How to: Clean your engine with seafoam!

i attempted the seafoam treatment on my msp today, it really helped my rough idle a lot. runs smoother now.
 
ok i just did the seafoam smoke went away now my question is how long do i leave the seafoam on the crankcase? should i change the oil now?
 
i understand that seafoam breaks oil down. you will want to change it within a day or two of driving.
 
i went out for a long drive and came back to the garage i got my oil changed now it feels kinda different now than before
i just put 4qt of 10w40 mobile 1 synthetic, mobile 1 filter and a engine restore additive is that ok?

I ran seafoam through the p5 tonight. In the past I had run it though the cruise control line but for some reason I decided to put it through the PCV vacuum line. I couldn't see it too well because it was dark but not I'm unsure whether the PCV line runs to all cylinders or just to #1 and #4. Does anyone know for sure? Any pictures of the PCV vacuum inlet from inside the intake manifold? If it only went to #1 and #4 I'm gonna have to buy another can of it. Also it did not smoke very much, only a little bit for the first 10 seconds or so.
 
performed this today for the second time ever (last time was maybe 50K ago) and the idle is SO much better. feels like a new car and made me appreciate the twiggy cams more.

going to change oil tomm.
 
Yeah I just did mine yesterday. Gave it the royal treatment. Did deadpan through brake booster, then added some to oil then went for a drive I was getting crazy looks .. Then put a qt through before adding oil pan bolt. Added some engine restore (smurf jizz) it's blue.. Lol also added fuel restore to gas tank . Car runs 100 percent better can barely hear it's on . Stuff really helps out noisy litters in these cars.
 
Use Marvel Mystery Oil. I believe it works just as good as seafoam and is less expensive.
I've been using it long before seafoam came around.
 
It can a far as carbon deposits are concerned. If you have a faulty sensor it won't fix that. I'm not quite sure what you are asking about the tps though.
