Re: Valve Tick Issues
 

Now after reading I remember that mine clicks a little after start up, but only for a few seconds. I got my jeep in January so mine must have been built late 2011. Should we mention this to the dealer?

Chrysler has revised the heads twice on the Pentastar.The first letters on the head were AA then AB now they are AC. Anyone that has a build date before September 2012 can expect a head replacement sooner or later and there is no comformation yet that the latest revision has solved the issue. I know many people on the other forums I'm on have had their heads replaced twice and their are also some 2013's that are now in for a head replacement.

My 2012 runs well (build date Feb16, 2012) with 7600kms but I,m not kidding myself, I know at some point I'll be getting the head/s replaced. Sometimes the heads go right away and for some it can take over 40,000kms.

Chrysler definately dropped the ball on the design of this engine, probably rushed through the testing process to get the motor into production as quickly as they could otherwise the head problem should have been caught in pre-production.

i bought my jeep march 2012..my engine has ticked for months almost as long as i have owned my jeep i never realized there was an issue till i started looking up stuff that has gone to the shits with them. anyways my last oil change i brought it up and after the dealer took a look at it they said it was fine.. they also had no idea what i was talking about and had never heard of any engine issues.. any suggestions what i should do or if there is any dealer i could bring it to that knows whats up with them close to niagara?

Re: Valve Tick Issues
 

I hope this isnt an issue with 2013 models i already ordered mine

Re: Valve Tick Issues
 

Scott I dont know about your dealer, But mine in Brampton Would think a engine fire is normal..." its part of the breaking in process".<-----------Ive heard this 50 times now.

Re: Valve Tick Issues
 

i ve read some different things about the left head problems. A Mopar representative said that something like 16 000 heads were involved in a bad casting choice that led to a misfiring cylinder 2

Just hope he s right cause i have a 13 JKU:retard:
