None of the bolts are drilled (and it was oiling ok last year when I adjusted the rockers). I have the rocker assembly apart and can see the oil holes in the 1st and 3rd rocker stands and the shaft: it's clear that the oil is to come up in the clearance around the bolts (or if it isn't I don't see how it could work).
> Your owners manual will have a lubrication > diagram.
The engine shop manual has a diagram showing that the cam bearings distribute oil to the rockers and the governor but does not detail the route to the rockers.
> I thought it was the middle stand.
The first and the middle stand are drilled with oil ports opening to the shaft. The shaft has a matching hole for the port in the first stand but not for the middle one. Possibly the middle stand does not actually carry any oil despite being drilled.
Perhaps the camshaft bearing is so worn that the oil all leaks out without developing enough pressure at that point to reach the rockers. But if that is true why didn't the oil I poured into the holes drain away quickly?
Perhaps the camshaft oil gallery is clogged. But if so, why do I see lots of oil on the cam followers?
I'm reluctant to spend $275 and a lot of labor on a reman cam until I know what is going on. I'd hate to put that cam in and then need an engine anyway.

Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
