yes very slowly as soon as you hear it start to die then your going too fast, slow down and just let it suck it in slowly

no brake booster on a new edge

when i did it, i used a straw and fed it straight into the plenum. just disco the line that comes from the PCV

Use the vacuum line that goes into the back of the plenum. That worked for me...and i had a nice smoke show from this stuff. lol

i agree with this guy


several people on my local forum have either owned or worked on cars that seized up from putting it in the oil...one car made it 100 miles, 2 others spun rod bearings after a couple hundred miles, and one had the sludge get knocked loose and block the oil pickup screen and starved the motor of oil

if your car is in that nasty condition that it needs seafoam to clear the sludge out, then theres a good chance that sludge is part of the seals by now and you will either harm the engine or cause an oil leak....if you feel like you need to add something to you oil, which i think is way unnecessary, try marvel mystery oil...i used it in my old truck to quiet down the lifters, and its not going to harm anything


seafoam in the intake and gas is great though

ive used it in my lincoln mark 8 and my firebird with great results. i used it in the gas, intake and crankcase. i only ran my car for 50-75 miles with it in the crankcase, any longer and i felt uneasy about it. it helped out the idle on my mark 8 but did nothing for my firebird.

Ive used seafoam in my crankcase in every car I ever had. You supposed to change it within 24 hrs to be safe. Also poured 1/3 in the tank and 1/3 in the pcv valve which is connects to your plenum. Seafoam representitives even claim that it is supposed to make your car die so you dont want to pour to slow to keep it from dieing. Just do 1/3 in all three and change your oil the next day and it will be brand new. Makes my cars quiet everytime. If you do your research with seafoam you will understand why its out there to use and why it says it can be used for a lot of stuff it is not HARMFUL to use on your car. The stuff realy works just dont use it all the time and 10000 miles not really need it yet but once every year or so is fine.
