Seafoam treatment

ok so ive checked everything on my car that I could and had 3 local shops check the rest.

as far as they (and I) can tell there is no reason my car shouldnt be purring like a kitten instead of bucking and shaking at idle.

Not sure if the one shop that checked the compression really even checked it but thats another story.

I was thinking about trying seafoam. Ive heard good things about it other than it can foul your plugs and possibly ruin your cat (as if a flashing check engine light isnt a sign that it is already getting ruined)

Only problem is if I use the brake booster line (or any place to get it into the intake) wont it pool up in the bottom of the intake manifold due to its design and make for a potential hydrolock condition?

As I see it anything other than air that enters the intake manifold will pool in the bottom of the intake since it slopes to the bottom under the throttle body. Then say at WOT or sharp left turn make its way into a cylinder all at once hydrolocking the engine.


Any opinions?

You don't need to poor it in that fast. Pour it in slow enough to change the idle but not fast enough to stall. Make sure the engine is hot, this will help the product flash and not pool up as well. When the can is about half gone dump it fast enough to stall the engine and let it sit (These direction are on the can as well) after a couple of minutes the product will flash.

This will probably not fix the problem you are having!

Even if it doesnt fix that the $10 is worth pissing a few neighbors off around here :rofl:

Be careful with that Sea Foam stuff!!! I've seen it clog a cat in no time at all!! It works VERY WELL for cleaning and removing deposits of carbon from everything in the combustion chamber and intake and cleaning the injectors!! VERY STRONG STUFF!! I'm not so sure your problem is from carbon build up or a plugged injector but it surely can't hurt to get the crap out of the engine, but use very little at first and have that throttle body open and the engine racing if you're injecting it directly into the intake itself. I personally, just put it in the tank and drive the vehicle. :)

i have used seafoam for years in the oil, fuel tank, and intake. even use it to store engines. have had no problems with it. even helps to pass emissions. it would help the engine more than hurt it. just follow directions on back of can.
