I've been looking for some parts for my Soarer for a while now, just to kill time (Whole other story) Anyways, I ran across a crank scraper for it and wondered if anyone is doing this for our engines?
For some of you that don't know what they are or what they are for:
As the cranks pick up in rotational speed, they create a vortex of wind inside the crank case causing the oil to "cloud" up at times. This leaves deposits of settling oil on the crank, supposedly increasing rotational mass, and that extra little bit of force for the crank to push though the cloud of oil at the worst of times. The point of the scraper is to simply remove the deposit by scraping it off (who knew), it also prevents the cloud of oil from making its way past the crank if positioned correctly. Although our oil pans come stock equipped with a baffle, is it likely that they're doing a good enough job of holding that extra little bit down? This is just a thought and question post so don't be overly critical on me.
Here's some pictures of what they really are and the point of them.
Although the one in those images is obviously way out of scale, you get the idea.
Here is a site that supplier of these for our engines, they also have windage trays Mitsubishi If you scroll down about half way you'll see them for our engines (2 & 4 bolt)
The windage tray really caught my eye as something useful though. it not only works as a pre-screen for the oil sump, but it drastically reduces the speed of the oil "flinging" off of the crank, which can produce cavitation and aerating of the oil in the pan.
