    Got all the parts together for the plenum plate replace. Mostly likely will start in the morning. One last test I did was remove the oil fill cap to see if I could feel vacuum after reading about someone else doing this. With the engine idling I help a piece of tissue over the opening and noticed it being pulled in. Most likely a good sign of a defective plenum gasket or something else?

    Did you check the PVC valve? It should have a strong vacuum to it when you take it out and put your finger over it, or like was said hear it clicking, or just take it out with engine off and shake it, it should rattle.

    I have never heard the vacuum at the oil filler cap deal.

    PVC is fine. Air flows one way through it.

    Well, not good. The two front manifold bolts broke off. They absolutely will not budge after heat and soaking overnight in pb blaster. In the process of drilling one out for an extractor bit. Appears the bolt hole goes all the way through the head. Is that correct? I can feel an opening underneath.

    Sorry to hear that mxer! If you feel the opening it probably does go all the way through. I am not sure if it would be threaded all the way. I think the opening on the bottom is so you don't crack the head when tightening the bolts. If there is any water in a closed hole (no opening) and you tighten a bolt it will create hydraulic pressure which can break the bolt hole open.

    Well, got er done! Finally got the bolts out. Used an extractor on one, the other I had to drill out and run a tap through to clean the threads. Also replaced the injector o-rings and water pump. Time will tell if the oil usage problem has been reduced or corrected.

    Update, oil consumption has been reduced. Did not have to add any oil between changes this last time. Although the level was close to the add mark on the stick. So I think all the sweat and work I did was not in vain.
