Honda Pilot Problem Report
Honda Pilot Check engine light due to sticking rocker pins
On some models sticking rocker pins in the valve train can cause a loud engine noise, and the Check Engine light (MIL) to come on. Replacing the rocker assemblies is required to repair this problem.
As the motor warms up the sound changes from a light tick to a knocking sound.The Honda dealer told me they occasionally have a Honda auto come in with this sound, don't worry about the sound, and to keep driving the car.When and if the sound gets worst they'll pull the motor apart to figure out the problem.This do nothing repair costed me 170.00 dollars,Thanks Honda!!! I would like to know what the proper repair would cost? Thanks, Mike R. - Mike R.
Ref: 2008 Honda Pilot I was on highway when I accelerated to pass. A severe hesitation occurred, a vibration began I assume from losing compression integrity in a cylinder due to the rocker pin malfunction and lost significant power and could not complete passing the slower vehicle. Fortunately this occurred on an interstate divided four lane instead of a two lane highway which could have put people in a dangerous situation. This may be something USDOT may need to be informed of. I have researched Honda service bulletins (TSB# 07-070 in particular) and they have been aware of this for a while. My 2008 Pilot is at a Honda dealership now being assessed. Judging from the rhetoric from the service writers I get the feeling this dealership is not going to be as accommodating as they should given the severity of this obvious factory flaw. They suggested an engine tear-down when most likely a VCM problem and maybe rocker arm assembly repair/replacement is all that is needed to resolve. My Pilot has been maliciously maintained, oil changes every 3K or every ninety operating days which is standard maintenance protocol for light and medium duty vehicles in most fleets. In my past employment I was a fleet manager for twelve years and have always applied that protocol to my own vehicles as well as Honda’s suggested factory service recommendations. I have always had a great respect for Honda reliability and Honda's founder. In my business I need a highly reliable vehicle. Needless to say with this happening at only 32K miles I am very disappointed and will be reviewing and reconsidering my future resource and asset needs. -GH- - G Hender
