Took mine in yesterday,they said it was the fuel injection makeing the ticking sound... hmmmm
What? Since when does fuel of any sort have anything to do with lifters? A lifter tick is generally an lash adjustment issue with the rocker/arms or an internal failure of the lifter body or roller tip. If the valve is not seating properly because of "carbon" then you might have a tick too maybe.Try running a couple tanks of premium fuel through it. It could be just a piece of carbon caught in one of your lifters.
Yep. My 2012 has it too. Seems to happen after it has been driven, parked and then started about an hour later. It's kind of a loud rattle/knock and only lasts about 10 sec or so. Doesn't happen all the time but makes me cringe whenever it happens. Definetly not the same as the Injector or valve tick that we all hear. Mine is going into the dealer for a recall and to have like 6 other issues looked at. My guess is the answer will be " Cannot duplicate customer concern, operating to design intent". :doh:Does anyone else have an engine rattle on start up. Its not all the time, prob 1 in 10 start ups. Its only for about a second too. Can't tell if its an exhaust leak or something in the heads. Stock manifolds, factory recommended oil, engine has 6K miles and has done it since new. Any help would be appreciated.
