I have a 2007 Honda pilot has 188,000 Miles. Lately start blowing white/blue smoke cloud at startup only then clears out. it doesn't loose any coolant. it consumes about (1) Qt of oil every other week (every 300-500 mile). Vehicle is driven pretty much every day. I changed PVC located at the front engine head. Also I have noticed oil in intake manifold concentrated above the third piston in front side (counting from passenger side to driver side). it is soaked in intake body at mentioned location. I need guidance to determine the root cause and a fix plan. Thanks in advance for your help.
