Filing in context
The Lubrication system is the most frequently cited component category in this archive, appearing in 9 of its 4,890 filings. This filing is one of 7 Subaru notifications from 2004 in this archive. For scale, 4,831 of the 4,890 filings in this archive report a larger number of affected vehicles.
Defect
On turbocharged manual transmission vehicles, the cover mounting bolts for the oil control valve (OCV), which hydraulically controls intake valve timing, have insufficient clamping force. Under sustained high-load, high-rpm operation, negative pressure inside the engine increases and the OCV gasket deforms, further reducing bolt clamping force. The bolts may then loosen, allowing engine oil to leak. In the worst case, this may result in a vehicle fire. (Note: This filing adds newly identified vehicles to the recall originally filed on September 15, 2004, under Notification No. 1220.)
Corrective action
On all vehicles, the OCV cover bolts are retorqued to the specified value.

状況
ターボチャージャー付手動変速機車両において、エンジン吸気バルブ開閉タイミングを 油圧で制御するためのオイルコントロールバルブ（ＯＣＶ）のカバー締付ボルトの軸力が低 いため、高負荷高回転を継続して使用した場合、エンジン内部の負圧が増大し、ＯＣＶのガ スケットの変形により当該ボルトの軸力が更に低下することがある。そのため、当該ボル トが緩みエンジンオイルが漏れ、最悪の場合、火災に至るおそれがある。 （備考） 本届出は、平成１６年９月１５日「届出番号１２２０」のリコール届出に、新たに対象車 を追加するものである。
改善措置
全車両、当該ボルトを増し締めする。
