I had no luck with the Suby conditioner, but then my gasket was torn. I also paid a lot less than the $30.00 this Amazon ad claims is the list price, as I recall at the local Subaru dealer it was $2.50 a bottle. The FIRST head gasket replacement on mine lasted 300 miles-yes, I said the first. I was not happy that at 300 miles I developed another leak, this time around one of the head nuts. I was told by a couple of respected VW gurus that re-using a head may not work, as cracks can happen around the head stud passages. I purchased a "used" head from Go Westy for $350.00. They said it was used with very low mileage but it sure looked brand new to me. The second head gasket/head replacement went a LOT faster than the first one, lol. That repair lasted at least 5K miles. I say at least because I then sold the van. As far as I know it is still going strong. Jeff
