Seafoam?

I've never used it, but the website (from the link above) says you can use it in the crankcase.

I assume you changed the oil immediately after?

When Added to Crankcase (Oil)


Frees sticky lifters and rings
Increases R.P.M.'s vacuum and compression
Cleans dirty parts
Removes moisture
Cleans PCV valve systems

One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

So you're talking 7.5 OZ, not a whole can!!! If you go the wrong way using PCV, you're dumping in a lot more than 7.5 OZ.....
 
I just used a half a can through the brake booster vacuum and the smoke show was less then spectacular. I wacthed vids on Youtube and was all amped up about smkin out the neighborhood lol.

You have to make sure the engine is up to full temp. Then you put the stuff in and as the can empties you stall it out but taking in too much. Let site for 20 minutes or more. Then try to start it up, may take a little work. Then rev that engine really good - THAT is when the smoke really comes out!
 
Which way into the PCV valve! :) One way is into intake, other way is into crank case. You do not want to dump much of it into the crank case!

The PCV doesn't suck, it relieves crank case pressure, back into the intake manifold. If you hooked it to the PCV, it would more than likely blow crudy bubbles in the SeaFoam can, haha.

When you're sucking the SeaFoam in, MAKE SURE you rev up the engine, up/down up/down, and rev it high enough so that they IMRC's open (3250rpms). If you don't rev up the engine and suck the SeaFoam in fast, you'll be burning off a lot of it as the car idles and draws it in slower. When I do the treatment on my cars, it takes "maybe" 7 seconds to suck the entire car into the intake. I let it sit for about 20-30 minutes and the smoke show is outragious. The cars on my street almost stop in front of my house because they think somethings on fire. Anyways.....if you don't bring the RPMS high enough, the IMRC's won't even get the treatment because no airflow goes past them unless they're open.

Let me find my videos.....

Oh...here it is....

Lol, just kidding.

Here is a video of my Dad's 240SX with 260k miles on it getting a 1/2 treatment after I did a 1/2 can on my Mark.



Here is the video of my mark. (BTW...thats my custom Rev limiter...4k in P or N)



Here is a picture of the PCV valve and the little nipple on it I use to do the treatment everytime.

Man....going through my 27 pages of photobucket pictures/videos of the Shark makes me miss it. :(
 
Yeah....it really hit me when my best friend and I raced and I got to hear/watch it from the outside. Sounds freakn MEAN with the cutouts open and the stall converter. Oh well....
 
I ran the car a lil bit till the guage was up near the "A". I then sucked in a half can rvin the car up to 4k and down to 1500. Let it sit 10 minutes and then reved it again up to 4k down to 1500. After there was no smoke only about 45 seconds. I took it for a highway drive and still nothin. I will try again. I tried to find the vacuum line for the IMRC but i couldn't tell which one it is.
 
Intake Manifold Runner Control

They open and close depending on RPM and allow air to move from the long intake runner {long runner is torque for the low end) over to the Short intake runner {short runner for top end}

Below 3ish thousand RPM's you are on the long runner, above 3K your on the short runners as well.
