When upgrading valve springs, increasing lift and modifying other engine components, the valvetrain load increases beyond where the factory VCT system can maintain stable, timely control of the camshaft timing. This loss of control could lead to piston to valve contact in the worst case but generally manifests as DTC codes, check engine lights or timing system rattle. \u003c\/p\u003e\n\u003cdiv\u003e\n\u003cstrong\u003e💡 DID YOU KNOW?\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eFactory VCT phasers are unreliable with upgraded cams.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOnce you upgrade to stiffer springs and higher lift cams, the factory VCT gears often fail to reach or hold their target position against the extra load.
