i used seafoam at 100k and it didn't smoke up as much as i thought it would. i probably wouldn't do it unless at high mileage.

When it comes to products like this, I'm a big believer of the old axiom "If it ain't broke, don't fix it." While this may not do any harm, if you aren't having any issues that you think may be related to a dirty injector system or whatever, I'd be pretty reluctant to dump this stuff in the car just for the hell of it. I know many claim great improvement, but if your car is running well, I'd avoid these off-the-shelf, miracle cleaners. My 2, I'm sure others will disagree.

I poured oil into the crackcase, sprayed the deep creep down the intake tube, and ran it through the gas and then drove 300 miles with it and then changed the oil. Worked fine for me...

Most of people I know poured it into the oil. Even in the attached link. But if your car running great, why mess with it. I have heard many people having problems after seafoaming their car.

Did the seafoam at 60k. Vacuum hose, sprayed the intake put the rest in the gas tank. Not in the oil/crankcase. Big smoke, CEL came on prior to my taking it on the highway and blowing it out. By the time I got home the light was off and the car idled so smooth I wasnt sure it was running. Changed oil a week later. Havent changed plugs yet.

Now have 70k miles. Some deterioration in idle, throttle response, but I do need to change plugs, fuel filter and Im going to do the Seafoam again 2 days prior to the plugs, filter change. And change oil of course.

custom. ive done it on my gf's car and put it in the oil. no issues.
i have also heard the 1/3 1/3 1/3 directions too.

i have not seen a DIy that says 1/2 intake 1/2 gas, i really dont know who started that

it sounds like you have a coolant leak issue, and i dont think the seafoam caused it, just made it more pronounced and you found out about it. you are the first person ive heard of to have issues atfer using it.

Question for you:
Are boobs and hands polarly charged, thus causing the inevitable joining of the two? If so are some breasts simply charged backwards?

On a scale from 0 to 24...wait, 3 to 24, where 6 is the lowest and 12 is the highest, how freaking high re you right now?

She's got you high, and you don't even know yet.

I did the 1/3 method after following the website instruction. Car had 105k miles and it didn't smoke that much. After all that, the car ran so smooth that you could barel hear it from the outside apart from the fans. After 2 weeks it went back to normal.

So obviously, I think the seafoam did something but the effects aren't that long lasting.

True dat on the effects not lasting long. I wonder if the LubroMolly product might work better at actual sludge removal?

I think there's an awful lot of exaggerated expectation of what these kinds of products can do. Certainly in some cases they'll help, but more often than not I suspect the problems they seem to cause far outweigh any advantages.

Doing this on the weekend....I suspect my car will smoke like crazy since the engine is filled with sludge.

Mine smoked enough to get a few neighbors out of their houses..... CEL light came on and that freaked me out some but if you go blow it out at fairly high speed for a few miles it went off for me and the car improved in throttle response, idle, over all lots.

Didnt put any in crank/oil.

Im going to do it again.

Seafoam, 1/3-1/2 down the vacuum hose, 1/2 - 2/3 in the gas tank. Smoke it out at 4500rpm. WOT as tolerated and perhaps indicated by engine response.
Deep Creep the intake hose. Half a can, drive the car at this point. Spray other half can down the intake hose.
MAF cleaner
Replace air filter
Check out intake boots and probably replace
Perhaps clean idle control valve (Thinking probably)
Adjuster cleaned out, if Im doing the ICV
Drive 50 miles
Change oil and spark plugs and Fuel Filter once all seems well. Which it ought to.

I recently replaced the entire cooling system, air filter, fluids (xcept ATF).
