wondering if there is some type of additive in the oil that burns off as it warms up,
There should never be any spitting out the breathers if the engine is in good shape,
do you run a PCV system?

You're absolutely sure the oil looks good? No fuel smell, no white streaks, foamy, changes in viscosity? What ever this is, it has to pass through the crank case. I had an old Pontiac 389 that the valve guides were so bad the engine wouldn't run with the valve covers off and it didn't smoke like this. Puffing indicates this is a combustion related issue or at least related to one or a few cylinders not all. Is this a closed cooled motor or seawater? If you have through hull exhaust watch your exhaust closely, have someone follow you and see what your exhaust is doing. What temp does your motor run at?
