Dude, use an oil-shedding coating in there like is used on conrods??? 50 hp awaits you!
BTW I consulted with Elbowmotions on this snake oil vapor blasting treatment and Professor SS Kleine, Phd-PE-CPA-Esq-DDH tells me their non-destructive material testing indicates high potential for catastrophic bling. So you got that going for you, which is nice?
In all seriousness Souk will clean the case inside and out, all plugs pulled, piston squirters replaced, and rinse it 5 times. So he'll be fine.
