VIDEO: B8 Audi S4 3.0T PCV Replacement DIY from FCP Euro

Anyone that’s had any sort of older German car knows that PCV (Positive Crankcase Ventilation) valve replacement can be a massive headache. While not catastrophic in its failure, a faulty PCV valve can cause a car to consume heavy amounts of oil, create vacuum leaks for the engine and cause it to run lean. They need to be replaced every so often and parts aren’t typically too expensive. However, replacement is usually quite labor intensive, which makes it an expensive job to do. Thankfully for B8 Audi S4 owners, FCP Euro has a lengthy and comprehensive DIY video.

 

In this video, FCP Euro gives you the entire rundown on the replacement of the PCV valve for the B8 Audi S4, S5 and pretty much any other Audi that uses a 3.0T supercharged V6 (it still baffles me that Audi called a supercharged V6 a “3.0T”). And it’s a good thing they do, as the job looks like it’s a real pain in the ass.

 

To replace the B8 S4’s PCV, you must first remove the air intake and supercharger, which is a process in itself. Then you get to replace the PCV valve and the hoses that go along with it. After you’re all done, you have to put it all back together and there are a lot of bolts and hoses to remember. So it can be one of those long weekend, case of beer-type jobs.

 

However, that lengthy replacement means that a mechanic is going to charge a small fortune to do it, so you’re better off spending a few hours and spewing a few expletives doing it yourself, if you’re handy enough. This video will help the process go quicker, though. Not only does it tell you what needs to be done, it shows you in great detail and explains each step thoroughly.

 

These sorts of videos will help weekend-warrior mechanics get done quicker, with fewer headaches and more time on the weekend to spend that anger on their football teams. Maybe that’s just me…

I've been in love with cars since I was a kid, specifically German cars. Now I get to drive them talk about them on the internet.
