alex said:Grumpy I read the thread on windage trays and I,m rather interested in installing one but I won,t be installing ARP main cap studs or getting the block line honed, so obviously Im looking to install a windage screen thats part of the oil pan itself, I really don,t want to spend $80 on the windage screen and want to look at options, any ideas?
There's lots of options and careful measurement and a bit of thought goes a long way here!
the oil level drops by about 2 quarts in a running engine as theres about 2 quarts circulating in the oil passages and in the heads and lifter gallery when its operating, I generally look to have the oil level about 1/2" up on the main caps while the engines sitting, and because most engine sit in the car frame at an angle I'll point out that 1/2" up on the main cap is measured on the rear main cap,and the arc of the windage tray should be just about 1/8" larger in diam. than the rotating assembly arc. so thats where in the oil pan the windage screen needs to be bolted or welded
but I also use a windage screen and crank scraper to control oil return rates to the sump.
you might want to consider installing a windage tray and oil accumulator ,
the pictures below may be useful to give you ideas, and rolling perforated screen on a gallon paint can can help bend it to shape, tin snips, a plazma cutter or a dremel can be used to cut screen

materials required are easily obtained, careful measuring and fabrication can produce a very effective windage screen as a component part of the oil pan design.

perforated steel from larger speakers, computer mounts etc can be salvaged and reused for fabricating windage screens if you have some ingenuity skills
