Always though OHC engines were more prone to stem-seal oil leak smoke due to the amount of oil hanging around up the top to lubricate the cam.

fault in valve stem you can almost instantly recognice if from exhaust. My car used to have 3.0 Essex and high pressure oil pump
and that totally flooded upper part of engine. I was forced to make plugs for oil holes to make them 30% smaller to reduce
massive flood in valve covers.
Also if you don't use lead additive with fuel valves tend to wear out much faster and that causes also smoky exhaust.
Essex heads gets overheated much easier because water canal/ways are not close to exhaust valves.(Compared to cologne) With high rpm/boost
that tends to wear valves also faster.
Alloy heads and low temperature thermostat helps in this case. IF you make oil holes smaller i suggest to use fully synthetic oil something like 5W-40 or 5W-50. Fully synthetic oil won't burn so easily and block oil canals and has washing/cleaning elements. "Less black sludge problems"

Mineral oil, not so often oil changed....
Fully synthetic, oil change every second year or 5.000 to 6.000 km.
If E85 used as fuel need oil change every 3.000 to 4.000km.

However this standard 3.0 Essex runs just fine on 20W-50 so i think i'll just stay with that, and Valvoline VR1 has 1300ppm and i can get it cheaper than Mobil 1, VR1 has great specs for a Mineral 20W-50, API SM and ACEA A3/B4 , TBN is over 12, base oil is i think Group II, and it also has a good dose of friction modifiers.
