Have 2002 honda accord 2.3 that loses a quart of oil in abt 100 miles. Had burned valve when purchased. Had head fixed, all valves replaced. No visible leaks on outside of engine, even with UV dye. Compression is 145 psi in all cylinders, and leak down test showed loss of less than 10%. No smoke when running....ANY IDEAS??

 

No leaks and not burning oil?
Check the PCV valve is function properly.
