    a good reason to change the oil yearly even if you only put a few hours on it.

    might have dropped a valve at high rpm

    don't dissemble it unless you are planning on fixing it, engines in a box really hits your resale price hard

    There was a known issue with the timing chains in the 07-08 model years. Changing oil more frequently would not have fixed a bad batch of chains. If you're familiar with rebuilding these motors, you can still come out ahead by rebuilding it. If not sell it and recoup some of your loss or part it out. Its not worth much as it sits, $500 -$750 would be a good price.

    Looks like my bad luck just got a lot better.

    Looks like you got lucky and didn't bend any valves, or did you? As a minimum, you'll need a new timing chain, rod bolts, and head gasket. You need to pull the crank to install the chain. You can reuse the case bolts and the head bolts if they spec out. Some say change the head bolts but I've reused them on stock motors. You'll need to check the timing chain guides, there s stop that often breaks off the block when you pop a chain. It can be rewelded to the block. http://greenhulk.net/forums/showthread.php?t=263827

    Not sure if I bent any valves. There’s 2 that maybe questionable. Does this mean the motor has to come out to put a new chain on?

    The guy I bought it from apparently flooded it with the water hose before starting it and it sat for a couple of weeks before he cleaned it out. Not sure how often he changed the oil. I am not familiar with rebuilding these. Can I just put a new chain in and head gasket and be done or does the motor have to come out?

    The motor has to come out and the have to split the crankcase to get the new timing chain on. I'm pretty sure you also need to remove the rod caps to lift the crank enough to get the timing chain on. May someone can chime in if they've done it with removing the rod caps. No need to start another thread.

    Exhaust valves on #2 are bent for sure. Probably all 6. Will have to pull motor. Can replace chain without unbolting any rods but will have to remove at least one oil squirter to lift crank high enough to get new chain in.
