Hello. To make a long story short...I discovered a couple rocker arm shafts apparently out of whack:
Actually I pulled out the left shaft a little beyond where I found it. The middle shaft also worked itself out quite a bit. Oil would drip from the bottom corner of the lower valve cover directly beneath where the left shaft sticks out of the housing. Don't think there's much doubt where the bulk of the oil came from.
Reinstallation? The Haynes manual says: "Install the rocker shaft, passing it through its rocker arm. Use a feeler blade inserted between the camshaft housing web and the rocker arm. Keep the blade depressed while the shaft is pushed in. When the feeler blade is felt to engage in the groove in the rocker shaft, withdraw the blade and continue to push the shaft for another 1.6 inch."
Don't know what they mean by "camshaft housing web". They don't say whether to install each shaft moving left or right. Since I can only put the left one in from right to left I assumed they all should installed that way, but what do I know? I stuck the blade on both sides of the rocker. With the blade on the left, both ends of the shaft end up in the cylinder. When I put it on the right, the shaft sticks out the left side a lot further than the others. Neither way produces a match the rest of the shafts; they all stick out maybe 3/16" on the left side (like the one on the right in the photo). It looks more correct with both shaft ends in the cylinder, so something is amiss.
Do you know the correct procedure? By the way, what we have here is a 1989 3.2 that I just pulled out of my 914.
