I bought a can of sea foam yesterday cause i have heard really good things about it. So how exactly do i use it through the PCV system?

 

exactly what is says on the can. then your trucks gonna smoke when u get on it afterwards.

 

I usually put mine in through the brake booster vacuum line if that helps you. Just pour slowly then when you want to kill it to let it soak for 5-10 min pour a shitload until it dies out. Then wait 5-10 min. then drive around and get on it a couple of times until the smoke clears and you're done...Zed

 

can you use this sea foam on a 93 Silverado 350?

 

I would suggest changing your oil afterward. Just do it right before an oil change.

 

pour it through their very SLOWLY. it is possible for you to pour it through to fast and it puddle up in the cylinder and cause some problems due to way to much cylinder pressure. i worked at a national repair center chain and we had a guy who thought you could just pour the stuff through and it was a 4cyl but it ended up with 3 straight rods and one bent one. also, afix the throttle to hold at about 2000rpm while pouring it through SLOWLY.

 

I pour it into a cup then stick the hose to the top of the fluid and have it suck it up. If the engine starts to bog down, I pull out just a little so it doesn't suck too much, too fast.

Get the engine to operating temperature before you do the Seafoam, it will be more effective that way.

 

Thanks for the advice. I'll try it this weekend.

 

I wouldnt suggest 2 cans back to back. Seafoam washes down the cylinder.
