ok so other day i noticed on a full throttle 4th gear pull and at 7,800 shifted (not speed shifting either) and got a decent cloud of blue smoke now this was OFF LOAD and between gear shifts. i did leak down and comp all are VERY good numbers for the miles/age of motor.

STOCK gsr engine
oem ecu
no cel's
no cat
buddy club spec 2
intake arm.

now i am fig it is blow by BUT why does an issue not show up on leak/comp test?

all comp # are 8% of each other and all still above 200psi
leak down was with in 5%

only other issue i could think is valve seals but fig that would manly do after idle and take off. which i get NO smoke after idling or sitting over night

so what gives
