Yeah only the dohc vtec engines (h22, b18c,b16a) have oil squirters. The ls has a hole in the rod that allows oil to lube the wrist pin, along with the oil the rings scrape down the cylinder and into the holes in the side of the piston.I'm sure some oil splashes up to the bottom of the pistons, the ls doesn't have the windage tray like the gs-r..
