Default PCV valve hose clamps

Yesterday I took my PCV valve out of my 2004 sti to clean it, but I couldn't get those spring-type clamps back on. These are the clamps that secure the hoses to the black plastic ports of the PCV valve assembly.

The hoses fit pretty securely by themselves around the ports without the clamps. I took it for a test drive and got on it a bit and it did not seem to cause any issues. When I got back I checked to see if the valve assembly had moved but it seemed to be secured in place. Anyone else out there running without those clamps in place? Any problems? Ie will the crankcase pressure ever be enough to push the valve off the hose?

If you really can't get them back on, i would at least pull the connections and spray some hairspray on the fittings... That should help hold them in place.

Those really are more a one time use clamp. Go get some cheap "worm" drive clamps (hose clamps) and secure it with that.

Great idea! Wish I had thought of that when it was all taken apart yesterday. Will try this tomorrow.

I considered that too. I think that's feasible for the upper hose, but on the lower one I don't think it's possible to get in there at a right angle to use the worm drive type.

No they are in fact NOT one time use. You can pop them loose with a smaller flat head screw driver. Use wire cutters/side cutters what ever you want to call them to reinstall them. Worm clamps dig into the hose and rip them all up, not only that but they are ugly. Id suggest reusing the factory clamps!

The oem clamps are the way to go for sure...........but......they are absolutely NOT intended to be reused. Yes you can finesse they off and on but new ones are just about a must is youre a first timer.

You kids are crazy, it reuse them every single day and not a single one has come back with a leak or issue.

Please explain why they are not reusable. Bring facts, not opinions.

Because they are one time install clamps.....simple as that. And this little kiddie is workin at the dealer which sells these clamps.Our procedure to remove them is to cut them off. I can also remove and install cv axle clamps....they are the same as our pcv clamps just bigger. You are not supposed to reuse them......you are supposed to cut them off with dikes.....not gently pry them apart with a micro screwdriver and gently pry them back together. I could reuse old piston rings too....no problem.......i mean, they go back on right? lol

Thanks for the commentary fellas. I ended up taking HinshawWRX's advice and buying some worm-drive clamps and positioned them strategically for maximum access to the screw head, for easy removal later. I found that I had to remove the throttle body to give me enough space to maneuver my hands in there, but that's not really a big deal....adds maybe 5 minutes to the job.

I think the OEM clamps could be re-used, but they are a bear to install! Not sure why they didn't just use the worm-drive type clamps here, like they do in most other places.

I'm wondering how they install those clamps in the first place. There must be a special type of pliers made specifically to squeeze them shut. Needle-nose, which is all I could fit down into that space (for the bottom clamp) just weren't cutting it.

When I was holding the clamps in my hand, they were simple to compress and latch. But once you have them squeezing down on something, they start fighting you and ultimately slip+spring out from your pliers.

Yes, I even made a video with my iphone which is being loaded to youtube right now. Showing it literally takes seconds to remove them and put them back on

+1 for re-using them.

Cuz those of us who do this daily......choose to do it the right way. Subaru says remove,discard,and install new clamp every time its referenced in the manual. They do this for a reason.......come to think about it....they also say the same thing about headgaskets.....radiator squeeze clamps......your oil filter etc.....Just because you CAN get it back on..............do you really want to? Ive never had one come back leaking either
But i always replace em cuz thats our dealership procedure.
End.

Oh boy..... Yep OP must be doing his own Warranty work. In that case OP you better go buy the OEM clamps.

Seriously dude, you are blowing the reuse of a clamp WAY out of proportion! Were not talking about a vital sealing gasket. That is completely different and you know that.

Thanks for the vid man. I kept trying to use needle-nosed pliers to do just that. Wish I had though of using wire cutters. Although, the bottom clamp (holds the pcv valve body to the tube coming from the engine) is pretty hard to get to, without removing a bunch of stuff around it.

For that section, since clearance is tight and it's so hard to get to, 90 degree bent needle nose pliers make it easy to secure the clamp. It's the same concept as with dykes or side cutters but you place the tips right in the center and squeeze. There's a step on the other side to grab onto, and the part that comes over has a gap in the center to clear the needle nose tip. It might not make sense reading it, but if you look at the clamp it'll make sense.

Yep I hear ya. Using the straight pliers I kept getting the clamp just to the point where it was about to catch, but then I think the pliers would interfere with the clasp itself and cause the clamp to slip out and spring back open.
