Hi again  car can be parked on any angle, always on the driver side.  New 
rings,  pistons, valves and seals.  valve seats both inttake and exaust have 
been  swapped.  Pulled the plugs and none show more burning than another.   
Had a high volume oil pump then swapped it out for th old oil pump.   Seams 
to burn less oil ( Lots of smoke idle, seams like very little when  
aclerating). Engine has to warm up slightly for clouds of white smoke to show  up ( 
maybe 2 - 3 minutes).  How about oil return  blockage??????

A few thoughts
First - You installed dual exhaust on this 110, (not stock), so  that is 
how you know it is the left side (AKA drivers side) smoking (as  viewed from 
the rear of the car). Right? When you pulled the plugs, did you do a  
complete compression test? If all 6 are close, try a cylinder leakdown  test. Oil 
in the chamber - needed for exhaust smoke - must come from somewhere.  There 
are only a few paths into the chamber, Intake port, intake valve guides or  
past the rings. Did you install the umbrella-type valve seals? - The kind 
that  snap over the top of the guides. Usually used only on intakes.
 
 Do you have an electronic ignition on the car (No, that can't  cause 
smoking!) IF you do not have electronic ignition, while the car is  sitting there 
idling - and smoking - try (CAREFULLY) removing one plug wire  at a time 
from the left side, causing a cylinder to miss. If/when the smoking  stops, or 
reduces a bunch, that cylinder may be the culprit. If all three smoke,  no 
matter what, keep on searching.Please do not remove a plug wire from a  plug 
while running if you have electronic ignition, that can kill the  ignition 
system. 
 
Make sure the PCV system is correctly installed and no oil is  being fed 
into a carb base or air cleaner side. This is a messy idea, but  if you are 
afraid of oil return issues, you can try running the car without  valve covers 
or just "half-covers" in place. In order to flood the rocker  chamber with 
enough oil to hit the valve guides, you have to have a lot up  there, since 
the valves are near the top! This is especially unlikely at  idle.
 
Good luck - I guess you can ignore my other idea - Never let it idle, full  
throttle all the time!  - Seth Emerson
