Hello. So i have replaced quite a few things in this car. Finally got the oil level light to go off and have the triptronic working again. But now i have an ongoing issue which i think is the pcv valve. I have replaced a number of bad air hoses as i had multiple leaks and issues with misfires i had to replace the entire crankcase breather system and pcv valve as those hoses cracked while trying to replace the engine coolant sensor. All was good with that until last year when it started to make this high pitched sound especially while accelerarting but would go away. But after a few months it would be random and more of a high pitch honking noise. After reading it sounds like it was the pcv valve going bad. And i also lifted up the hood and noticed the noise was coming from the pcv valve as well as some vibration noise also coming from this little blue and green cylinder like object that connects air hoses very near the pcv valve
Needless to say, I have replaced the pcv valve 3 times and the noise goes off for a few days or so and then comes back again. Could 3 of these all fail or is something else going on? I also pulled the oil cap ofg without any issues and the engine runs rough which should be happening? I am not sure if buying an authentic part would be better? Just seems like a simple part and for 3 to fail seems odd? I do also get random misfires every so often with a cold start which could be related to this pcv valve. I did run smoke through the vaccum lines and there were no leaks.
