In this video, we are going to show you how to replace the PCV valve in this two thousand seven Audi A4. This one has the two point zero turbo engine in it. All you'll need for tools is the T25 Torx driver and a hooked pick.
Remove the engine cover.
Locate the PCV on the rear driver's side of the valve cover. Remove the upper hose on the PCV valve by pinching together the tabs, carefully working it off of its lines. Work the lower clamp off of the PCV valve. Just make sure it's disconnected, you don't really have enough room to set it off to the side in any way.
Remove the four T25 Torx screws with the T25 spit socket, or screwdriver. Where it's difficult to reach down and hold the last screw with your finger simply pull out on the housing as you unbolt it. Angle up the housing and make sure that the screw stays in there. Using a small pick, remove the old gasket from the slots on the side of the valve cover.
Install the new gasket into the valve cover. Be sure that it's fully seated, lined up properly. You don't want any slack in there, or any parts that aren't seated fully into the valve cover gasket where they could pinch, get locked in there crooked when we install the new PCV valve.
Bottom bolt here, next to that lower breather line, going to go ahead and rest that in there. Carefully lower the PCV valve housing back into place. Line it up and tighten it down.
Reinstall the remaining three screws. You may have to move this lower PCV line to get to the top right. Snap the lower breather line back into place.
Reinstall the upper PCV line until they snap into place.
Reinstall your engine cover.
Thanks for tuning in. We hope this video helped you out. Next time you need parts for your car, please visit 1AAuto.com. Also check out our other helpful how-to and diagnosis videos.
Why you Should Replace Not Restore Headlights
See why replacing your cloudy headlights with new ones is always better than refinishing them Why should you replace your headlights and not clean or refinish them? Three reasons: It's a simple fix, it increases visibility, and it enhances the overall look of your vehicle. Headlights are made from a polycarbonate plastic that can be damaged by UV rays from the sun or suffer pitting caused by road debris light salt and rocks. If you look closely at an old set of headlights, you'll see that the lens is full of micro-cracks. This is called crazing. This crazing, along with pinning, will turn your headlights from crystal clear to hazy yellow and it cuts the output in half, making it very difficult to see at night. It also makes your car look old and dated. With parts from 1AAuto.com and our how-to videos, you can make your vehicle look new and stay safe on the road.
