<VV> Burning oil

[Robert Paul]

Hi folks I have a real tester of a question for you.  I have a brand new rebuilt 110 engine that burns oil on the driver side only,( 90miles on the re build).  Only when the car is at idle.  There seems to be little or no oil burning when the car is at speed.  The engine has been acid dipped, new valves, pistons, rings, seals, valve seats, etc.  So it is only on the driver side, only when the car is idling....any ideas?  Ive tried everything I can think of.  Thanks in advance. Robert Paul
