so i have looked at EVERY seafoam post and can not find the answer i need!

if i ONLY do seafoam down the break booster line, will i need to change my oil? and is this even worth doing?

 

if you put seafoam down the booster line then it will get sucked back to the intake manifold and burned in the engine and out the exhaust, i dont see why you would have to change your oil because of that, i would change my oil just as regular matience not because of anything to do with the seafoam in the way you are using it. i know you can put it in the oil as a cleaner. so go for it.

 

i think i might this weekend! want to clean it out and get the best sound out of my new glass pack

 

The brake booster line is the same as pouring it down the throttle body. If you let the engine die off and allow the seafoam to loosen things up, you will need to change the oil afterwords. Just plan ahead and do the seafoam right before a regularly scheduled oil change.

 

it will smoke like crazy also so don't freak out when it starts smoking. I've used it in my oil before and ran it the lenth of the oil change and never had a problem. i usually put a quart of tranny fluid when i change my oil i also run that the life of the oil change.

 

i love using sea foam it seems to clean so much carbon build-up and yes it does smoke like crazy. I have heard that you should change your spark plugs after using sea foam but never heard anything about oil.

 

No you don't need to change your plugs, nor your oil, its like Nike, just do it, However if you do put some in the oil don't drive around on it long. no more than 200 miles. But don't take my word, I'm just a newbie.
