How do you Seafoam the V6?

So i have sea foamed every car i have owned. I even sea foamed our 02 TL via the booster hose and all went fine. But i did it to the accord and oh boy....... I did it the exact way i did the TL and every other car i have owned over the years but this time it didn't take well. Is it another hose i'm supposed to let it suck up the fluid through? When i started the car it idled really low miss firing which i expect that from the treatment. But it smelt like pure gas like the gas from your water heater or something that can explode. It smelt that way for a hour.... It wouldn't rev at all..... And the strangest thing of all........ It NEVER SMOKED!! No smoke NO WHERE!!! I let the car idle for 30 minutes before i even drove it and when i went to drive it it was jerky as ever and it did run but stunk and No smoke EVER came out the back. Eventually the car went back to normal operations but it kind of scared me. Has anyone had this issue? Or is the j30 such a clean running engine it is just no build up? I mean our 02 TL Smoked like nobody's business for a whole freaking day no lie.

I seafoamed all my cars, and alot of smoke came out. Afterward they all started burning oil.

I seafoamed my Accord V6 and no smoke came out, and it doesnt burn oil. Im guessing the V6 was very clean still.

Personally, i would never seafoam again. If you want to clean your engine from the inside out, use some Marvel Mystery Oil in the sump a few hundred miles before an oil change. Or you can check out a more effective, safer, and more expensive AutoRX treatment.

Dont go over mileage on oil changes and everything will be a-ok

Don't use that stuff on any engine with close-coupled catalytic converters (CCCC). However, fuel additives are probably okay.

Use a good detergent gas, and change the oil regularly, and you shouldn't need any treatments or additives.

How do you Seafoam the V6?

I think I mess my engine up with sea-foam, months ago I did the sea-foam after installing a ZDX Tb and Pnp manifold, I putted the sea foam on the gas tank, oil and a manifold hose. I follow a video of a guy doing it to his 3G TL. A couple of day after I started experiencing miss firing at idle. I have removed all of my mods trying to solve this problem with not luck. The last thing that is going through my head is that I had mess up the engine with sea foam.

Yea, I bought new ones, change my coils and did a valve adjustment, and removed every mod I had but the Air intake and exhaust. The weird thing is that the car run fine to me, and the miss firing doesn't happens all the time. Something's he miss firing is stronger then other and if I let it idle for 5 minutes or more when the car is hot it my check engine start to blink and gives me a code of all cylinder misfiring

Fuel injector cleaner, an ounce or two per fill, is the only thing you should ever put in your tank besides gas. I would NEVER put anything into the intake to clean anything. If it needs to be cleaned, the intake ports/throttle body, take it off the car to do it.

Did the seafoam in the crankcase clean some varnish/build-up off the front crank oil seal and cause it to leak? Your crank sensor might be causing the problem.

You changed the coils? Have you tried unplugging one coil at a time, while the engine is running bad, to see if the engine changes? Checked the wire harness connections to the coils?

i've never understood why someone would pour seafoam in with your engine oil. that stuff will thin your oil out. very bad.

What hose did you use to suck seafoam into the car? I've done it twice and both times there is very little smoke. Compared to my old 98 V6, the 7th gen V6 engine runs very clean. The old 98 smoked up like crazy. The first time I did it, I used the vacuum line behind the intake manifold -> almost no smoke, just a little bit. The second time I did it, I used the vacuum line on top of the intake manifold close to the throttle body -> smoke came out the next day when I started the car, it took a long time for fluid to creep deep in. Both times I have no issues, I have 155k miles on the car. You probably used too much, that's my guess. I had no more than half a cup in a small plastic cup.

I used the Brake Booster hose that runs to the manifold. The same hose i use on our 02 TL. I also just used less than half a cup.

And pouring in the oil is meant to be done before a oil change. Similar to that engine flush stuff you pour in the oil to break up gunk and stuff that you have to change the oil afterwards. Seafoam in the oil stopped my old V6 eclipse lifters from ticking no lie.

I've never used the brake booster vacuum hose, even though that's what seafoam recommends. I use the vacuum hose behind the intake manifold, the one used for the engine stabilization, whatever it's called. The one on top of the throttle body is safe also. But honestly, I don't think we need to seafoam the 7th gen, it has been so clean the 2 times I did it.
