Crank scrapers or plate...?

I get that. I use a crank scraper. I don’t run Pro Stock. I carry way more oil pressure than I normally would.

That should be a big clue as to some of what the crank scraper does.

99% of the people on here don’t use one because they have never been told the benefits of a crank scraper or don’t understand it.
1st motor I built for myself had a scraper. Made it out of duct metal, it bolted between the pan and block.
The guy teaching me at the time 'Leonard Layman' a swed ..cross drilled the crank too. I still have the scraper hanging on the wall. I was 17 years old. Long *** time ago.
