Oh man, well if the timing jumped your pistons probably destroyed your valves, which would cause no compression. Its possible if that happened your heads could be beyond repair as well, along with your pistons could have been damaged by contact with the valves, and thats where your missing oil could have gone.
The only way to tell is to start tearing it down, and thats money.
I had this happen with my wifes escape, it was cheaper to put a new engine in than repair the old. But unfortunately i had to pay the labor of the diagnostic as well because I too could not believe the engine had suffered such damage literally 2500 miles out of warranty.

now... if i had to be in that situation... and will have to consider replace the engine or rebuild... why not tear by yourself the top part of the engine and find what is the damage to the pistons or valves. then you will be able to make a more informed decision in what step next. either have your mechanic or yourself to change the timing belt, consider a rebuild o replace the engine.

in the meantime, you may have to start looking for another engine.

Thanks everyone for your support. I'll try to look for any damage today and get back to everyone to let you know what happened

Went to he mechanic today. He has torn down front part of motor. The timing chain tensioner on drivers side is gone, chain is tight but sitting on metal. Passenger side is also missing tensioner, but chain is very loose.
Mechanic said that the tensioners can wear down due to heat from engine. This seems to be a problem w/ 2004 &up.
I was talking to my neighbor about this and he told me that he read an artical that stated if you run your motor w/ less than half a tank it can cause more heat from the motor, hence causing tensioner damage.
Anybody have any thoughts on this?

half a tank of oil, sure will create more heat. usually if you loss a lot of oil, you loss the engine because of heat and friction.

half a tank of gas, i dont see why would do any damage to the engine...

The half a tank thing... gas?
If so, thats not true. Cas only goes one way on these trucks and it wont matter unless its run right out.

As for the chains. This is not a 04-0? Ford problem, These long OHV chains are a problem on many modern motors. Sad but true

Older OHC engines mostly used a timing belt. And changed at intervals they were fine.

Chains have many areas they can wear, guides, chains stretch and tensioners fail.

I think I have changed one chain in at least every make of vehicle.

Now changing the oil on a regualar basis is very bad for all the parts related to the chains.

I would say if the timing is out a only a few teeth, throw the parts at it (all of them) and it will be okay.

See my thread on phasers and chains for part numbers and info on this

Best of luck

Less than half a tank of fuel? I can't begin to wrap my head around this logic. Your fuel is not what cools your engine, your coolant system does, antifreeze. Now if he meant half of the coolant level then yes, every engine would operate at higher temps.
The stock chain tensioners seem to fail because they leak and cannot apply the right tension. At least that is what i gathered from reading multiple cam phaser threads on here, and they all seem to let loose at the same area. I haven't yet heard anything about engine temp causing them to fail, unless your overheating your engine but your gauges would read high, have you noticed your engine temp higher than normal?

I would like to thank everyone for your replies. I din't think the gas level would have anything to do w/ heat, but I wanted different opions on this.
Update: my mechanic called me today, said that the bolt that holds the tensioner to the oil pump broke and messed up all four timing guides and the oil pump. He's gonna put everything new in and try to crank it up. Anybody hear of this prob before?
Keeping my fingers crossed it didn"t blow the motor!

picaflor

Lets keep finger crossed.

Having a chain is good, but when we use to have a belt, we replaced all this tensioners and thingys around 100k.... hard to check them from outside is now...

Thanks picaflor!!
