Ok ive used seafoam a dozen times ive always been told slow dont go to fast or it will HL your engine this is supposed to be the official video dam he just pours it in there. If this is the case Im doing it to sloww.

it won't Hydrolock your engine. it will stall your engine because seafoam is not combustible.

If your idle is higher, you can pour it in faster. Most people do it slow because they don't have someone to move the throttle open while you pour.

Revving while doing that will really help remove the big chunks of carbon, and doing it slowly will clean the rest.

I use the whole can through the intake. But sometimes i put 1.4 can in my fitch fuel catalyst so the injectors get a straight shot of seafoam. You can buy a big in line fuel filter and temporarily hook it up filled with seafoam and get the exact same result.

Sounds like I need to do it again and have a freing hold it at 2000 rpm and let her rip. I just did it yesterday

 

when you do it there should be no smoke out of the exhaust. the smoke is the seafoam burning off and not doing what you want it to do.

 

Really? Even when you put it into the brake booster? Mine smokes like crazy

 

The smoke happens after you let it sit. Not when you put it in. I try to let it sit overnight.

 

I had it smoke for a LONG time when i was pouring it in slowly then i started revving it. Upon revving it after 1/2 of a can was drizzled in slowly, it was smoking down the road.

If you are not getting much white smoke, then your truck is really clean.

I would try this WHEN YOU ARE DOING YOUR NEXT OIL CHANGE:
1. Pour 1.4 bottle down the intake
2. Let it sit for about 15 mins
3. Continue as directed.

i believe that if you let it sit overnight, it will evaporate and dry out. After 15 mins of soaking, it will not be evaporated and the carbon buildup will be ready for the rest of the can (air velocity) to help clean them. I did something different one time:
I put the seafoam in an all purpose industrial spray bottle on the "STREAM" setting and just put it down the throttle body. Cleaned the throttle body too and you know that you are doing it nice and slow.

The reason i say do it at the next oil change, is that pouring it down your intake will have it go past the pistons and into your oil. Seafoam changes the composition of your oil and makes it thinner. So you would want to do it when you are doing an oil change to get that thin oil out of there.

 

my truck only smoked when i poured it in real fast and at high throttle! i do try and keep my motor clean.
