First, I want to thank everyone who enters this thread because my Subaru knowledge is limited. Someone I am close to has her 2009 Forester going in for the 3rd set of cam seals in less than a year. First time, around 10 months ago, near 147k, a cam seal failed and it was pushing an incredible amount of oil out. Car went in for a timing belt/tensioner/cam seals to a supposedly competent shop (though the owner expressed how much he dislikes Subarus). First failure was an original cam seal. About 6-7k later it starts dumping a gross amount of oil again. Shop fixed it and replaced the oil soaked timing belt too, no charge bad cam seal. Now about 4k later, oil pouring out again. Same side leaking as the two times before, above the oil filter.
Are these seals difficult to install correctly? Any underlying problems that cause this? The engine doesn't seem to be making any excess blowby/pressure. By Subaru standards, the engine seems to be in pretty good shape.
