I had regular service done to my car at clay Subaru of norwood massachusetts. The representative stated that the mechanic noticed some oil seepage from the head gasket. They recommended that I get the head gaskets replaced within a year. Since that time I have monitored the oil level and have had to replace about a quart in between regular oil change intervals. I am concerned because I know this represents major engine work. They quoted that it would cost about $2,000. 00 to replace the head gaskets. The car only had about 115,000 miles on it. It is a 2003 Subaru Forester that I purchased new in Dec 2002.
