      Aveo head swap oil leak

      2004 aveo with used head installed from 2007 aveo and it is leaking oil between head and block on backside under the intake. i've discovered 04 and 05 has a single oil return and 06 and newer have dual return oil ports. Could this be my oil leak issue?

      That would be a “yup”.
      Did you use a head gasket for a 2004 or 2007 head?

      2004 head

      Must use a 2007 head gasket with a 2007 head.

      would a 2007 head gasket seal on a 2004 block?

      Maybe wiith a 2007 gasket. From my understanding, the back drain will just be blocked off if you use the correct gasket (the block is solid at that area on a 2004) If you use the 2004 gasket, the drain on the head won’t have any gasket fully surrounding it......thus the leak.

      After looking further at a 2004 block, I don’t see enough there for the rear drain to seal against....so please disregard my prior info. I think you can’t use the dual drain head on a single drain block. Sorry.
