Oil Return Screen Kit - Small Block Chevy

These Moroso oil return screen kits trap metal fragments or loose components from valvetrain failure to save vital engine parts from damage. The kits include stainless steel screens that fit over the oil drain back holes in the lifter valley and are held in place with the included epoxy. This Kit includes eight plugs to block the oil return holes in the lifter valley above the cam. This redirects the oil to the front and rear return galleries into which the screens are fitted returning the oil directly to the sump area instead of dumping it on the crankshaft with consequent increased windage and lost horsepower.
