How to: Clean your engine with seafoam!

Put about 1/3 can in a full tank (10 Gallons!) on my Datsun today.
I may be hallucinating but I am already getting better mileage and the idle is a bit more smooth.
 
So my car is still smoking badly. wtf? Smells real bad too. It's not just a little smoke, I'm mean the whole street looks like I did a huge burnout. Now I'm getting worried. How can I check to see if there is a real problem or not?
 
did you change your oil after you seafoamed it sk8er? I think I'm going to give this a shot very soon because I've got a rough idling issue right now and I need to clean my EGR valve also.
 
yea..I changed it right after. Last night I pulled my dipstick to look at the oil, and it seems really thin...almost water like. Surprising, the idle is better. lol
 
I've done something sort of like this with vehicles I've owned in the past. I put the seafoam in the PCV valve to get sucked right into the injectors. I pour the seafoam in fast enough so that as soon as I'm about 1/2 bottle the engine dies. Let it sit for 5-10 minutes allowing that seafoam to soak and then start up your car. Never had a CEL (non turbo'd cars). The remaining 1/2 bottle goes strait in the gas tank. Only smokes for a couple blocks down the street before it burns off. This might be easier for some people? Depending on what they want to clean I guess...

Did you put seafoam in the oil too? seafoam breaks down oil.
 
Is this the brake booster line? I need to make sure so I don't f it up...

dont worry if the car is kinda starting up for the first time... its nomral... Whatever you do make sure you hooked up the brake line back up before you go for a drive.
 
could someone post a pic of the pcv line, i am new to actually working on cars and of course chilton's doesnt make a manual for our cars much less any protege after 2000. I am going to seafom and was told since i have the msp to use the pcv line instead of the brake booster line.
 
I did mine off the brake booster line. The car could barely idle with it off. It made a huge difference on idle and the powerband. The brakes felt a little spongy for the first minute or so after reconnecting the line. I suggest two people do it, so one can modulate throttle, around 1500-2000rpm to get smooth coverage while the other uses the hose to suck up the seafoam. After that I shut the car off for 5 minutes, then fired it up and got no smoke at first, then I goosed the throttle to smoke out the neighbors, so I went for a little drive away from the house lol.

We did this about six months ago, and actually used this write up because I couldn't find a better location closest to the TB that would allow the seafoam to hit all four cylinders evenly. I basically wanted to see if others used the brake booster line like I wanted to. Only took like 6 months for me to actually join the bopard and start posting haha.
 
. I put the seafoam in the PCV valve to get sucked right into the injectors. ...
Ummm...What?
In no way will running Seafoam or anyting else for that matter into your PCV line run ANYTHING through your injectors.
Period.
The only way to run something through the injectors is through the Fuel tank or lines to the Injectors.
Did you put seafoam in the oil too? seafoam breaks down oil.
No..It does NOT break down the oil.

If you read the can it is safe to run in your engine oil and is used to help clean out the depsoits and sludge in the engine that you could not otherwise get to.

I am running Seafoam in My work truck right now due to a sticky lifter and The Shop that does our Fleet work is who put it in there.
I would say they know what they are doing...Considering its their "Business" and not ours.

This is Just some FYI and to correct some flawed and incorrect statements.

^People are just a little slow around these parts I guess lol. I'll be doing my oil when I get home, along with installing new Tokico HB struts, Progress springs, and AWR side MM inserts. I can't wait to get home and mess around with my ride:)

I am sorry I frustrated you. Clearly I was wrong and I apologize...I was relaying what I was told by the Car-x guys when I told them my engine was running rough (1994 Jeep Grand Choroke). That was a quick fix they told me that would clean my injectors. After some research, yes, the PCV releases the blow-by gases back through the intake manifold. This part is after the injectors, and is cleaning a different part of the engine, assuming you pour some sort of cleansing agent through it. The second half of the bottle though, does go into my gas tank and therefore, like you said, will be run through the injectors and cleaning them. Its a way of cleaning both sides of your engine, if you want to look at it as fuel going in, and exhaust and fuel vapor "re-burned". Either way, there was a lot of carbon that was burned out of my engine and I was happy about it, lots of dark gray smoke. The two cars I have done this to seemed to idle smoother after I did this, so I will do it again in my future cars. Thank you for the correction.(2thumbs)
 
What about using the vacuum line from the intake to the valve cover? that way itll go through the turbo cause mine has carbon build up in it. that safe?
