Hi again  car can be parked on any angle, always on the driver side.  New

rings,  pistons, valves and seals.  valve seats both intake and exhaust have

been  swapped.  Pulled the plugs and none show more burning than another.

Had a high volume oil pump then swapped it out for the old oil pump.   Seams

to burn less oil ( Lots of smoke idle, seems like very little when

accelerating). 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
