Ive been wondering this b/c Im about to do it. Ive heard about how you need oil change and new wires after doing it but is there anything else that needs to be done after the foaming?



If its already been asked just direct me to it the search isnt working for me.

I've heard it burns up valves.

Not true at all.

Seafoam is great stuff, cleans out the engine nicely. Its pure petroleum, so it burns cleanly and won't damage the engine. Really helps with fuel economy and smoothness of the engine.

I could always be wrong.

The huge cloud of smoke is pretty cool.

There has always been two sides on this topic. One who say it works great, another who says it will destroy your engine. I wish somebody could put this to rest with some proof or something along those lines. I am about to use it in my engine.

Seafoam works great... most of the people who have had bad experiences with seafoam screwing with their O2 sensors and plugs is a result of having never done seafoam before and throwing a can into the intake when the car has over 100k on it... Not saying seafoam is bad over 100k or anything, however, over all of those years, alot of carbon builds up inside the engine and seafoam lifts the carbon and shoots it out the exhaust..... so obviously your O2 sensors may go bad as a result of this carbon clogging up the sensors... iv never had seafoam foul my plugs or my friends plugs or wires or anything of the sort... only once did it clogg a buddy of mines O2 sensor.... If you do seafoam everytime you change your oil, you shouldnt have to worry about the sensors since the engine should already be pretty clean

is sea foam one of those engine additives you get from like riebies or auto zone or kragen?

yes, you can get it from pretty much any auto parts store. i know for a fact that discount auto parts does.

Hi Folks
True statement - I can personally state that is what happened to me. I had to replace the Driver side O2 sensors. It was throwing a P0420 code - bad CAT but it really was the O2. More than likely just the top one but I replaced both on the driver side. I can't blame SEAFORM because I had 117K on the O2 sensors, so they should have been replaced anyway. Improve the performance - runs better.

I have found exhaust leaks, and when you think of Speed density motors, any kinda leak can wreak havick on a engine tune/driveability.
SO, I like it and recommend it.

How do you guys put seafoam in your LT1? I've heard that if I just use the brake booster line It will just "flood" cylinders 3 and 5 and barely get the rest of them. Do you use more than one vacuum line? Please tell me as I've been wanting to run a can through my 94.

I was shown to put it in through my vaccuum line. It has never done me wrong. I think seafoam is great.

Is there a how too on this my 94z needs this treatment seriously!!

I treated my 1994 t/a with seafoam applying it through the vaccumm line that goes to the brake booster... works better if you use some sort of bypass valve releasing small amounts of seafoam untill the additive is finished, car might idle funny but that stuff works!!! It might damage spark plugs tip/electrode from the run with the additive... expect lots of smoke from the exhaust...

i just changed my oil, spark plugs, and wires, AND THEN used seafoam. is that bad?

I would have done it in reverse order of what you did.
