Tech Article: VW 2.5L 5 Cylinder IE Billet Valve Cover Install

In this tech article, we will go through the steps of installing our Integrated Engineering billet valve covers for the 2.5L inline 5 cylinder engine. The factory plastic valve cover is, well ...plastic.  At Integrated Engineering we know we can do better, so give your bay a upgraded pretty look with this much improved quality billet  piece.  This Valve cover will also make it easy to run a catch can or vent your crankcase pressure atmospherically.

The new valve cover is simple to install, and only takes a few hand tools.  Install simplicity: 3/10 Click the photos for a larger view.

Step 1: For the first step, you will need to remove your coil packs and disconnect your wiring harness from the valve cover.

Step 2: In this step, you will need to remove the 11 T-30 Torx screws around the outside edge of the valve cover, and the 4 down the center between the coil packs.


Do not loose these bolts, or the rubber seals around them.


Step 3: Once the bolts are removed, you are free to pull the valve cover free from the motor.  You may have to tug hard, pull from the outside edges.


 Step 4: With the plastic valve cover removed, take a rag and clean the edges of the head of any oil or grime to ensure a proper seal.  Using a new valve cover gasket, carefully place it onto the IE billet valve cover and be sure  it seats in the groove all the way around.


Step 5: With the new gaskets installed, place the valve cover onto the head.  Be sure the VC gaskets lines up properly and does not  twist or fall off track. Now that the new VC and gasket are lined up, you can re-install the 15 Torx bolts back into place.  Install all finger tight first, then tighten to 10NM from the middle  two bolts, working outwards.


Step 6: Now your Valve Cover is in place, you can re-install your coil packs, and wiring harness location.


Step 7: Now you can sort your crank case breather system.  Our valve cover is pre-drilled for a -10AN fitting, this leaves you with options to continue recirculating pressure back to the intake OEM style, Re-route to a catch can, or vent to atmosphere.  We will cover the second two options.


Step 8: To vent atmospherically or route to a catch can you will need a -10AN O-Ring fitting to X of your choice.  For example, if you want to run stainless steel braided lines and a fitting you would need a -10AN O-ring male to -10AN male fitting, then a -10 female to stainless hose fitting.  If you were running a hose, you would again need a -10AN O-ring male to -10AN male fitting then to a -10AN female to push-lock hose fitting.  On our install we chose to vent to atmosphere, we will later plumb in a catch can, we will update this post when we do.


Step 9: With the proper fittings installed, you will now need to block off your route inlet.  Luckily this connection uses the same fitting as our FSI boost tap, so plugging this is as easy as removing the throttle body and placing the tap in place.  The boost tap will need a 1/8th inch NPT plug.

Removed Throttle Body: (you can see where the boost tap will be placed circled in red)


Step 10: With the throttle body removed, use the boost tap with the 1/8thNPT plug, supplied O-ring, and push Clip to install.


Step 11: Re-install the throttle body and intake hose, step back and admire your shiny new IE billet valve cover.

    Just forked over the bulk of my savings when the OEM plastic cracked. Sounded like a coach’s whistle about 6 inches from your ear. Plastic?!? Integrated PCV?!?

    Furious at this practice and looking to remove the replacment at some point, to avoid this experience again. Plastic in a heated area will eventually degrade and that’s what these things are doing.

    Like the idea of the Al replacement VC, but as I live in California, I need to see what I can do to maintain 100% emissions compliance. Next step is finding how to do that.
