Valve lifter noise on Subaru Loyale

Problem Description and Possible Solution

A hydraulic lifter type noise may be noted, often worse at idle. This can be caused by air being drawn past the oil pump seal allowing aerated oil to reach the valve lifters. Replacing the oil pump seals generally will correct this issue.
