In my country some cars are returning to Toyota due to high clearance on the valve shimmings because Toyota doesn't adjust the shimmings to the right spec after replacing the valve springs.
The result is a high metallic noise like valve tapping. I guess the recall procedure doesn't include it, so they don't measure it

If Subaru/Toyota techs would follow the specified recall procedure you wouldn't have those issues as the recall precedure clearly tells them to measure and shim as needed;

7) Measure and record the cam clearances following the procedure in the applicable Service Manual.

IMPORTANT NOTES: The purpose for performing these cam clearance measurements is to
compare the “before” and “after” values and confirm there was no change.
• If the clearances are out of specification, obtain the required shims for installation prior to
reassembly.
• If the clearances are all within specification at this point but after reassembly, some are
found to be out of specification, it is likely some of the shims were miss-positioned during
reassembly. CAREFULLY Re-adjust as necessary to insure all clearances are within the
following specifications:
Standard values (cold engine):
○ INTAKE: 0.10 to 0.16 mm {0.0039 to 0.0063 in.}
○ EXHAUST: 0.21 to 0.27 mm {0.0083 to 0.0106 in.}
8) CAREFULLY remove the timing chain cover, timing chain and all related components following
the existing procedures in the applicable Service Manual.
