Dodge hemi engine light. 4x4

[Monica B]

Hi, looking for advice for my friend in Calgary.
2012 dodge hemi 4x4. 130,000 km
Engine light came on. Engine is running rough.
He took it to a mechanic. Mechanic saw code
8 and 9. Friend not exact sure of those codes.
Mechanic changed
cam shaft sensor and crankshaft sensor.
No change. Mechanic thinks timing chain might
have jumped a cog. And wants to take that apart
for $1100 dollars. Maybe my friend should take it
to a dodge shop in Calgary?
Any advice is appreciated. Thanks

There’s the issue right there, Take it to red deer😁
Seriously though I would get a second opinion as it could be something very simple but than again I don’t know a dodge any better than a ford. I’m guessing dodge runs a rubber band for a timing chain

You guessed wrong. It's a chain.

I would have a Dodge Dealer read the code , but this is what mine was. It was idling rough and hesitated when you stepped on it. If your timing chain/belt jumped a cog or two you would likely smack a piston with a valve pretty quick.

Code PO108.

Thank you for that info.

Just went through a similar problem on my 2011 Ram with a 5.7 Hemi.
Turned out to be a broken valve spring.
This is a common problem on the earlier hemi's.
Do a google search and you'll find lots of info on the problem.

In my buddies it was cylinder 1 & 2 partially firing.

I was hoping it was just a broken valve spring when my 2011 hemi acted up last summer, but it turned out to be a badly worn camshaft lobe on one cylinder.
A considerably more expensive problem to fix.
As KnifeFan007 said, check google as both things seem to be relatively common events.

that is not enough information, the code will be a PXXXX. If you have that number people might be able to help you.

The timing chain is a chain

Thank you. I will see if I can get the codes.
