Question about Geo Metro
The newer engines are very critical to torque specs. If they were not torqued properly, even the slightest, you can have what is occurring. The older vehicles had much higher torque settings and this was hardly ever a problem.

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

Its funny that everyone has solved the problem without any answers to critical questions. In this case, everyone is right and everyone is wrong. ONLY careful testing and observation will determine if there is an actual problem. I do not solve problems just to be first. Even in a hands-on situation I refuse to jump to conclusions before testing, otherwise you run the risk of at best, "chasing your tail" or at worst, tearing into a perfectly good engine to prove nothing!!!
Happy New Year!!!!

Did you put Valve seals in the head???
Other than that the PCV is a good start...
But it sounds like the oil rings on the pistons to me.

SOURCE: mazda mx5 smoking problem
Please provide more details for analysis like:
- what is the mileage on your car?
- is it smoking continously or only intermittently? How much smoke is it?
- what colour is the smoke? bluish or sooty?
- does it smoke when engine is cold or hot?
- is your car losing power?
- is your car consuming motor oil and at what rate?
- has the engine ever been overheated?
- is there an engine MIL ( malfunction indicator light ) code flashing on your dash? If it has, then you need to get the workshop to run a scan of the engine's computer to find out what the possible faults are.
- by the way, is your mx-5 fitted with a rotary engine or the common 4-stroke piston engine?

hi... it all depends on the colour of the smoke... usualy blueish smoke will mean it is oil burning and your piston rings may be getting worn if it is black then it might be running too rich etc.. a little bit of water is fine infact usualy it is a good sign that your engine is not running rich or lean so it is pointing towards oil seals... also if it was running rich it would probably do it more when it was cold
