Bad PCV Valve! Sympoms, How To Diagnose And Change PCV Valve! Audi TFSI 1.8/2.0

Hey guys, recently I had a bad PCV valve. So in this video I am trying to explain and show you how to replace it, until it's way more expensive to do. Some car manufacturers recommend to replace the PCV at certain amount of time, as the PCV rubber gaskets goes bad overtime and it may lead to quit an expensive fix, as it did to me. At first I thought it was a squeaky belt, but it was the PCV.
I had to replace PCV and change the rear main engine seal, which cost me around 400 bucks. Yeah that sucks. I wish I knew about this problem before rear main seal went bad. Hope I explain everything good and this video will help you!

My 2010 Audi A5 is consuming quite some oil. I hear that if this goes bad that's what causing problems. I don't have other leaks, air filter is clean so no oil going into it. So not sure that it could be piston rings. I also don't have blue smoke or smell of burning oil at exhaust.

btw my 2009 gti is having idle problem, showing P0507( idle higher then expect). during the car running at warm up temperature, every time when it comes to a stop or moving slowly the idle rpm increase it self. way up to 2k then slowly drop like the engine was choking. some people said it is the pcv valve, some said MAF sensor and throttle body. i don't know which to trust.

After replacing it the pcv didn’t suck up anymore air but the oil dipstick and cap do now. It’s pretty bad and the engine starts shaking if I open it while the car is on. Help me please!

Hi! I have no pending codes or CEL but lately my 2016 2.0 feels underpowered and it doesn't respond quick as it used to be, it vibrates it idle or when driving, I did a common maintenance (spark plugs, coils, air filter and MAF AIT clean up) car still vibrating with slow response at the throttle. Can the PCV go bad without codes?

@@MrShootFirstDieFirst I have a B8 A4 2.0T and I tried the test of taking the oil cap off with the engine running and it sounded like it was sucking air more like a vacuum and started to idle rough, I thought that means that the PCV valve is bad so I bought a new PCV valve and got it installed and it’s doing the exact same thing, I got it replaced only because my car was consuming insane amounts of oil like 1 litre every 350 miles so everyone told me to try this first before going for the other options that are crazy expensive
