at 10,000 miles. i say it looks normal.

Damn! I thought I didn't drive my car much. So how many miles do you have now?

Sorry to jump in, but never used or really of sea foam. Do you add it to your gas and it it safe for blower applications.

They claim it is safe for blower applications and safe to add some before the blower through a vacuum line, but do that very, very slowly and at your own risk. My opinion of adding it through a vacuum line is it doesn't go evenly into each cylinder, so don't do it. That's why I mentioned pouring the same amount into each spark plug hole with a hot engine.

It's really not different than sucking oil through the blower from the pcv line.

I thought you might just add it to your gas, Thanks..

You can add it to your gas, oil or through a vacuum line.

around 22,000 and she's still going strong!

I agree. It is unrealistic to think you could keep the piston tops free of carbon and one could do more harm than good trying.

There is no excessive carbon build up there.

Oh noes! Got some vertical scratches/marks in the dreaded #8 cylinder. Sorry the video is so long, i can't cut these with quicktime pro. Skip to 5 minutes, that's when I noticed the chip in the cylinder wall, then the marks. From a little google research, the vertical lines could be perfectly normal or it could be hurting compression. This is on the outboard/thrust side of the cylinder, so I'm guessing the piston skirt has rubbing. I have no oil consumption and the spark plug is stupid clean.

I scoped #6 as well, looking for vertical lines. You can see some faint ones. I might do #5 and 7 tomorrow. I noticed there is less carbon build up in 6.

If the car is running good. You just worrying yourself into finding something that really isnt there.
