Cylinder head gasket replacement is something that many Subaru owners will experience, and it’s a service that we have discussed before in our blogs. What is unique about this particular service was that the left camshaft case was also leaking oil, and this is very uncommon.

The camshaft case on the 2005 Subaru Outback is sealed with a special high quality silicone sealer and it rarely fails. While the heads were off it was a matter of taking the cam case off, cleaning all components and carefully removing the old sealer. After applying the new sealer and reassembling the case to the head this leak was solved.

Head gasket replacement is synonymous with Subaru although it is not always needed. The issue is not present on the H6 engine and that is a good thing because the cost to do H6 head gaskets is triple the price of the H4 2.5 Liter engine. Are head gaskets better these days than the past? Only time will tell. We were told many years ago that Subaru had corrected this issue but we still see failures. To put things in perspective, most cars have some issues and while head gaskets are a significant one, Subaru’s are still great, reliable cars in most aspects.
