3.7 has a knock pulled valve cover and found bent intake valves and loose timing

Yep!... Had a 4.7 (basically the same engine, just 2 more cylinders) in a Durango that dropped an exhaust valve seat... Replaced the engine cheaper than repairing it would have been!... Now this was a good salvage engine... With warranty... It's going to be high dollar either way!

She had a backyard mechanical mess with this. From what I can tell is he missed timing and the cam bent valves
