Review on PAC-1218 Valve Spring: GM LS-Series Compatibility, High Performance Ovate Beehive Spring (16 PCS) by Jared Winebrenner

was literally installed and started 6.0L LS in Silverado. I never left my area. I ran it at near idle for about 2 hours just to break in the rings and get even bearing wear, check for leaks and warm it up. TO STOP! Towed home, my house was less than 1 mile away. I removed the valve cover and what do you know? THE VALVE SPRING BREAKS IN HALF. Valve abandoned and destroyed everything. New pistons, new rocker arms, metal everywhere, and that's why CHEAP CHARACTER, BADLY MADE FOOLING FEATHERS! I KNEW BUYING IT WOULD BITE MY POP BUT IT'S NOT A RACING ENGINE OR CAR SO I THOUGHT IT WAS OK FOR A SHARE APP! Boy was I wrong! SHAME YOU ARE SELLING THIS CHARACTER! I wish I could leave 0 stars out of 5!
