Subaru Head Gasket Change.

Like I have posted, and will continue to do so as time and information allows is that it seems that Subaru has finally gone to a MLS Head gasket for the 2010 Outback.

above are the differences between a semi closed and open deck block, and while I wont know until we take one apart, it appears that Subaru is also using a semi closed deck block in the 2010 Outback.

Thanks for reading and watching

UPDATE!

We have replaced head gaskets around the 120 to 140k mark on another 2010, and one 2011.  The engine block was the same open deck block that Subaru has been using for years, there was increased surface mass on the cylinder head area and the gaskets were not leaking externally but instead had failed internally.  I had made mention on another post that we had done a valve job on a 2010 that was in a front end accident, and did verify that car had a semi closed deck block, I did not however verify the block # matched the Vin.
