DIY - 1.8t Lower PCV Hose install
You are all familiar with it. It's the second crappiest hose setup on the 1.8's, coming in just behind the upper Y hose. Eurojet just came out with an *excellent* replacement that is well worth the time and effort to replace. I hate doing things twice (except my 2nd timing chain is coming on strong) so do this once and don't worry about it again. Here's how you do it. Click on the pics for a supersize version.
- new Lower PCV hose (EuroJet recommended!)
- new PCV valve (optional)
- Blade screwdriver or 8mm socket (for clamps)
Note: As always, I can't be held responsible if you break more hoses while doing this. Please be careful!
A treatiese on one time use clamps. They suck and they truly are one time use only. To get them off, insert a blade screwdriver in the opening and twist back and forth until you spread the clamp out a bit. Pull the lip down and out, and you can get the clamp off.
1. Examine the new lower PCV hose. Attach the aluminum coupler and tighten the hose clamp down. Put the other hose clamps on semi-tight, so they don't fall off.
2. Disconnect the lower PCV hose from the crankcase ventilation hose (affectionately called the "Upper Y Hose")
3. Disconnect the PCV valve from the lower PCV hose. The valve is under the intake manifold and hard to see. It should be connected to the top of the lower PCV hose.
4. Disconnect the lower engine block connector from the block. To do this, you will need to pull out the locking clip, and pull up on the connector. Remember there is an O-ring inside the chamber, so don't loose it or break it
4.b. You may find it helpful to unplug the white connector to give you some work room. No, I don't know what it does.
4.c. Stick your hands under the mass of wires and hoses like this to help you get access.
4.d. Finally removed!
5. Now realize that you broke the plastic lower engine block connector trying to remove it from the old lower PCV hose. Curse in disgust and liberally apply plastic epoxy to fix. Look at pretty burlesque girls while you wait for the epoxy to dry.
6. Insert the plastic lower engine connector into the new eurojet hose and tighten the hose clamp. You will need to angle the connector as shown to make the PCV valve line and the upper Y hose line up properly.
7. Work the lower hose into place and re-install the lower engine connector into the block. Don't forget about the O-ring and the locking clip.
8. Install the PCV valve into the upper T on the new lower PCV hose and tighten the hose clamp.
9. Snake the long end of the lower PCV hose however you like through the jungle of wires, but make sure you can connect it up to the upper Y hose as shown.
That's it! I'm not a 1.8t guy but I hope this helps out.
