Hmm im thinking that guide seals could be causing your problem. Oil will be able to pass through the valves without you seeing it on a compression test.
i had a compression check done and all cylinders give between 170-175 psi.
the problem is i blow oil out of the breather in the valve cover. my mechanic is confused too. i have changed the pcv vlave 2 times, both oem from the dealer. any idea as to why i have the positive pressure? it would usually be blow by but all the cylinders give good numbers?
any help would be great

my valves are fine. i have never lost a timing belt. the seal may be a diffrent story. i just need this motor to last until i buld a new one

I had the samr thing happening when I was playing the PCV hose and left it unplugged of the manifold. Since I fixxed it Ive never had any oil in the breather. Check for the that hose being clogged
