    Tap on the retainers with the back handle of a hammer. You should hear the valve go in sligthly, it may take 2 tries sometimes. The single groove keepers make this much simpler.

    That impeller bolt is part of the oil pump shaft, probably a good idea to replace as well.

    2007+ OEM 4tec valves issues?

    Any issues with the newer seadoo 4 tec valves from 2007+? Would they be okay to spin up 8600Rpms if stock sprigs are used with titanium retainers?

    Yes the cylinder head can be removed without pulling the engine.. It probably caused damage to the piston as well..

    I did return a full set of Connection rod bolts back to SBT in the past.. 2 of the 6 bolts were cross threaded, they wouldn't screw in by hand.

    I would try finding a newer block. It looks like the thrust washer ate far to deep into the block. It will give you issues with the main bearing clearances..

    I was recommended to use 60s or 80s for a ET137+4mm for a riva tune and Siemens ECU.. Wondering if the 50s would cause less starting issues (Flooding engine) when trying to start the engine hot??

    Not checking clearances is 99% of the time why rebuild engines fail.. Especially with the high reving 4 tecs.
