The van has 250,000 km on it. Further inspection of all the spark plugs reveals the front plug on the left bank and rear plug on the right bank also had signs of coolant on them. This is the first time I saw this on my van, but then it hit me, Way back in the days before I was all diesel all the time I used to do intake gaskets for this same issue. Threw a set of plugs at it for now and will do intake gaskets next weekend.
I will also look for the hole in the valve cover mentioned.
Thanks guys.
Valve cover turned out to be fine, no hole. The culprit was the intake gaskets. The bottom portion of all the intake port seals were not sealing and sucking in oil. Suprisingly though was the fact that the coolant ports were fine. And I got 250,000 km before having to do them.
