Valve stem seals are gone, not doing their intended job.

You might be able to put GM's spring hood/cup on the valve spring along with replacing the stem seal and installing stem cup seals on the valve stem/guide.

This can be done without removing heads.

Or, remove heads and have headwork done, exchange heads for rebuilt ones, or buy new ones and re-install.

But then, the old wives' tale, "You build the top end, the bottom end will fall out" I personally never experienced this, but

It depends on how deep your pockets are.

Others here may have some good suggestions, on a fix, the question is, how comsumption is there and is the blue smoke really that bad?

The Blue smoke is bad enough for friends to comment about it...seems to happen after I drive the car hard, turn it off and then restart far as oil consumption, 1/2 qrt. in the past 500 miles?....
I've hear about that old "wives tale" and knowing my luck it would happen to me.
I kinda had an idea the valve seals are on their way out...I think I'll try changing them. THANKS!!!

Sounds like the valve guides are bad. That happened to me and I had to take off the heads. The machine shop only charged me $45.00 to replace all of them and thats because they had to replace a bad valve.

The puff of smoke at startup is a Chevy curse! The stock engines really dont have a valve seals like umbrellas or PC type. They have an o-ring that deflects oil. I had a brand new 85 IROC-Z and it did it from the day it was made!!

This alone won't ever hurt the performance of the car if you can live with the big puff of smoke! But, if your using 1qt per 1000 miles, you have a more serious problem like leaks or rings!

Does it smoke blue under hard decelleration? This is a sure sign that the valve guides are wiped out!
