So about a week ago I noticed the famous Volvo squeal on my 2005 s80 2.5t and after some research I concluded that the pcv breather was bad. I changed the pcv and I still had the white smoke in the oil cap and dipstick and squeal. Then after more reading I realized that I didn't clean the PTC valve. So I went back in to rebuild the whole system and clean everything out. I confirmed that everything was assembled correctly and I put it all back together. I took it on a test drive around ten miles. I got home and did the glove test and it got sucked in. So I turned off the car and got ready to go inside the house and call it a day. Then I realized that the car wasn't parked straight on the curb so I went to repark and I heard the squeal noise. I was tired and it was late at night so I just went inside and now I'm here. I have around 130k miles and I need some help. Any help will be greatly appreciated thanks in advance.
