    I'm doing a head gasket replace and a bit deep in it. I didn't see the part early on (gasket masters vid) about loosening i the flywheel/harmonic balancer and now I am at that stage. So I am wondering if anybody has ideas or been in this situation to help out. Thank you!

    I'm assuming your talking about removing the harmonic balancer; because the flywheel is on the other end of the engine and inside the transmission/transaxle bell housing?
    You'll need to use a 1/2 inch impact wrench to buzz the bolt off and possibly a harmonic puller. You can borrow a puller from any chain auto parts store - don't know if they'll loan you an impact wrench - but I believe the sockets are available.
