Default blue smoke... compression test result interpretation help!

hey i have lil puffs of blue smoke out of my s2, get a big 1 at startup (even if cars only been off for half hour), and throughout (esp when givin the loud pedal a lil kick up tp 2000rpm or so) loads of lil 1s come floatin by the passenger window

did a comp test, got 145ish psi all 4 cylinders when dry, wet test bought em up by about 10 psi, but my collage tutor ses dats ok...

hopin it aint me turbo, done nearly 90k on orig turbo, hasnt been chipped tho, was thinking about changin me valve stem seals but surely it wud only smoke on startup?

any help guys

Have you got any play in the turbo or much oil in the pipes?

It would clear after a while running tho if it was the valve stem seals

My guess is the turbo or a blocked breather?

Have you tried cleaning out the breather? or even fit a new one, there like £7 from ford, also check and clean all the hoses for the breather (left hand side of rocker cover roundish black thing conects to rocker cover/inlet manifold at the top and metering unit) a turbo would smoke when u nail it in 5th from low revs and lift off on overrun, wld be more than just one or 2 puffs aswell
