when i disconect the pcv it dies ? why ?
I have never had this happen before any ideas why it would kill the motor ? oh it is a 22 re by the way. i was going to do the sea foam that is why i took it off. it should run ruff but not kill it

iamsuperbleeder

because you basically open up a large vacuum leak, letting a ton of unmetered air into the engine, and it messes up the air/fuel ratio so much that the engine cuts off

oil cap?

Joshua4507

I was just trying to find out any useful info i could. on every other car i have ever owned it would run like poop but keep running but normaly never stall the motor

xxxtreme22r

in theory it's not supposed to, you sure your pcv is working properly?

DROPT

pcv is brand new

I drove 120 miles up some huge hills after forgetting to put my oil cap on.

It was little down on power and got worse fuel mileage. I ended up loosing a 1/2 quart before i found oil all over the ground the next day cause it dripped down from the splatter.

I was 2 hours away from home so it scared the crap out of me, glad it was just that.

you lose vacuum on the intake, the valvetrain doesn't care, unless you have a chromed oil cap, then it'll run better, at least with the older 20r's

Hey Joshua, my 22re does the same thing. I've never owned a car that died when I pulled the hose off. It would obviously run horrible, but never die. I guess its normal. I've never got a straight answer from others here about it happening with theirs or not.

My last 22re did NOT die when I pulled the hose off. So I'm not sure what that means...

I have to plug the hose with my finger now while I get my can of sea foam in position.

xxxtreme22r

nice razed, didn't think about the difference between pulling with and without the pcv attached, but that's a pretty darn good point, and could be why people are getting mixed results pulling their PCV when running.

BajaRunner

I'm strictly talking about taking the hose off from the PCV so you can use the vacuum of the hose to suck in Seafoam. I personally understand completely that its causing a vacuum leak, and understand it will run like crap.

My concern is that every other car I've ever dealt with, pulling the hose off to use Seafoam NEVER killed the motor. Do all 22re's die when pulling the hose off or not? Either those 22re's that are dying have really good vacuum, or they have a vacuum leak somewhere else.
