PCV Check Valve

[AUSVX]

Hey all, as some of you have probably read in other posts of mine, it looks like my PCV check valve needs either cleaning or replacing. I was wondering if there's a how-to (i couldn't find one) or a walkthrough on how to stop my oil dipstick from popping up due to the pressure build up.
On a scale of 1 to 10... 10 being hardest, does anyone know how hard it is for someone like me to fix? (I don't have too much equipment and experience). If i were to see step by step pictures and instructions, I'd like give it a good shot.
Thanks, Jordan.

I would replace the o-ring on the dipstick as well. It is usually very brittle by now and when you push the dipstick down, it just slides in and doesn't snap. When you replace it, it will take more pressure to put it in, but it won't work it's way out either. Good luck.

yeah that's an awesome how to, thanks a lot. My last question before i rip into it. Is this part specific to any other Subarus? or just to the SVX... That way I'll know whether the part is already in Australia or not. If it's SVX specific then I obviously won't fix it today, because i might need a new check valve, but if other Subarus have the same part then that's be great

It's the same on every Subaru I've ever owned.

I think some of the newer (2005+) may be different???

Hey, I hate to sound dumb, but what's the functionality of the check valve?? and also, is the I.R.I.S valve a whole different ball game?

Hey dere. Where and what is this dipstick to which you refer with respect to the o-ring you mention? Thank you.

Check out my locker, I made a custom tool to remove the PCV valve. Try making one up, it really made the job easier for me.

I don't know what size pcv valve they use down under but 19 mm is a bit large here in the states. I think it's either 12 or 14mm.It's been awhile since I did mine so I forget exactly.I also just used an open end wrench but I guess a crowfoot would be a bit easier.Good luck

It's 19mm here too...

<trying to picture how you got an open end wrench in there???>

[dennyo]

I stand corrected.Like I said it's been awhile!After the cover comes off it's not to hard to get the the wrench on the valve.Took probably 15-20 minutes tops.My apologies for dispensing bad info.

Just so everyone knows that a 19mm is the same as a 3/4.
