Is seafoam good for lt1's
 

is seafoam good to clean out the motor...and what do you pour it in to... i have never used it before so i just wanted to know if it good or not thanks

I've used it in mine didn't make a difference I only run 91. it smoked a little and this was when I had about 105k on it. I did it in my 06 envoy with 45k and it smoked out my block when I took off.. We only run the cheap shell 86-87 lmao I only use 91 so I forgot what the other two octane's are

theirs a complete how to wrote up on here..just do a search..i need to do this to my daily pos saturn

i was reading to use mopar combustion cleaner instead..

Saw this one a long time ago on LT1engine.com:

Long-winded but explains what he's doing, in what order, and why. FWIW/YMMV

thanks for the help

one full can in the vaccum line from the booster to the manifold, on full can in the gas tank and one full can in the crank case no more than 100 miles away from an oil change. i do this about even 12k miles. before i rebuilt the motor i did it often and when i tore it down it looked brand new.

Seafoam is the devil. Dont use that shit.

Please explain. Not being a dick, just want to know what's bad about it.

i have a 94z28 i bought it with a blown engine, i found a replacement engine that had been sitting for a while..
after i got the replacement engine installed i seafoamed it, basicly didnt know what oil the previous engine owner used and i wanted to clean it somewhat internally before i put in synthetic.. i've used a pint of diesel fuel to do the same thing on older engines.

I have seafoamed lots of cars. And stopped doing so after a couple Ks after the cleaning. I have found it fouls plugs shortly after treatment and a lot of cars I have done have started having slightly irractic idles when cold started. I wont seafoam a car ever again. Except maybe run it through the gas tank.

everyone has heard of the "miracle" engine repair stories from seafoam, but I've never seen anything too amazing...chances are, if you're having engine problems, the solution to the problem usually doesn't come in a bottle...some of my buddys put it in their gas tanks over winter tho...

Understood. I'm a 'take it apart and clean it by hand' kind of guy. Hell, I pulled the seats out of my 03 Accord last week so I could vacuum properly :jest:

I still cant get past the name Sea foam for a car, so Ive never used it and never saw positive results from people who did.

Only reason to ever use sea foam is if there is a carbon knock in the engine or if the engine is suffering symptoms of carbon buildup.

That shouldn't be a problem with a properly tuned car as long as you go WOT often enough.

Right. It can be depending on how it's driven. If an individual drives like old people fuck, never taking it past a certain rpm, driving short distances or predominately in stop/go traffic then it can be a prollem.

Post up the pics of your steam cleaned pistons.

I pulled the valve covers on my car about a month ago for the first time since I bought it. A lot of gunk built up under there. I put the half-can of seafoam in the oil and drove it for 100 miles non-stop. Changed the oil and did find lots of little b-b sized chunks of sludge, but pulled the valve covers and couldn't tell much difference there. Car runs great before and after the sea foam, just using the stuff to see if it would clean out that sludge left by the previous owner. When I bought the car, the oil was like syrup when it drained out.

If you use quality oil the engine internals will remain spotless and sludge free for the engines life.
