2000 S40 Bad Pcv Can Actually Be A Bad Turbo?

[Peace562]

Hello Everyone,

I have a Question regarding the PCV, Turbo, and The Oil Leaks Rssulting from a Bad Vacuum.

First off, I bought this 2000 Volvo S40 1.9T with 160k.

After about 3 weeks of no Problems. I started to get a Click coming from the Exhaust Cam sprocket and then a Subsequent leak from the respective cam seal.

So I went in and replaced the Gear and seal. All be it with a Used Cam gear.

After the leak returned I took it in to an Indy Volvo service shop where they told me That Besides the bad seal I had Positive crankcase pressure. They said this pressure was causing oil to get pushed past the seals and getting into the T Belt and Gears which was at risk of slipping and Bending Valves. So After being quoted 2k To do all the work I decided to go the DIY way.

So I dismantled the Intake And Got into the breather box I found the ports Not really clogged there was a small amount of Gunk in the bottom port but nothing to the point where air flow could be restricted. I still gave it a good cleaning. Same with the hoses, replaced the breather box. I then went ahead and replaced the cam seal again, huge Pain. After all that I still don't have a Vacuum. Or at Least it's only a Partial Vacuum a rapid intermittent vacuum as Shown in this YouTube Vid I Posted.

Vacuum leak on some other hose. Did you check the idle control hose from ic to tb?

Is This The respective hose? If so I tried to blow thru it and couldn't maybe it's clogged ?

It wasn't that one but I would look at all those to make sure there are no needle /pin size leak. You can get a soapy water solution and spray over them. Turn on the engine and watch I any area get dry up while the rest stay wet.
