Brake Booster PCV

[tahoetoledo]

I'm looking for the PCV Vacuum hose on the Brake Booster where I would pour the SeaFoam in a 2003 Tahoe. Anyone have a pic???

take your engine shield off, u'll see a hose plugged into the engine all the way in the corner above the last spark plug on the drivers side. take the hose out make sure u take the pcv valve out because i dont want seafoam in it. i'll try to find u a pic and post it later. but under your hood right above the grill there should be a small drawing that tells u where the pcv valve is.

Follow that line in the second pic to the fire wall and pull it off there and dump it in. really easy. I didnt do it for a wihle cause I didnt want to mess it up, you wont! i will try and get a pic tomorrow.

Shit if you have a steady hand just poor it at the hole and the suction should help out with spilling. Thats what I did and it worked good.

Just did the SeaFoam treatment today. 1/2 a can in the gas tank, the other 1/2 through the Brake Booster Vacuum line. Cleaned the Throttle Body too and man, what a difference. Lots of smoke too. But it was worth pissing off the neighbors (one specific neighbor). Thanks for your help guys! I really feel good about it, plus I saved about 80.00 USD taking it to the shop!

anytime bud. glad everything worked out for you. repeat the same procedure in a month or so to get whatever is left out.

Be careful, not all these vehicles have brake booster vacuum lines. If you have the hydro-boost setup, that line goes to the power steering pump. Basically just follow the line before you pour anything into it.

its very good to sea foam the truck. it wont damage as long as you follow instructions and do it right.
