Seafoam question

[ellner357]

So i recently got my hands on a 99 4runner and I wanted to do a seafoam treatment on her. My issue is before purchase the O2 sensor was replaced. I know I'm risking the new sensor if I do. Is there a way I can do this and not kill my sensor? I know the site says it's O2 sensor safe but what I've read here I don't trust it. I'm curiousyour opinions and ideas.

Youre fine, go for it. Won't hurt it.

Buy the Seafoam Spray, works great. Will do 2 vehicles also.

I originally bought the spray. It sucked. I returned it and got the liquid, which IMO, worked much better.

I used a method found on Yotatech and hasn't cause any problems yet. I thought I f*ed up when it was taking for ever to turn over I was praying for it to start! I sucked everything thru the PCV because I didn't know what line to use. So I used Google and found two video's on YouTube. The first one tells you to use the brake booster line and the second gives you a reason not to use it. Not sure who is right.

Seafoam, Marvel Mystery oil, Methanol injection, they really work! - Page 3 - YotaTech Forums

I thought the same thing about seafoam and still have some questions about it clogging o2 sensors and cats

Use the PCV line.

the brake booster line feeds it into one cylinder.

The PCV line feeds it into all cylinders. Not to mention, it also cleans the PCV out.

It works better that way.

I've seen the how too videos thanks for the links. Could i potentially pull the O2 sensor and run without for the treatment? My concern isn't the how too it's the saftey of my sensor.
