    Check the tension of the other other injector hold down bolts, if one was the loose the other probably will be too.

    I would definately check the bearings, especially the upper big ends, any low oil pressure codes combined with fuel in the oil and you should be checking the bearings.

    As long as the crank was in good condition to start with it should be fine, I have seen some pretty bad fuel dilution before and most of the time the bearings are polished and get replaced as a precaution but the crank is fine.

    Crank looks good as well as main and rod bearings. New cup is in, injector seems to have went into the head good. I smoothed out the burrs on the head and no o-rings got caught when putting it in.

    Hoping everything is good and the injector will seal ok. Gonna be running the overhead tomorrow after I go pick up a new injector rocker.

    Fired it up today and it idles pretty nice. A few of the exhaust and intake valves were pretty loose but all the other injector adjustment heights were pretty well spot on. Might take it for a road test tomorrow.

    On a side note, I hate Cat oil pan gaskets!
