    I was like.. spray it down with carb cleaner??? But I figured I'll soak them in Seafoam to see how well it works. I've never tried it, just heard a little. Hopefully the carbon comes off. They sat since last night. I'll go check on them in a bit.

    I soak them in carb cleaner overnight and then scrub them with a toothbrush. Worked great last time.


    Are you sticking with OEM 22T pistons? :ugh:

    hehe these are '98 2.5L DOHC pistons. Sorry for not listing what they are.
    These are going back in my Dad's '98 Outback.

    The rebuild on my Dad's '98 Outback:
    resurfaced heads and block decks w/ fresh cylinder hone
    NEW ACL Race bearings
    NEW Std rings
    NEW seals/gaskets/o-rings
    NEW OEM head bolts
    NEW HG '98 2.5L DOHC

    It overheated and blew the HG between cylinder #2/4. Changed it once but didn't resurface it. Now it warped the head and the block deck. You can see the dark spot. The pistons did get steam cleaned though from the coolant. lolz

    here's what it looked like when I opened the motor.

    At least 2-3 more cars before I get to work on mine.... *sigh*

    Fuji, you're just too smart for these stuff. Most of the time I dont even know what you're talking about. I guess I can learn from just reading your posts.
