Leakdown results on their own rarely tell the whole story. What are the compression results? Where was the air leaking from (sump, oil tank, etc.)?

Kurt -

Do not know where it was leaking from ... compression test was not performed.

Then you are left with an imcomplete PPI. Cylinders 3,4 & 6 are a bit borderline, but without a compression test who really knows?
