I did a search both on Google and on these forums, but I didn't find an answer to my question.
I'm designing my own crank scraper/oil pan baffle system, but I think I've identified an inherent deficiency in most designs.
Our engines are tilted back about 12*. All of the scrapers I could find have the scraper mounted parallel to the oil pan rail. Here's the issue, part of the scraper is found on the down-stroke of the crank throws, which is in the front of the engine. If the scraper is parallel to the pan rail, then this means the oil that is being scraped off of the crank will want to flow back toward the spinning crank. Typically the scraper is mounted directly to the pan rail with only a few drain holes. The other part of the scraper is on the back rail, which is on the upswing of the crank. Now, with an oil pan that doesn't have a baffle system to prevent the crank from sucking oil out of the sump this makes sense, but with a baffle that blocks the sump from the crank it's not as effective, leaving the front doing the majority of the work.
So, to address this problem I'm planning to mount the front part down past horizontal to force the scraped off oil to flow away from the crank. Has anyone seen this done, or done it themselves? Thoughts?
