should PCV hose off cause truck to die?
i pulled my PCV hose off of the valve itself today with the intent of doing a seafoam treatment. when i pulled off the hose, the truck sputtered and died within a few seconds. obviously, im causing a giant vacuum leak, so im not too suprised, but i've heard others saying to have the hose suck out the fluid from the can until it dies. i assume that this means that the truck should run without the hose on. should i be concerned about the condition of my truck? should i look for other vacuum leaks?

mine didn't die... it didn't run like normal but it didn't die.
I pored mine in slowly, not let it suck out of the can, that might be too much too fast. Can't say for sure.
But mine didn't die, it only died when i poured a huge ammount in raelly fast, it sputtered and stopped. Started back up and ran like crap. I then turned the engine off and it continued to run even worse, I guess sea foam ignites at low temps or something.

It could, that hose feeds into the intake so is like a big vacuum leak.
BTW, I find the vacuum hose that runs to the charcoal cannister is a good one to use for feeding Seafoam into the intake. Smaller dia. so it doesn't suck in too much product and it is way up at the throttle body so cleans more of the intake out.

For what it's worth, mine does the same thing and I also have a 22re. I usually pull the hose and then block it with my thumb so the motor won't die. I pour the seafoam into a cup and use my thumb to only let so much suck into the hose at a time. Once the cup is empty, remove my thumb and let the truck die. Reconnect the hose and let the truck sit for a while before starting back up and smoking out the neighborhood. Hope that helps.

Maybe you are already running too lean so the extra vac leak takes it over the edge and too lean to run. Just a guess anyway. My truck would run with a vac leak but it idled too high. BTW my air/fuel ratio with that vac leak was about 17, normal is 14.7 at idle.

Great idea, 4crawler. I read where one guy used a pair of vice grips on his brake booster line. He controlled the air flow by loosening or tightening the vice grip adjuster and fed the Seafoam (or water...I think that's what he actually used) through slowly.
My 22re will die if I pull the PCV hose, too. So, I used the break booster line. I think next time I will use the EVAP hose, though......with water. Much cheaper.
