First time I heard of a crank scraper, I thought it was some kind of drug paraphernalia. I installed one on my 22RE motorhome, which is brutalized by long, steep mountain pass and National Forest roads while under heavy load. Tossed the idea around with EB before I got it, and he was mildly supportive of the idea. Much research convinced me it was worth the $50.

Oil pressure increased on those hard uphill runs. Engine seemed to have a little more jock in its strap. The guy at Ishihara-Johnson is a cool dude. I'm happy I did it. If nothing else, the engine ain't blown up yet.
