Just wanted to get the word spread around there is a serious issue with the Honda 3.5 V6 engine which can lead to serious damage to the cylinder head and possibly the entire engine.

I didn't learn of this until recently, when the spark plug in the #5 cylinder shot out of the head and destroyed the coil, and trashed the threads. I found a bunch of different people this has happened to, and all of the results aren't good.

These were orig. plugs on a Pilot that has seen required service at the Honda dealership.

 

I just checked mine and found one plug very loose. DON'T wait until the recommended service interval to check your plugs....do it much sooner and save yourself from blowing an engine.

 

Thanks, checked plugs in pilot and ridgeline, okay.

 

Thanks for the heads up!

 

i recommend my customers to check their plugs at 30k don't care about the service interval, The honda's with VCM need to be changed much much earlier than the service interval, i do mine at 60k on my accord hybrid
