors.
Hope it's something simple

IIRC, it's not part of the Service Schedule, normally done when the engine is rebuilt.
The exhaust valve clearances do tend to get smaller as the mileage of the engine gets higher( 90k+ ) due to valve seat recession/micro welding of the valve seat and face.
SOHC N/A engines generally have screw and locknut adjusters and it's easy to pull the cam covers and adjust the clearances as I did on the wife's Bugeye N/A wagon recently - Inlet clearances were loose and exhaust clearances were 0.005" smaller than the minimum spec but the car has done a whopping 210,000 miles
UK models which use the Outer bucket shim can be adjusted with the engine 'in situ' using the Subaru service tool.
All under bucket and selective bucket type engines require the cams to be removed to adjust the valve clearance.

You bolt the tool in place on top of the relative cam cap using one of the cam cap bolts, and wind down the forked arm of the tool down onto the edges of the cam bucket you want to remove the shim from.
Once the bucket is depressed enough, the shim can be flicked out of the top of the bucket with a small screwdriver and magnet.
Will see if I can get a photo of it in action.

I just did mine with two screwdrivers 👍
No special service tool available.
What is the recommended valve clearances on the large 99-01 outer shim type?

As you are in the know.
What is the best way to check piston to valve clearance on a new built impreza block?

Sorry for the hi jack. Is there anyone who sells the v3-6 sti underbucket shims?
edit - Just seen them in importcarparts. I swear they weren't there the last time I looked.
