2006 Ford Fusion Problems

Uh......................I think that taking the 30 seconds to plug in the code reader would be a good idea...................the codes actually contain information as to what's going on with the engine.

After getting past the service manger to the mechanic I found out more. They did get a code of misfiring which he thought it was the coil pack. Wrong! He went further to do what they called a virtual test on compression not actual. This involved running the motor while the tester interfaced with cars computer. If he had of pulled spark plug and scoped it he would have found valves had kissed the piston. This may have caused more damage by running the car to do the test. I had to come down with my scope and check the front bank and show (use to be a ford dealer) the damage. After that they suggested to crank it up and drive it back into the shop where they would repair it for over $3500.00

I assume that you have the 3.5 engine as this is the only engine that the timing chain is on the water pump. Was the water pump shaft broken or the front water pump bearing failure the cause. Regardless what failed this an interference engine so if the cam timing chain jumped then you are going to have to take the heads off to repair the damage caused by the valves hitting the piston which I am assuming this from your comment "idling diesel motor sound" which I believe you are referring to diesel knock sounds. More info by having a bore scope exam of the low pressure cylinders will identify the damage within the cylinder. Even if there is no damage to the valves and/or piston even to change the timing chain is a major job because of the lack of room to perform the work in the car.

They keep calling it a 3.0 so I will have to check it out for sure. It does have the water pump being driven off the exhaust cam. I did scope it myself and found #5 piston with one small mark from exhaust valve. I was hoping that with this being the front bank it would be easier to fix. Thanks for the info.

If it is the 3.0 the water pump is driven by a belt from the camshaft. I have no idea how the water pump could cause the timing chain to jump since it is driven by an external belt where the cam is driven by a chain. If you go to this link it will show you step by step procedures to not only replace but also check the cam timing. I would also check the cam lobes and bearings for wear that could explain why the exhaust valve contacted the piston. If the head is still on you could do a leak down test on the cylinders and find where the cylinder leak is caused by intake valve air leaking out through intake, exhaust valve leak air leaking out through exhaust, leak through crack, blown gasket, piston, or rings you will see air escaping through radiator or crankcase vent. Good luck I hope this will help you finish diagnosing the failure cause. If I am able to help you more just post results and I will try to help. If you have to go in n check the timing then make sure that the chain tensioner are operating properly because if the cam did jump then you will have to find what caused the timing chain to jump as it is much more difficult for a chain than a belt to jump time.

The price of borescopes is getting cheaper every day. Harbor freight sells a model for about $150, and while you are there, check out the OBD2 code readers. They should be around $30. This will allow you to make an honest evaluation of your problems. The last service may have erased the existing codes, but the existing faults will reset the codes again for you. Good luck.

Thanks I do have one with a camera and light. So once I took it to the ex-ford dealer now service and used car sales I showed them on the screen of my scope that they should have found.
