It sounds like you may need a timing chain tensioner.
I looked on e-bay and found a kit which includes an "upgraded" tensioner, and includes all the pieces, for only 60 dollars.
God bless your efforts.
Both the 2.2 and the 2.4 engines use a chain, not a belt. A chain could still be faulty, but I doubt it would jump teeth unless the tensioner failed to keep it tight.
Hello! I do not believe the engine "jumped time"...But merely overheated...Fill it back up with 50/50 and a little water...Start the engine and visually look to see where the leak is...Send a comment ...Guru...saailer
If the timing belt (chain ) broke or jumped the car would not have restarted after your son shut the engine off. (The motor would have stopped on it's own.) Timing belts are an issue with most modern cars and if the motor is what is referred to as an interference engine there will be valve damage. The other possibility is that some components from the butterfly valves in intake manifold were sucked into the cylinder head causing damage to the cylinders , pistons and valves. No matter what the cause its going to cost a lot to repair.
I have a 03 pontiac sunfire that jump time. It also bent the intake valves on the head. I got the head repaired and got a new timing chain. According to the vehicle manuel repair book I am to align the intake balance shaft and the exhaust balance shaft with the crankshaft as well as the crankshaft to the cam intake and exhaust sprokets. This has all been done. I even did the tensioners on both cam and balance shafts according to the book. When I go to start it it jumps time. So I do it all again but this time I crank the crankshaft using a socket wrench and as it turns I see it starting to bind and then it gets loose on the right side where the intake valves are but I do not see where or what could be causing this. The chain just gets loose on one side ( Not tensioner side). I am confused please help.
If the timing chain jumps will this bend the valves???
