I have a 2000 jaguar 4.0 s-type recently I drove my car about 10-20 miles roundtrip parked it and came out 10mins. L8tr tried to start it and it seemed strange that I had to push the pedal to start it revved it and heard a popping sound shut it down couldn't figure what was wrong so I pulled the valve covers and found out the secondary chain snapped. My question now is how can I find out if I bent a valve without removing the head I took a camera and looked at the pistons in each cylinder and they look fine I took a breaker bar and a socket and turned engine with no problem I can't check for compression because I haven't replaced secondary chain and tensioner yet any feedback thanks oh and the popping noise was the broken chain cracked a hole in the valve cover can that be repaired or should I replace that as well thanks again."Desperate for diagnosis"
