2004 Jeep Cherokee • 119,000 miles

My timming chain tensioneer broke on right bank on my 4.7L and it appears to have jumped time on right bank. Timming marks dont line up does this bend or damage the valves or pistons? On the 4.7L motor when this happens? I was going to replace the chains and tensioneers but I was in hopes I wouldnt have valve or piston damage and have to change or repair head on that side as well. Any thoughts

You should be fine. I don't think they hit on this engine.
