just my two cents, but i had a modulater go b ad on myold chevy truck and it did the same thing ,it was sucking tranny fluid through the intake causing white smoke

 

It depends also on which valve seals you use. If you have an smoke problem and a little oil consumption problem, valve seals might cover it up if the guides were tooled properly. Use 2 seals on each valve, the regular o-ring seals at the top and use umbrella seals (the wire wrapped rubber ones, not plastic) to help seal it. Might also need to have a compression leak down test performed to see if rings are seated properly. Whoever built the engine might not have gapped the rings properly which would cause some oil problems. Good Luck.

 

Two seals? That's goin' in my mental data bank.
I have a question L. B......
since we all kinda agree on the seal prob, wouldn't the valves eventually develope carbon deposits, that can cause valve (compression) leakage, if the prob is not corrected? Seems so, to me.

 

Yes I guess it would be possible, but it would not be carbon. Really haven't seen much in the way of oil burning causing to much valve problems. Best way to check is to remove spark plugs and check for oil burning which would make the plugs have a brown tint or deposit on them.

 

O. K., thanks!
