Engine Tapping Sound From Left Cylinder Head On 2013-14
Subaru 2.5L Engines
When setting the valve clearnaces on this engine, the intakes should be set to .0039-.0059” and the exhuas should be set to .0078-.0094”. This is a revised spec from Subaru and is not currently published in the service manual.
IMPORTANT: Do not mix old and new parts together as it will become impossible to obtain the correct intake valve clearances.
