I was always under the impression that you need to replace the plugs when doing a seafoam through the vac line on the intake manifold? Plugs dont get gummed up?

 

Give your car to me, and then (depending on what you look like) I'll give it to you prison-style. :paranoid: Honestly, keep your car.

 

Tis true ..... I had no real reason to pull my intake other than for piece of mind. People get nervous about the dreaded build up...... when in reality..... I havent seen to many that have had a engine problem as result of valve gunk.


Maybe when more of these cars are up in the 120K range we will know more.
