Oh, the horror...
I'm sorry to hear of the ill-fated events that befell you. I hope it's not the same for GMtard89, but I suspect some residual 'bad sh@t' is inevitable. I don't know for sure, but I think that dipstick is spring steel; that's pretty hard stuff, no? The good thing is that GM is starting with uncontaminated oil, sans what just happened.Do you have a flat tappet cam in that engine? I wiped out one lifter which sent "glitter" throughout. I replaced the lifter, changed the oil and filter a couple times. Then a couple months later, wiped out 2 lobes on the cam, 1 was because of a collapsed lifter (from glitter stuck in it). I spent over $2K on a roller cam, lifters, springs, seats, keepers, etc. Ran for a couple weeks, then spun a rod bearing. Now I have a big paper weight or a small boat anchor. I just ordered a 383 Blue Print short block to the tune of ~$4700 with tax and shipping, all because of some glitter in the oil. This may be an extreme case, just saying.
Drop the pan, clean it out, hospital clean, maybe even leave a couple magnets inside, and keep changing your oil, send a sample out each time to see if you're winning. Hopefully you'll save it without too much expense. YMMV
I hate to be a Debbie Downer, Good luck!
Edit: This can happen to a roller cam too.
Drop the pan, indeed, and change the oil lines if you have a cooler on her. Cut open the oil filter for a peak before doing anything else too. Sending the oil out for analysis would be my choice as well. We did it at the HD dealerships I worked at often.
I know firsthand how much carnage can happen to a Harley engine from something letting go in there. You'd be very surprised at what can happen, and they still run, the tractor engines that they are. Lifters are very susceptible to invasive foreign metals that come to visit, and so are piston rings.
I'll wear the Debbie Downer tag and pray for the best.
