Hey there, i have some questions regarding SeaFoam.

I have an 01 Odyssey with 150k miles on it. It just turned 150k last week. I have some questions about using seafoam to clean up the carbon buildup.

1. What is the best method to do it? Is the brake booster in the Odyssey a good vacuum line to use?

2. It has 150k on it...is that to old to use seafoam? could i possibly damage my engine beyond repair due to its age? It has been very intensely maintained all of its life, oil changes every 3k miles, every scheduled maintenance.

#. Around the same time i do seafoam, i plan on changing my spark plugs to NGK IK iridiums. Should i change the plugs before or after the seafoam treatment?

4. Do i need to perform an oil change afterward?

Any help would be greatly appreciated.

 

Yup. Just follow the directions on the back of the can.
Sea Foam does great at cleaning the crud out. Don't forget to add some to teh gas tank and oil.
Change the plugs after. If there is buildup in the chambers you could foul the plugs.
When it's added to the oil, the directions state to change when the oil becomes dirty.

Just follow the instructions on the can.
