Cam Selection 360

Update:

I've driven this truck about 500 miles since this re-ring job. Mostly been perfect. Zero external gasket leaks, runs really good.

Peculiar observation the other day: I found oil on the intake manifold, leaking from the PCV hose at the carb connection. When I pulled the hose off, it did seem to fit tight on the carb nipple, but I trimmed a small amount off before I reconnected, just to ensure a seal.

That said, how much oil in the PCV hose is "normal"?

PCV valve is an OE type aftermarket. While running, PCV valve removed from the valve cover, no excessive blowby observed. PCV plugged back in, finger on breather hole, I do get a small vacuum on my finger. No oil being pushed out of gaskets. To me, this all points to good ring seal. Additionally, all plugs look ok. It does give one little puff of blue smoke after a LONG (5 minute) idle. This may just be slightly loose valve guides in the original heads, but I'm wondering if this could be related to the oil in th ePCV hose, a situation where oil accumulates in the hose, then gets drawn in after vacuum fluctuates in the line.

Thoughts or experiences?
