Car Blows Blue Smoke, Cant Pass Emissions.

back again with my second question, you guys helped me figure out the part in my first question and i fixed that part. but now I have another question, i apologize if this was already asked a million times, but what can make your car blow out blue tinted smoke when you first crank it up? i know its oil being burned but what can you do to fix this? i took it to a shop and they said they dont wanna try and fix it because i would need a new motor, i know there has to be other options for this fix. but until i fix it i cant pass emissions and my tags are already expired. the car only blows out the smoke like 1 out of every 8 times i start it up. and the shop said they had the rpms up and it was puffing smoke like a cheminy. i will test that later myself... any suggestions on how to fix this? any and all help would be appreciated.
my car is a 1992 chevy cam, with the 5.0 TBI engine.

Valve guide seals are a known problem on sbc.
What part of the emissions test are you failing?

blue smoke on start up is usually worn valve seals. not hard to change, even with the heads still bolted down.

It's failing the three main things its needs to pass, co readings, nx2 and the hco, I probably listed those wrong but I'm on the way to the shop right now to pick up the car and the emissions paper, then I will be able to tell you.
