I just have a quick question about Seafoaming the intake, from what I understand the only way to do it on the tC is through the brake booster line. I'm just trying to make sure what I think is the brake booster line is what I have in the pictures below. Please Let me know. Thank You

 

Why would you use this product? I mean it just looks so dangerous and the gains from it are not proven so do you want to spend money/risk ruining your car for this?

I know it doesn't answer your question at all but I really think it's a gimmick like most car care products out there.

First, do not use the break booster line, use the line that comes off the intake manifold. I've done the sea foam cleaning through there and it worked well. Just don't be surprised when your car runs like junk for 5 minutes.

 

Yea the seafoam is a great cleaning product, but like tcengel sayed your car will run crapy for a few minutes. You might as well do ur cylinders while your at it, jsut take out ur spark plugs and poor a little down each one. put your spark plugs back in ( with out hooking up the wires) and crank ur engine for a second then just let it sit for about 3-4 hours to work. When you do fire it back up dont be serprised if you see a big cloud of black smoke out the tail pipe thats a good thing. Take it for a drive down a hwy and get it nice and hot and youll be good to go. the stuff works wonders

 

I know you probably wouldnt tell me to do something that would seriously damage my car but.....that sounds terrifying....lol I was already scared of doing the Seafoam on the intake. I was scared of pouring too much in and effin up somethin, but your saying pour some in each cylinder and and let it sit for 3-4 HOURS???!?! That sounds dangerous as hell, but maybe I'll try it when I hit 200,000 miles, im at 147000 now so it wont be too long before that happens...

 

yea i know what you mean but it will brake the carbon lose thats why when you finaly start it up it will blow out a black cloud. Im also not saying to poor a lot down them. Im talking like just a table spoon or so each. it wont ruin your engine at all it will clean it up but you need to let it sit and soak to brake the stuff loose

 

If you have that many miles on your motor already I would skip the seafoam. It might do more harm than good.
