HELP adding seafoam to 2.7l pcv valve

eric1bss · 11-29-2005, 06:22 PM

I've been searching for a while now, and I haven't yet read the proper way to add sea foam to my 2001 tacoma 2.7l pcv valve. I removed the valve and attempted to pour the seafoam in the hole where the valve was, but it just got blasted out at me because of the air flowing out of the hole. Could someone PLEASE tell/show me how to add this magical seafoam to my engine!?

You are supposed to pour it into the hose that was attached to the valve.

If the hose is off the engine stalls out. I could leave the pcv valve in the hose and try and pour it through the valve, I guess? Is this correct?

WAIT before you hydrolock it.

pull the hose off, and squeeze it about half shut. it'll seem like its about to stall out, but just squeeze it some to keep it running. SLOWLY pour the seafoam into the hose, it will suck it in. don't pour it too fast, you want the 'suction' to aspirate the liquid. and if it stalls, don't keep pouring.

I honestly don't know. Try and pinch the hose a little when it's off, use a tool to help you if you need it. It should help the stalling. Did you try the brake booster vaccuum hose too?

Didn't try the brake booster vaccum hose. Don't know exactly where it is. Can you tell I'm a noob when it comes to engines?

just use the pcv and squeeze it with your hand if it sounds like its going to stall

The BB hose is the only one going to the big black round thing in the driver side rear of your engine compartment. But the safest bet would be to go through the PCV host, pinching it during the process. As long as you go slow and take your time, you'll be fine.

I used the smallest hose I could find on my 22RE. Let the vacuum suck the Seafoam into the intake and I controlled the rate by dipping the end of the hose in and out of the liquid. I used the vacuum line that runs to the charcoal cannister and attaches to the throttle body on mine. Worked fine.
