View Full Version : Check your check valves.

I was checking my airbox today, basic maintenance inspection and I noticed the little check valve thing next to it is cracked all over the place. Anyways, just wanted to get a part number for the thing so i can get it replaced. I might as well replace all the check valves while I am at it? There are two or three more on the intake side of the engine. Also what would happen if i just removed it and ran a tube straight across (where it intersects).

if your going through this - might as well replace all of them - there are about 3-4 in the system best place to get it is purems.com - but you have to pay tax so that changes thing a little. You might also want to replace everything in the PCV system - these things are made out of plastic and rubber - and with an engine bay and the cold and heat they go through most of these things become brittle and fall apart

or you can replace them as you inspect them - but rather just do an overhaul while your there

Thanks for the DIY writeup man, it makes sense. You're right, everything in there is brittle and cracking. I've already had that T-splitter crumble apart, I replaced that piece with a generic t-splitter from Autozone a while ago. Man gonna have to order some parts now. [eek]

I'm actually waiting on the parts from that write-up right now. The dealer had to order the check valves. The check valve mentioned in the OP is what spurred me to want to do the whole PCV system like in the writeup. On my car the check valve looks like it is just disintegrating or maybe it got too hot and melted some.

P.S. The dealer is not the best place to get these parts unless you know someone.

O'yeah I'm well aware of that, see that little ICM piece on the bottom of that picture above, that shit was four bills from the (stealer)dealer. [mad] I had to get my car going that day. [:(]

Anyhow, I checked around and ECS has all the parts, so i just ordered from there. [up]
