Sea Foam Idea ?'s Already searched

[AFSP1211]

So I was screwing around with my CAI yesterday since my truck's been running like POO and noticed my TB caked with oil. Stuck my fingers in it and when I pulled them out they were black with oil. I didn't pull the TB to check the inside of the intake but I figured it'd be pretty much the same. I was reading up on Sea Foaming my engine and read about people bending rods and I really don't want this to happen to me at this point in time. I've got a little over 140K miles on my truck and I've never done an internal clean of any type. My main concern is with the amount of buildup that's probably in my engine a large chunk of POOP will seperate from its current location and find it way to my cylider and jack something up.
I gathered from reading the sea foam posts that if done slowely, and in proper amounts, putting it through a vaccum line is safe, in regards to it pooling in one cylinder, but is this something I should do?????

Overfilling is what causes people the problems with it. Small amounts or you will hydrolock the motor (bent rods, etc). Small amounts, let it sit, start it up and watch the smoke show. GM topend cleaner I think works good too (maybe Nathan will jump in here).

There was a great write-up on how to do it, maybe on silveradoss.com? I can't remember and I haven't been there in a LONG time.

K, I'm gonna do it tonight or tomorrow. I'll get a vid of it too. It SHOULD be an awesome smoke session with it not being cleaned for 140k miles. I'm gonna take it to a parking lot so the neighbors don't call the Fire Dept. thinking it's my truck in flames.

That vid should be hilarious!

Ive used the sea foam when I first got my truck, It had about 150k on it and underneath the valve covers it looked terrible so I could only imagine how nasty the crankcase was. I did the process twice within a year and when I had did my swap the 4.3 was damn near spotless inside. Motor still is runnin to this day with over 200k on it in an 80s p/u.

I didnt think something could hydrolock with a flammable substance?

I have used it several times, give it half a can through the vacuum line and the other half in the gas tank. No problems, it helps clears the mosquitos

Only issue I have really heard is people using it in the oil and it breaking sludge loose causing leaks around gaskets and what not.

You could probably search here and find a couple who bent rods.

I use Tune-Up cleaner from work (ford) it's in an aerosol can, I just pull a vacuum line stick the straw in spray the whole can (while its running obviously) shut it down as soon as the cans empty. wait 5 or 6 minutes and go for a balls out run, cleans everything right out

You can hydralock a motor with gas...

Ive been debating doing this, maybe Ill give it a shot tomorrow.
