The 3.0L Vulcan engine in the 2006 Ford Taurus is a non-interference engine. Thus, when the timing chain breaks, there will be no piston or valve damage as a result of the cam and crankshaft getting out of synchronization. The "steam" you see is probably some combustion gases coming back up through the intake from any open valves that were trying to fire after the chain. broke. That isn't saying that there cannot be damage....you must look inside the timing chain area. There is the possibility (albeit remote) that there could be some damage in that area, more likely if you have a manual transmission. But you probably will only have to replace the timing set and chain tensioner to get it back up and going. Plus a few gaskets and some fluids of course.
I assume it's your timing belt, not a chain, which rarely, if ever snap. Depending on the make of the car and the engine you may, or may not, have serious engine damage.. DO NOT ATTEMPT to start the car, have it towed to your shop of choice. If there is no engine damage a timing belt replacement generally will run you 2 or 3 hundred bucks...if you did serious engine damage you may have to decide if the car if worth the money to have it repaired. What you need to know is whether your car has an "interference" or "non-interference" type engine.. In an interference type engine if the timing belt breaks the valves will "interfere" with the pistons as they travel up if the timing belt breaks, which results in generally catastrophic engine failure.. non-interference engines generally suffer little or no engine damage with a broken timing belt.. I broke a timing belt on my 1990 Toyota Supra going 70mph, but it was a non-interference engine and after having the belt replaced it was fine.. here is a good list someone put together on what type of engine is in your car.. you should find the engine type either marked on the engine or on a label under the hood, or the owners manual.. good luck. http://yourcarangel.com/2014/07/interference-engines-complete-list/
it depends if you are the first owner and it has 80,000 mile is a timing chain that noise is the pistons hiting the valve dont try cranking your car cause it could damage your valves and is gonna cost u more cash
When the timing chain breaks the cam quits turning. Any valves that are open, remain open.
If the motor is turned over trying to start it or bump starting it in gear, the pistons come up and
hit the open valves. Bent valves are common. If it is a 4 cylinder only a couple valves will be open
at a time so you may damage 2 or 4 (there are usually 2 per cylinder so a 4 cylinder has 8).
You could replace the chain, make sure the timing marks align with eahother and the chain but
just getting the cam and crankshaft to alignment could cause some damage. Good luck. I did
it to mine once. Bent 4 of the 8 and had to pull the head, sent to the machine shop and reassemble.
I tried to bump start mine down a 2 mile hill. Ohh well! It's fixable.
The 2.4L four has a belt and is not an interference engine according to the Gates timing belt application chart for your vehicle (check it out on Gates.com.) The 2.7L V-6 doesn't show that it needs a belt--so it has either a timing chain and gears or just gears. If the belt broke on the 2.4L four, you should be able to put on a new belt and go. The engine should not be damaged.
If the timing chain on the V-6 broke then engine damage may have occurred. Chain engines are sometimes not listed as interference because breaking a chain is so rare. The damage would probably be bent valves and damaged piston tops. The labor involved in repairing all that might cost more than just getting a rebuilt engine and putting it in.
There is no specified mileage. Timing chains last a lot longer than timing belts and the rate at which they wear can depend more on the frequency of oil changes and engine use or abuse. The general rule of thumb most shops go by now; if it's getting noisy, then it's time to pull the timing cover. Often times it's not the chain itself, but the chain guides that have failed. Either way, a timing chain job will involve new guides, tensioner, and chain. It's an expensive job, no need to rush into it unless you know you have something coming apart and noise is your first indicator.
maybe, maybe not. If the chain only slips a link, this will not happen. It depends on how it fails, and you never know exactly what the damage is until you replace the chain and try to start it. If you're sure there is SOME damage, then you go ahead and pull the head off to assess the cost before replacing the chain. The damage can range from a bent valve to busted pistons. If you have more questions, please let us know.
No,the V6 engine is not free spinning. If the timing chain breaks, leaving the valves open as the piston moves through its travel,there will be damage to the valves.How much damage will depend on speed of engine and length of time it ran. You can perform a leak down test to check the condition of the pistons and valves. It will tell you if the valves are not sealing,without having to take it apart. Thanks,Chuck.
