I have a 2004 Impreza TS with 140,000 kms on it and recently noticed some coolant on driveway that looked like it had bubbled up and was kind of a pale green color (sorry I'm not very technical). I took it to the dealer and was advised I have a leaking head gasket. Cost estimate was quoted between $2,000 to $3,000 to do this repair (out of warranty). When I contacted Subaru Canada I was advised they would cover $1,000 in parts bringing my repairs to $2,200. I understand the labour involved is extensive but does anyone know if $1,000 parts sounds accurate? Many of the posts on this thread refer to previous generation engines, so I'm not sure how common this issue is on post-2003 engines.
