Thats what I'm saying. Timing chains do not wear-out easily. Maybe I should have stated 200K+. If it was a timing chain, it's not too likely to die quietly, the driver will hear something else than wind noise for a few seconds because to opposite bank is still pulling if this is a OHC mill (six sprockets).
This tread, are we posting about a OHC (4.7) engine or what?
Like wise, due respect to you 05RamMan; Tensioner has ONE duty, Quote from the DC Service Manual. "Nylon covered spring steel presses on the chain maintaining correct chain tension". THERE ISN"T ANYTHING TO BREAK ON THE TENSIONER. It will be the last thing to malfunction mechanical on the engine. The chain WILL NOT JUMP with this small amount of slack without the tensioner especially if you are cranking w/less than 200K. This would be an all diff story if we were discussing a belt problem. Everyone remembers their last engine build how installing that tight chain is a real -itch in just trying to align the timing marks, one tooth over will screw one's day royally.
I'm still believing with what little has been stated here, it is electrical.
Again, There WILL not be bent valve stems, butchered cyl walls and piston heads unless it is a OHC w/momentary free spinning cam. If there is a loss of timing, there would likely be some bucking, bad firing, some noise then wind sound to a stop.
OK, 05RamRam, nough of this pissing contest.
Hey! where did the man in trouble go? If he has left us, I'm going out back and clean some fish.

 

Sorry guys I'm here, been working alot! I did find out the problem and its way worse than I thought. The chain broke, bent all the valves and prob busted some pistons. Its not under warranty anymore I did find a 22k mile hemi for 1,700. I guess I'll go that route. Thanks for all the help!

 

WOW the chain broke???
Not heard of that one failing on these Hemi's
That's one cataclysmic failure right there.
Good luck with the replacement Hemi bro.
Al.

 

OneHemi, Now that I think about it, You are correct sir, My apologies. I am thinking of the mode of timing belt, Where if the tensioner spring can loosen the timing can jump. It has been a while since I worked on an engine with a chain. Its all good OneHemi, lol.

Blue, That bites,Takes alot for these chains to break. Good find though, Was it out of the same year? May I suggest you take this time with the engine out to do any mods you may have ever wanted to do to the engine. CAM, Headers, Stonger Springs, Sodium valves, porting... etc... lol.

 

Blue, this is very interesting. Would you be so kind and let us know what engine size you have thats toast? Maybe you can take a few pics of the failed components?
As AbArmBy stated, this is not heard of with HEMIs. Must have been a chain fluke.

 

BTW, I hope you insisted on seeing the broken chain, Id personally have to see it to beleive it myself if they told me my chain broke.

I know its hard to beleive a hemi broke a chain, however, 1st post, "06 hemi ram". Its gonna be a 5.7 with MDS

BTW, OneHemi, love your sig.

 

05RamMan, I know. I kept reading it but, 5.7s do not have OHCs like the 4.7s. Thats what has been so confusing since the tread started. I thought all HemiS were 5.7 and higher. My DC Service Manuals do not show anything differ. ?

 

I went back a re-read the thread and see what your getting at, 5.7 definitly don't have OHC's, they are OHV/Pushrod engines. I actually didn't know the 4.7's were overhead cam engines as I have never actually seen one up close. As far as I know all the "New" hemi's in are trucks are only 5.7 or up and I am not even sure if the 6.1 is an option in the rams.

 

I did go by and see the timing chain, it was broke and the strange thing is that the chain wore a groove in the block, but I never heard it doin it. Must have been doing it for some time.
