My 2.8 30V was leaking oil. Not so much from the valve covers, but I suspect cam chain tensioner and driver side front cam seal was a bit wet.
Oil smoke on both sides of the engine.

The PCV vent hoses just fell apart when I touched them, also build up inside.

I decided to order the Blaupart set (link for photo below).

Where are the hoses from the kit located and what does it take to change them out?

If you didn't remove all of the old tubes you should be good to go. You undo them by squeezing the ring on the end of each tube and pulling back. You are getting a couple of new valves as well. Most of this stuff goes at the back of your engine under the plate mounted on top of the intake manifold. Just do them one at a time. Blau will have a diagrma as well. Make sure when you get new tubes on thye "click" into place or they are not seated.
