The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.Google+

ticking noise from front of the engine. Two diagnosis the dealer says removed front valve cover and rocker arm shaft, shaft shows some wear. oil has heavy metalic tint probed around cylinder head with magnet, found small pieces of metal that looked like bearing material. they charged me 240 dollars and told me I need to replace the engine to the tune of 7000.00 dollars. Second opinion said I need to replace the rocker arm pedastals. 2 hrs labor and 200 dollars in parts. I haven't done anything yet what would you do?
My Pacifica engine just started clacking as if it were gonna blow! A repair center said the rocker arms are going bad and gave me an estimate of $1500 to fix. They said they'd just keep driving it as it is. People stare when I pull into a gas station. Its that loud! I'm so upset because I loved this car until now. The trade in value for it should be $6000 however a dealer said they'd only give me $2500 for it because of how it sounds. Now I'm stuck with it!

The ticking sound I had developed into a...almost grinding one. Gas millage went down allot and my oil seems to need filling quite often.

tgicking started about a week before Christmas 2010. By the time the we got it to the dealer, it was knocking like a diesel and the fuel economy fell to around 11mpg. Dealer says rocker assy and it's gonna runs just shy of $600. Extended Warranty Co says all parts are covers but they are trying to say I failed to maintain the vehicle. We got it with 39K on it and since that time I've changed the oil EVERY 3000 mi just like the reminder tells me to. Dealership say that it is common in these engines and there is nothing I could have doen to cause this. If only I had known....I'd went with the 4.0L. Love the car though...just not the engine.

Engine has had a small tick at start up and slowly got worse. Suddenly it let loose completely and started ticking loudly. Took apart the rear rocker assembly and noticed the exhaust rocker shaft could spin so I replaced the rocker arm pedestals and shaft for around $80.
