You've been doing it wrong. Seafoam injection port

[A.Wilson013]

Ok so am new and this could be dumb but here it goes, what thinking about using it in V8? Where should put it? It's my first Toyota alway had chevy lol love my 4R won't go back

Your PCV valve should be located on the drivers side of your engine, where you would add oil. If I were you, I would disconnect the hose from your PCV, and run it in from that hose.

Hmm, I didn't even think about this. I did my Seafoam treatment a few weeks back and just pulled the vacuum line for my boost gauge off of the drivers side of my supercharger. I think that the line fed in above the blowers rotors (which should have evenly distributed and atomized the treatment), but I will have to check tomorrow. COB, if I decide to run it through again to get all cylinders, will running the treatment through twice in such a short period hurt anything??

Also, a word of advice for those who are looking to try this stuff: When you go to suck it up through the vacuum line, don't completely submerge the line in the liquid (I did this and it caused my motor to stall out. It fired back up after cranking it over for about 30 seconds and didn't seem to do any damage, but boy did it freak me out for a few seconds). I found that the best thing to do was to pour the 1/3 (about 5-6 fl oz.) into a measuring cup or something similar, tilt the cup on an angle and, holding the vacuum line agains the side of the cup, lower it down until it is just barely touching the liquid. That way it is ingesting both the liquid and fresh air. You will be notice the engine starting to bog and you can adjust your method accordingly. :bluejump:

Ressurrecting this thread as Im doing the seafoam treatment through the PVC hose today. And I have a question, though from what I read I believe the answer to my question is yes. Can I pour some of it right into the oil fill lid? Reason Im asking is because I see alot of carbon on the valves right under the cap. Thanks in advance

Yes you can. But change the oil soon after.

Just FYI Seafoam is available in an aerosol version as well. It comes with a long spray tube that you can insert right in front of the TB, assuring good distribution to all cylinders and probably helping to keep the TB clean as well. It's a little pricier, but easier to use IMO.

How much should I put in? Say half a bottle?

I didnt know that. Good info. I didnt see it at autozone though. Where do you get it?

Got it at O'Reilly's. Basically you just pull the intake boot off the TB, position the spray tube right in front of the butterfly, then slip the boot back on over the tube. Start it up, wedge the throttle open a bit, and start spraying. I did short 5 sec bursts and let the idle come back up in between. Used about 1/2 a can as recommended. Super easy!

Read the bottle, it gives instructions on how much to put where (intake, crankcase, etc). You can put a little in and run for the life of the oil, or put more in and only run it 100 miles or so. I usually put it in a day before I do my oil change, but I drive 85miles a day. I bet more soak time would be even better.

Hmm . . . I guess looking on the bottle is a good idea : And it says you can actually run the seafoam for the life of the oil. I put in half the bottle. I plan to drive it for a week, then run the rest in through the pvc valve, and then change the oil afterward.

For those of you with lots of motorized stuff; Seafoam is available in gallon-sized containers for a very reasonable price (around $60). It works great in carburetor-equipped motors, too.

Ya I may run some through my suzuki sv650 in the future as I neglected to change the oil for several thousand miles last summer

OK, I know this thread's been dead a while, but I've been thinking about how I'm going to seafoam my Runner, and I've only seen mention of what I'm going to ask once...

Wouldn't it be even better to use the evap vac line to "inject" the seafoam? Using the evap line would expose the MAF AND the entire throttle body to seafoam, cleaning them as well. The PCV line won't do that. Plus, it will definitely be distributed evenly to ALL cylinders.

What do you all think?

 

[Singtoe]

There is no vacuum at that port. Need to use the pvc port.

Seafoamed the 99 today and little to no smoke came out.

 

[Benski]

I did both lines.

Yesterday I put a third in the brake booster, a third in the oil, and a third in the tank. Last night I read about the other line on the throttle body. Today I got another can and put a third in that line and the rest in the tank. Definite better idleing and throttle response and I like the smoke. I look like Cheech and Chong going down the road!

I know this thread has been dead a while but I was hoping someone might have some advice. I see that Seafoam has both a liquid and spray can. Is it worth to both? Pour some in w/ the oil, pcv line, and fuel tank while and also running the spray thru the throttle?

Does this make sense or am I spending more money to clean the same part twice?

Putting it in the oil is useless if your oil system is clean. It's better to slowly clean the sludge with good synthetic than it is to quickly dislodge it with harsh additives.

What's the point of putting the seafoam through the PCV hose when you already put the spray version through the intake?

1st off Seafoam is not a harsh additive. 2nd off: I was merely asking the question because when in the store, I saw that Seafoam has both a liquid and spray version. Didn't know if you were supposed to pour the liquid into the oil tank and gas tank while using the spray version for the intake or PCV hose. 3rd: I guess mistyped when rushing through the store as I meant you pour Seafoam in through the intake using either the brake booster line or the PCV hose. Since I bought this truck at the time from a previous owner with just under 200,000 miles on it, I figured it would make sense to give it a good cleaning because who knows how often the oil was changed.

I ended up using the liquid form and was very satisfied with the results. I am looking forward to doing this again this spring.

Lastly, thanks for taking almost 2 years to respond????!!!!!!!:bravo:

I will be trying the liquid version this week. 215k miles from previous owner, and they didn't know what maintenance was other than oil. With that said, they also didn't do silly stuff to it or treat it poorly.

I manually cleaned the Throttle Body and MAS already. Going to input the seafoam as shown at the beginning of this guide, and change oil after 100 miles. I'll let you know if I notice anything.

I will also be changing fuel filter this weekend.

Loved the reply to the 2yr old post. I have it gave a warm and fuzzy.
