I agree entirely with Michael; but wanted to add one more often-overlooked
problem. Because of the deliberately low flow rate and pressure through the
rocker lube system, it is particularly apt to fill with sludge and fail to lube
the front rockers. It only takes a few minutes to check for this when setting
the valves ... just start the engine and let it idle for a few minutes with the
rocker cover off. You should see oil flow through the front rocker by then; if
not, it's time to clean out the rocker shaft.
I've also not seen anyone mention the increased clearance required with the
phosphor-bronze valve guides that seem to be so popular. More clearance means
more leakage past the stem, which will be oil if that's what's above the guide.
Seals can solve the oil burning problem; but generally keep TOO much oil out of
the guide and hence shorten guide life.
